M10 Bolts

M10 Bolts — the Standard for Structural and Mechanical Connections

M10 bolts are the go-to metric fastener for medium-duty structural and mechanical connections across Australian industry. With a 10 mm nominal diameter and standard coarse pitch of 1.5 mm, M10 offers substantially more clamping force than M8 while remaining manageable in assemblies where space is limited. From structural steel fabrication and civil construction through to agricultural machinery, mining plant, and industrial equipment maintenance, M10 is one of the most consumed bolt sizes on any maintenance storeroom shelf. AIMS Industrial stocks a comprehensive M10 bolt range in multiple grades, materials, and head styles, ready for fast dispatch from Sydney.

Types of M10 Bolts

M10 hex head bolts (AS 1111.1 / ISO 4014 full thread; ISO 4017 partially threaded) are the industry standard for structural and mechanical bolting — driven with a 17 mm spanner or socket. M10 socket cap screws (ISO 4762, 8 mm hex key drive) provide higher torque capacity and are preferred in precision machinery, fixturing, and where a recessed drive is required. M10 countersunk and button head socket screws cater to flush-finish or low-profile applications. M10 anchor bolts — including throughbolts, sleeve anchors, and wedge anchors — are the dominant fastener for securing structural posts, machinery bases, and rail to concrete. M10 masonry bolts and concrete screws (Tapcon style) allow faster installation without a separate anchor. M10 U-bolts clamp pipe, tube, and conduit. M10 coach bolts are used in heavy timber construction. Galvanised and stainless M10 bolts are heavily used in outdoor and coastal infrastructure.

Grades and Materials

Grade 8.8 M10 hex bolts are the standard specification for general structural and mechanical applications — tensile strength 800 MPa, yield strength 640 MPa, typically zinc-plated. Grade 10.9 M10 socket cap screws are used where higher clamp loads are required in clamping, tooling, and automotive applications (1,040 MPa tensile). M10 stainless steel bolts in A2-70 (304 stainless) and A4-80 (316 stainless) are specified for marine, coastal, food processing, chemical plant, and outdoor structural applications. Galvanised M10 bolts (hot-dip galvanised per AS/NZS 4680) provide long-term atmospheric corrosion protection for civil and infrastructure applications. High tensile M10 bolts are commonly specified in agricultural machinery, mining equipment, and heavy transport.

Thread Specifications and Key Dimensions

M10 coarse pitch is 1.5 mm; fine pitch M10×1.25 is available for vibration-sensitive or thin-wall applications. Hex head across-flats: 17 mm. Socket cap screw hex key: 8 mm. Standard stock lengths: 16 mm to 300 mm for hex bolts; 10 mm to 150 mm for socket cap screws. For M10 anchor bolts, drill size is typically 12 mm hole diameter — confirm with the specific anchor manufacturer's data sheet. Minimum thread engagement for full load: 10 mm in steel, 15 mm in aluminium.

Applications

M10 bolts are specified across a huge range of Australian industries: structural steel fabrication (connection angles, gussets, and cleats in AS 4100 structures), civil and construction (anchor bolts for columns, posts, and plant bases in concrete), agricultural machinery (implements, headers, baler frames, grain augers), mining and quarrying equipment, material handling and conveyor systems, power generation plant, heavy transport and trailer frames, and HVAC and mechanical services. M10 anchor bolts and masonry bolts are among the highest-demand products in any construction or maintenance context.

Choosing the Right M10 Bolt

For most structural and mechanical applications, Grade 8.8 M10 hex bolts with a matching M10 full nut (ISO 4032 / AS 1112) and plain washer (ISO 7089) are the correct assembly. For concrete anchoring, select the anchor type based on base material (cracked or uncracked concrete), load direction (tension, shear, or combined), and edge distance — the AIMS team can advise. For corrosive environments, specify A4-80 stainless or hot-dip galvanised rather than zinc-plated. Always verify that tightening torque is appropriate for the grade and application — overtightening M10 Grade 8.8 to failure is a common site error.

AIMS Industrial stocks M10 bolts in hex head, socket cap, countersunk, coach bolt, anchor bolt, and U-bolt forms in Grade 8.8, Grade 10.9, 304 stainless, 316 stainless, and galvanised steel. Contact our Sydney team for trade pricing, bulk orders, and fast Australia-wide delivery.
