Set screw with cross hole for embedded seat.
Seat bolt with cross hole and upset small screw
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 incorporated, ensuring that the washer does not come off the screw. This eliminates the hassle of inserting the washer, prevents it from falling out, and helps improve work efficiency. The head is formed into a hexagonal shape through cold forging, and typically has a recess on the top surface. At first glance, it looks like a hex bolt, but it also has a cross hole, allowing it to be tightened using various tools such as screwdrivers, wrenches, and spanners. Due to this advantage, it is suitable for places where the frequency of attaching and detaching is relatively high and where multiple people need to attach and detach it. It is commonly used in automobiles and other applications.
