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.

Another significant advantage of the 5 8% wedge bolt is its capacity to withstand vibrations. In machinery and equipment where vibration is a common occurrence, traditional bolts may experience loosening over time, leading to potential failures. The wedge design inherently resists this loosening effect, ensuring that assemblies remain secure even in the most challenging operational environments.

2. Proper Installation Ensure that the screws are driven in straight to avoid damaging the materials. Over-tightening can strip the threads, while under-tightening may lead to loose connections.

Another compelling advantage of self-drilling screws is the secure fastening they provide. The design of these screws allows for a strong bond between materials, ensuring that connections hold up over time. The 2-inch length is particularly useful for thicker materials or applications requiring additional grip. The deep threads and robust shaft of these screws help enhance their load-bearing capacity, making them an excellent choice for high-stress applications.
