32mm self drilling screws

One of the key advantages of stainless steel self-threading screws is their durability and resistance to rust and corrosion. Stainless steel is a high-quality material that is known for its ability to withstand harsh environmental conditions, making it an excellent choice for outdoor applications where exposure to moisture and humidity is a concern. This means that stainless steel self-threading screws are ideal for use in outdoor decking, fencing, and other structures that are exposed to the elements.

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.
