Forgefix Carriage Bolt and Nut Zinc Plated M8 x 90mm Bag 10

These zinc-plated carriage bolts are designed for timber-to-timber joining and include hex nuts for fastening. They feature a domed or countersunk head and a square section under the head to prevent rotation during tightening. Conforming to DIN 603 and DIN 934 standards, they are suitable for timber joist construction, decking, and furniture assembly. The bolts are fully threaded to a length of up to 100 mm, with offerings in 90 mm lengths as well, providing a durable, corrosion-resistant connection. The zinc coating forms a protective barrier against oxidation and can act as a sacrificial anode if damaged, helping to extend the life of the metal components. This set is commonly used wherever a secure timber-to-timber joint is required and is available with matching nuts for complete installation.

Features

• Zinc-plated steel for corrosion resistance

Applications and installation

Used primarily for fastening timber to timber in construction, decking, and furniture assembly. To install, insert the bolt through pre-drilled holes in the parts being joined, then secure with an M8 nut and tighten with a wrench. The square section under the head grips into the wood to prevent turning during tightening. The zinc coating helps protect against oxidation, providing a longer-lasting finish.
