Wood Bolt

Wood bolts are steel shanks with full or partial thread cutting, a pointed end and a hex head. The fastener requires an anti-corrosion coating, since wood always contains a certain percentage of moisture. Types of fasteners for joining wooden elements:

• Double-threaded studs — have no head; nuts with washers are tightened on both ends for a secure fastening.
• Carriage bolts — used to fasten boards together or to a timber beam.
• Machine bolts (with a hex head) and carriage bolts (with a rounded dome head) — used to attach wooden elements to a steel base.

To reduce the risk of crushing the wood surface, a metal washer is placed under the head, optionally with a rubber or elastomer sealing gasket.

The parameters of a wood bolt are determined by the diameter and length of the shank.
