Timco M10 x 40mm Zinc Plated Carriage Bolts & Nuts (50 Pack)

The Timco M10 x 40mm Carriage Bolts & Nuts set provides a reliable fastening solution for timber applications. These bolts feature a domed head with a square anti-spin shoulder that prevents rotation during tightening, making them ideal for clamping timber or attaching ironmongery to wooden surfaces.

Each bolt is manufactured from grade 4.8 carbon steel and features a zinc-plated finish for corrosion resistance. The bolts are fully threaded up to 150mm in length (this 40mm version is fully threaded) and come complete with matching hex nuts for immediate use.

Key features include metric threading (M10) for compatibility with standard nuts and fixtures, and a 24mm diameter dome head that provides a neat finish while distributing clamping force effectively. The square shoulder under the head digs into wood to prevent spinning during installation - a characteristic that makes carriage bolts particularly useful for timber constructions.

This 50-piece set offers excellent value for professionals and DIY enthusiasts undertaking projects involving timber framing, decking, fence building, or general woodworking applications where a secure, non-rotational fastening is required.
