Forgefix Coach Bolt & Nut - M10 x 110 - 10 Pack - Silver

'M10' refers to the metric thread diameter of 10mm. '110' refers to the bolt's length, which is 110mm from the underside of the head to the tip of the thread.

The square neck is a key feature that allows the bolt to grip and embed itself into timber. This prevents the bolt from rotating when you tighten the nut from the other side, making installation easier and more secure.

Yes, the zinc-plated finish provides good resistance against corrosion, making them suitable for many outdoor applications like garden furniture, pergolas, and fence panels. For highly exposed or marine environments, additional protection might extend their lifespan.

No, these bolts are specifically designed for low load-bearing applications. They are not intended for heavy-duty or primary structural elements that support significant weight or high stress. Always select fasteners appropriate for the load requirements of your project.

While the bolts come with nuts and can be used without washers, adding a flat washer under the nut is generally recommended. It helps to distribute the clamping force over a larger area, reducing the risk of crushing the timber and providing a more secure joint.

You will need a drill, a drill bit (typically 10-11mm for an M10 bolt), and a wrench or spanner that fits the M10 hex nut (common sizes are 17mm or 19mm).

While possible, it's generally not recommended for critical applications as the threads or the bolt's integrity might be compromised during removal or previous use. For best results and safety, use new bolts for each installation.

Ensure the square neck of the coach bolt is fully embedded into the timber. You might need to gently tap the bolt head with a hammer to seat the square section firmly into the wood.

Check that you are using the correct size wrench for the nut and that the threads on both the bolt and nut are clean and undamaged. Ensure the bolt is inserted straight and not at an angle, which can cross-thread the nut.

Verify that the pilot hole diameter is appropriate for the bolt (slightly larger than 10mm) and that it's drilled straight through the timber. If the hole is too small, enlarge it slightly. Do not force the bolt as it may damage the timber or bend the bolt.

This often occurs if the pilot hole is too small or if you overtighten the nut. Ensure the pilot hole is adequate. For softer timbers, consider using a washer under the nut to distribute the load more evenly and avoid overtightening.
