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.

The unique design of these bolts often includes a sharp, tapered end that aids in penetrating the material. The threads on the shaft of the bolt are designed to cut into the base material, forming a secure and strong fastening connection. This attribute is especially valuable in construction and manufacturing settings, where time and precision are critical.

1. Enhanced Stability The design of the 4PCS fix anchor facilitates a more stable installation, minimizing the risk of loosening over time. This is crucial for maintaining structural integrity, especially in high-traffic areas.
