Truss screw with cross hole for embedded seat nut
This is a screw that incorporates a washer used to prevent loosening and to avoid the sinking of the seat surface. The screw threads are rolled with the washer in place, ensuring that the washer does not come off the screw. This eliminates the hassle of inserting the washer, prevents it from falling out, and improves work efficiency. The truss head has a rounded shape, resembling the top of a sphere that has been cut off. It is lower in height and has a larger outer diameter compared to a pan head. Its large contact area allows for effects such as preventing loosening. Additionally, because it has an aesthetically pleasing appearance, it is often used as a decorative screw in home appliances and office furniture, with surface treatments to match colors and finishes.
