A wrench is a commonly used tool for installation and disassembly, utilizing the principle of leverage to turn bolts, screws, nuts, and other threaded fasteners with openings or sockets. Wrenches are typically made from structural steel, either carbon or alloy materials.
The issue of "upside down" during the loading and unloading of pull nails has been resolved. By changing the operation position, the operator can easily disassemble the pull nail nut, making it simpler and more convenient to use.
A nut is a component that tightly connects mechanical equipment. It connects with bolts of the same specifications through internal threads. For example, an M4-P0.7 nut can only connect with M4-P0.7 series bolts (in the nut, M4 indicates that the inner diameter of the nut is approximately 4mm).
