Forgefix Carriage Bolt & Nut - M10 x 130mm - Bag 10 - White

M10 refers to the metric thread size, with a nominal diameter of 10 millimeters. The 130 indicates the length of the bolt, which is 130 millimeters from the underside of the head to the tip of the bolt.

No, these Forgefix Coach Bolts are designed for *low load-bearing applications* only. They are not suitable for critical structural components where high stress or heavy loads are expected. Always consult engineering specifications for structural projects.

Yes, thanks to their zinc-plated finish, these bolts offer good resistance to rust and corrosion, making them well-suited for outdoor applications such as garden furniture, pergolas, and fence panels.

You will need a drill to create pilot holes, an appropriate drill bit (e.g., 9mm or 9.5mm for an M10 bolt), and a wrench or spanner (typically 17mm for an M10 nut) to tighten the nuts. Safety glasses and gloves are also recommended.

While technically possible, these bolts are optimized for timber-to-timber connections where the square neck can embed. For joining metal to timber, other fasteners like hex head bolts with washers are often more appropriate, especially if the metal is hard and won't allow the square neck to seat properly.

This particular pack of Forgefix Coach Bolts & Nuts contains 10 individual bolts, each supplied with its corresponding hex nut, for a total of 10 complete fastening sets.

Ensure the square neck of the bolt is fully embedded into the timber. You may need to tap the bolt head gently with a hammer (use a protective block of wood to avoid damage) to seat it properly into the pilot hole. If the pilot hole is too large, the square neck may not grip.

Check that the bolt and nut threads are clean and free of debris. Ensure the nut is aligned straight before attempting to tighten. If still stiff, a small amount of lubricant (like WD-40) on the threads can help, but do not rely on this to force a misaligned nut.

First, re-tighten the nut firmly, ensuring the square neck is fully seated. If the issue persists, consider adding a flat washer under the nut to provide a larger bearing surface and potentially a lock washer to prevent loosening over time, especially in applications subject to vibration.

This often occurs if the pilot hole is too small for the bolt shank, or if tightening is excessive. Ensure the pilot hole diameter is appropriate for the bolt (slightly smaller than the shank but not so small it forces the timber apart). Avoid over-tightening the nut.
