Composition and Properties of Stainless Steel

Conclusion

The functionality of metal expansion nuts centers around the principle of mechanical expansion. Upon the application of torque, the screw or bolt is threaded into the nut, which, in turn, causes the nut to expand outward. This outward expansion presses the sides of the nut against the inner walls of the hole it occupies, creating a tight fit. The added friction and mechanical grip prevent the nut from loosening over time, even in dynamic conditions.

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.
