Eye Nuts, Eye Bolts & Eye Screws

AIMS Industrial stocks 45 eye bolt, eye nut and eye screw products across Austlift, Beaver, Yoke, Inox World and Hobson — every one of them a rated lifting or rigging component, not a general hardware-store eye bolt. That distinction matters: an eye bolt is one of the few fasteners that doubles as safety equipment, and the range here is built accordingly, to DIN 580 (eye bolts), DIN 582 (eye nuts), AS/NZS 2317 (collared eyebolts and eyenuts), BS 4278 and BS 529, plus Grade 80 and Grade 100 weld-on lifting points. We've put together a Eye Bolt Guide: DIN 580 vs BS 4278, WLL Ratings, Angle Loading & Correct Installation for Australian Rigging if you'd like more detail before you buy.

The range covers swivel eye bolts, collared (shoulder) eye bolts, oblong long-series eye bolts, DIN eye nuts, G80 weld-on lifting points, stainless steel (304/316) eye bolts and eye nuts for marine and corrosive environments, and eye screws for timber and lighter fixing work. If you're after a general fastening-grade eye bolt for a non-lifting job — hanging a light fitting, tensioning a wire, a garden gate latch — this range will still get the job done, but every product here is manufactured and sold as rated lifting hardware, so you're never paying for capacity you don't need.

Quick reference

Exact WLL, thread pitch and material grade vary by size and standard within each product — check the rating stamped or tagged on the item, or the individual product page, before use.

Types of eye bolts and eye nuts we stock

Swivel and pivoting lifting points

A swivel eye bolt has a bail that pivots on the shank, so the pull stays aligned with the load as the sling angle changes — the standard choice for multi-leg slings and any lift that isn't a straight vertical pull. Austlift and Yoke both supply swivel lifting points in this range, including long-thread and key-locking variants for deep or blind holes.

Collared (shoulder) eye bolts

A collared or shoulder eye bolt has a machined shoulder that seats flush against the mounting surface, resisting the bending load that a plain-shank eye bolt can't handle off-axis. This is the standard AS/NZS 2317 and DIN 580 pattern, and it's the bulk of the forged eye bolt range here — from Austlift, Beaver and Hobson, in zinc-plated, black and stainless finishes.

Oblong and long series eye bolts

Where a standard-length eye bolt can't achieve full thread engagement — deep tapped holes, thick mounting plates — a long series or oblong eye bolt gives the extra shank length needed. Austlift's Oblong Eye Bolt Long Series covers this.

Eye nuts (DIN 582)

An eye nut is the female equivalent of an eye bolt: an internally threaded nut with an eye loop, used to turn an existing stud or through-bolt into a lifting point. Austlift, Beaver and Hobson all supply DIN 582 eye nuts in zinc-plated and stainless finishes, plus Austlift's bow eye nut variant.

G80 and G100 weld-on lifting points

Weld-on lifting points are welded directly onto machinery, hoppers and fabricated steelwork to create a permanent attachment point, rather than relying on a tapped hole. Austlift supplies Grade 80 weld-on points (WP and WH/hook types) and Yoke supplies Grade 100 weld-on and super weld-on points — both higher-strength grades suited to permanent installation by a qualified welder to the manufacturer's procedure.

Stainless steel eye bolts and eye nuts

Inox World supplies a dedicated 304 and 316 stainless range — collared eye bolts, mini eye bolts, DIN and JIS collared eye nuts, and lag eye screws — plus Austlift and Beaver offer 316 stainless versions of their standard collared eye bolt and eye nut lines. Stainless is the right call anywhere zinc-plated carbon steel would corrode faster than the application can tolerate: marine environments, wash-down areas, coastal sites and food or chemical processing.

Material and finish options

• Zinc plated / zinc yellow passivate steel — the standard finish for general industrial and construction use, giving a reasonable level of corrosion resistance at the lowest cost.
• Black finish — an uncoated or black-oxide finish, used on some BS 4278 pattern eye bolts.
• Grade 80 / Grade 100 alloy steel — higher-strength forged steel used in the weld-on lifting point range, giving a higher strength-to-size ratio than standard carbon steel eye bolts.
• 304 stainless steel — good general corrosion resistance for indoor and mild outdoor use.
• 316 stainless steel — the marine-grade option, specified for coastal, wash-down, food-processing and chemical environments where 304 or zinc-plated hardware will corrode faster.

Sizing and selection

Get these four things right before you order:

• Thread size and pitch — match the tapped hole or stud exactly; metric and imperial (BSW/UNC) threads are not interchangeable. This range covers metric DIN/AS 2317 pattern and imperial BS 529/BS 4278 pattern threads.
• Thread engagement — as a rule of thumb, full engagement in tapped steel needs at least 1.5× the bolt diameter of thread depth (more in aluminium or softer materials); use a long series eye bolt where the hole isn't deep enough.
• Loading direction — a standard collared eye bolt is rated for straight vertical pull. If the sling angle will pull the eye off-axis, use a swivel lifting point rated for that angle, not a standard collared eye bolt loaded sideways.
• Environment — zinc-plated steel for general dry use, 304 or 316 stainless for marine, wash-down, food or chemical environments.

Lifting-rated hardware — what to check before you lift

The eye bolts, eye nuts and weld-on points in this range are manufactured and sold as rated lifting and rigging hardware, made to recognised standards including AS/NZS 2317, DIN 580, DIN 582, BS 4278, BS 529 and Grade 80/100 specifications. That still leaves selection and use up to you — a few points that matter every time:

• Check the rating marked on the eye bolt, nut or lifting point itself, and confirm it's appropriate for your load with an adequate safety margin — don't assume based on size alone.
• Standard (non-swivel) eye bolts are rated for straight vertical pull. Loading the eye at an angle reduces the safe capacity significantly — for any lift where the sling angle isn't dead vertical, use a swivel lifting point rated for that angle instead.
• Make sure the eye bolt or eye nut threads fully into sound base material, and that the mounting surface is clean and square so a collared eye bolt's shoulder can seat properly.
• Weld-on lifting points must be welded by a competent person following the manufacturer's welding procedure — an incorrectly welded point is not a rated lifting point.
• Inspect eye bolts and eye nuts before each lift for thread damage, cracking (particularly at the base of the eye and the thread root), corrosion and deformation. Damaged or worn hardware should be taken out of service, not downgraded to "non-lifting" use.
• For ongoing lifting applications, follow your workplace's periodic inspection and record-keeping requirements under your state or territory WHS regulations.

This is general product guidance, not a substitute for a competent person's assessment of your specific lift. If you're not sure a product in this range is the right rating or configuration for your job, talk to our team before you use it.

Applications

Eye bolts, eye nuts and weld-on lifting points from this range are used to create rated lifting and anchorage points on machinery, fabricated equipment, hoppers and skips; as termination and connection points for wire rope, chain and slings in rigging work; for load restraint and tie-down on vehicles, trailers and structures; and — in stainless — on marine vessels, dock equipment and food or chemical processing plant where corrosion resistance matters as much as strength.

Frequently asked questions

What's the difference between an eye bolt and an eye nut?

An eye bolt is a threaded shank with a loop (eye) at one end — it threads into a tapped hole to create a lifting or anchor point. An eye nut is the female equivalent: an internally threaded nut with an eye loop that threads onto an existing bolt or stud, turning it into a lifting point without needing a tapped hole in the structure itself.

What's the difference between a collared (shoulder) eye bolt and a plain eye bolt?

A collared or shoulder eye bolt has a machined shoulder that sits flush against the mounting surface, giving it resistance to the bending load created by an angled pull. A plain-shank eye bolt has no shoulder and should only ever be loaded in a straight vertical pull — side-loading a plain eye bolt bends the shank and reduces its capacity sharply. Every collared eye bolt in this range is the shoulder pattern, built to AS/NZS 2317 or DIN 580.

Can I lift at an angle with a standard eye bolt?

Not safely, in most cases. Standard (non-swivel) eye bolts are rated for straight vertical pull, and loading the eye off-axis reduces the safe working capacity significantly — the exact derating depends on the eye bolt design and angle, so check the manufacturer's rating rather than estimate it. For any lift where the sling legs won't be dead vertical, use a swivel lifting point instead — the pivoting bail keeps the pull aligned with the load at any angle within its rated range.

What is a G80 or G100 weld-on lifting point used for?

A weld-on lifting point is welded directly to machinery or fabricated structural steel to create a permanent lifting point, commonly used on hoppers, skips and heavy fabricated equipment. Austlift's range is Grade 80; Yoke's is Grade 100 — both higher-strength forged grades. Because it's a welded connection, it must be installed by a competent welder following the manufacturer's specified procedure to be a valid rated lifting point.

When should I use a long series or oblong eye bolt instead of a standard one?

When the tapped hole is deeper than a standard eye bolt's thread length can fill — for example, a thick mounting plate or a deep-tapped machinery point. Full thread engagement (a common rule of thumb is at least 1.5× the bolt diameter in steel) is needed for the eye bolt to carry its rated load, and a long series or oblong pattern gives the extra shank length to achieve that in a deep hole.

Why choose 316 stainless steel over zinc-plated steel?

316 stainless resists corrosion far better than zinc-plated carbon steel in marine, coastal, wash-down, food-processing and chemical environments — where plated steel hardware can corrode within months. Inox World's range is dedicated 304/316 stainless, and Austlift, Beaver and Hobson each offer 316 stainless versions of their standard eye bolt and eye nut lines for the same reason.

What standards do AIMS's eye bolts and eye nuts meet?

Depending on the product, this range is manufactured to AS/NZS 2317 (Australian standard for collared eyebolts and eyenuts), DIN 580 (metric eye bolts) and DIN 582 (metric eye nuts), BS 4278 and BS 529 (British eyebolt standards, metric and Whitworth/imperial thread respectively), or supplied as Grade 80/Grade 100 rigging hardware. Check the individual product listing for the specific standard that item is made to.

How do I check an eye bolt is safe to use?

Before each lift, check the rating stamped or tagged on the eye bolt or eye nut against your load, and inspect it for thread damage, cracking (particularly at the base of the eye and the thread root), corrosion and any bending or deformation. Confirm it's threaded fully into sound material and, for a collared eye bolt, that the shoulder is seated flush. Take any damaged or worn item out of service rather than continuing to use it.

Can I use these eye bolts for non-lifting jobs, like tie-down or general fixing?

Yes — rated lifting hardware works perfectly well for lighter-duty jobs like tie-down points, stay wire terminations or general anchoring; you're simply not using its full rated capacity. The eye screws in this range (lag/coach pattern, stainless) are aimed more squarely at that kind of lighter fixing and cable-termination work rather than overhead lifting.

What thread types are available — metric or imperial?

Both. Most of the range is metric (DIN 580/582 and AS/NZS 2317 pattern, threads from around M6 up to M30 depending on the product), and Austlift and Beaver also supply imperial thread patterns — BS 529 (BSW/Whitworth) and UNC — for older or imperial-specified equipment.

Do you stock eye bolts in bulk or trade quantities?

Yes. Request a quote for bulk or trade pricing on any product in this range, or contact our team to check stock availability for a specific size or standard.

Which brand should I choose?

All five brands in this range — Austlift, Beaver, Yoke, Inox World and Hobson — supply rated lifting and rigging hardware to recognised standards, so brand choice generally comes down to the specific type, standard or thread pattern you need rather than a difference in quality. Austlift has the broadest range across types and finishes; Inox World is the dedicated stainless specialist; Yoke's Grade 100 range suits higher-capacity permanent points. If you're not sure which fits your application, ask our team.
