Tackle structural fastening and heavy-duty repairs with our comprehensive range of M6 nuts, bolts, and washers. Featuring a standard 6mm metric thread, these fasteners are the industry standard for construction, automotive work, and machinery maintenance where a robust, high-strength connection is non-negotiable. Whether you are bolting down timber frames, securing metal racking, or assembling furniture, our M6 fixings deliver the mechanical holding power and shear resistance required for professional-grade results.

Our selection caters to every trade requirement, from high tensile set screws and coach bolts for structural timber joins to roofing bolts designed specifically for thin sheet materials. We also stock threaded bars for custom-length applications and a variety of locking solutions, including nylon lock nuts, wing nuts, and pronged tee nuts. Choose zinc-plated options for reliable indoor durability or stainless steel for superior corrosion resistance in exposed environments. Equip your kit with trusted components from leading brands like FandF, Apex, and Forgefix.

Frequently Asked Questions | FAQ

What size spanner do I need for an M6 nut?

A standard hexagon M6 nut or bolt head typically requires a 10mm spanner or socket. Always verify the specific head type of your fastener, as some specialized bolts (like roofing bolts) may use screwdriver slots instead.

What is the clearance hole size for an M6 bolt?

To allow an M6 bolt to pass through a material freely, you should drill a clearance hole of 6.5mm or 7mm. This provides enough room for the 6mm shank to fit without binding while ensuring the head and washer still grip the surface securely.

What is the difference between an M6 bolt and an M6 set screw?

In trade terms, an M6 bolt typically features a plain, unthreaded section of the shank under the head, whereas an M6 set screw is fully threaded all the way to the head. Set screws are often preferred when fastening into a tapped hole or when maximum thread engagement is needed.
