An M6 hex head bolt is characterized by its nominal diameter of 6 millimeters. The M classification indicates that the bolt is metric, which is essential for compatibility in international applications and standardized manufacturing processes. The hexagonal head allows for easy tightening and loosening using standard tools like wrenches or sockets.

When selecting hex screws for your woodworking project, consider factors such as the type of wood you’ll be using, the required strength of the connection, and whether the screws will be exposed to moisture or outdoor elements. For example, if you are working with pressure-treated lumber outdoors, opting for stainless steel hex screws will prevent rust and ensure longevity.
