M10 Nuts, Bolts & Washers

Anchor heavy-duty timber frameworks and structural steel with our robust range of M10 nuts, bolts, and washers. Defined by their substantial 10mm metric thread, these fasteners provide the high shear strength and load-bearing capacity required for construction, agricultural machinery, and automotive suspension work. Whether you are bolting down heavy garden gates or assembling industrial racking, our M10 fixings ensure a secure connection that withstands significant stress and movement.

Choose from a wide variety of head types and finishes to suit the specific demands of your site. We stock high tensile set screws for critical engineering tasks, coach bolts for heavy timber construction, and threaded bars for creating bespoke fastening solutions. For added security, pair your fixings with nylon lock nuts or spring washers to prevent loosening over time. With corrosion-resistant finishes including zinc plating and stainless steel available from top trade brands like FandF, Apex, and Forgefix, you can rely on these components to perform in the toughest environments.

Frequently Asked Questions | FAQ

What size spanner do I need for an M10 nut?

A standard hexagon M10 nut or bolt head typically requires a 17mm spanner or socket. However, it is always best to check your specific fixings, as some standards (like DIN) may use a 16mm head, though 17mm is the most common in the UK trade.

What size drill bit should I use for an M10 bolt clearance hole?

To allow an M10 bolt to pass through material easily, you should drill a clearance hole of 10.5mm or 11mm. This ensures the bolt fits without binding while allowing the head and washer to sit flush against the surface.

How much weight can an M10 bolt hold?

The load-bearing capacity of an M10 bolt depends entirely on its grade (tensile strength). A standard 8.8 grade high tensile M10 bolt is significantly stronger than a mild steel equivalent. Always check the grade rating stamped on the bolt head and consult structural guidelines for critical load-bearing applications.
