Hobson Fasteners — Bolts, Nuts, Screws, Washers & Industrial Fixings

Hobson Engineering is one of Australia's leading fastener brands — a specialist in bolts, nuts, screws, washers, rivets and industrial fixings that maintenance teams, engineers and fabricators have relied on for decades. With hundreds of Hobson products in the AIMS Industrial range, the collection covers high tensile hex head bolts, socket head cap screws, button head socket screws, nyloc nuts, machine screws, washers and specialty fixings across metric sizing and multiple finish options including zinc plated, plain and nylon. When you need to bolt, fix or secure something in a manufacturing plant, mining operation or workshop, Hobson has the fastener.

High Tensile Bolts, Socket Cap Screws & Structural Fasteners

Hobson's bolt and structural fastener range covers the high-strength grades and configurations demanded by industrial maintenance and fabrication — from Class 8.8 hex bolts for structural connections to Grade 12.9 socket cap screws for precision machined assemblies:

• Metric Socket Head Cap Screw Grade 12.9 – Zinc Finish: High-grade 12.9 alloy steel socket cap screw with zinc coating for corrosion resistance; the preferred fastener for machine component assembly, jig and fixture work and high-load structural joints
• Metric Socket Head Cap Screw Grade 12.9 – Plain Finish: Same 12.9 high tensile specification in plain (uncoated) finish for applications where zinc plating is not required or where post-installation coating will be applied
• Metric Button Head Socket Screw Grade 12.9 – Zinc Finish: Low-profile button head design for applications requiring a flush or semi-flush fastener head; high tensile 12.9 grade for demanding load requirements
• Hex Flanged Serrated Bolt Class 8.8 – Zinc Plated: Flanged bolt with integral serrated washer face for vibration resistance; ideal for machinery, plant equipment and anywhere bolt loosening from vibration is a concern

Nuts, Machine Screws, Washers & Specialty Fixings

Hobson's complementary range covers nuts, machine screws, washers and specialty fixings to complete every fastening application — from standard hex nuts to vibration-resistant nylocs, Phillips machine screws for panel work, and nylon fasteners for electrical and chemical environments:

• Nyloc Hex Nut Class 8 – Zinc Plated: Prevailing torque nyloc nut with nylon insert to resist loosening under vibration; the go-to locking nut for machinery, vehicles and equipment subject to dynamic loads
• Pan Phillips Metal Thread Screw – Mild Steel Zinc Plated: Standard pan head Phillips machine screw for general metalwork fastening; available across the range in multiple diameters and lengths for panel, electrical and light fabrication work
• Countersunk Phillips Metal Thread Screw – Zinc: Countersunk Phillips machine screw for flush-face fastening in panels, covers and housings; zinc plated for corrosion resistance in industrial environments
• Metric Hex Head Set Screw DIN 933 – Natural Nylon: Fully threaded nylon hex head screw for non-conductive, chemically resistant fastening; suited to electrical enclosures, chemical plant and food processing environments

People Also Ask — Hobson Fasteners

Q: What fastener classes does Hobson stock?

Hobson's bolt and structural fastener range spans Class 4.6 through 12.9 — from Class 8.8 hex bolts for structural connections up to Grade 12.9 socket cap screws for precision machined assemblies — giving a full grade range for general, structural and machinery fastening.

Q: What does the serrated flange do on a hex flanged serrated bolt?

The serrated washer face under the flange has teeth that bite into the mating surface under torque, giving active resistance to loosening under vibration — beyond what a plain flange (which just spreads clamping load) provides. It's suited to machinery and plant equipment where bolt loosening from vibration is a genuine risk.

Q: Does Hobson make nylon fasteners?

Yes — Hobson's range includes fully threaded nylon hex head set screws (DIN 933) for non-conductive, chemically resistant fastening, suited to electrical enclosures, chemical plant and food processing environments where a metal fastener isn't appropriate.
