Everyone is no stranger to small stainless steel screws, whether in life or industry, they are used in many places. So, during the production process, have you encountered any broken stainless steel screws? Generally speaking, this kind of situation is relatively rare, and under certain circumstances, there will still be breakage.
1. Excessive force is greater than the destructive torque of the product. Generally, the manufacturer’s packaging box will mark the safety torque table. Use a torque wrench to adjust the value to the safe range. When the wrench makes two "clicks" during the locking process, it means The used inside has reached the set value. This verification shows that the product is not marked with torque or because the force is greater than the safe torque of the product.
2. Product locking leads to twisting and breaking. Locking mainly refers to the direct blocking/shearing of metal teeth, and then adhesion, which will completely lock the small stainless steel screws and can no longer be removed or locked. Because stainless steel has good ductility, when stainless steel fasteners are locked, the pressure and heat generated between the teeth will destroy and erase the chromium oxide layer during the period.
3. The scandium tensile strength or torque of the product itself is unqualified. To put it bluntly, the product quality is unqualified. It is nothing more than the manufacturer's choice of inferior raw material stainless steel wire in order to save costs, or problems in the production process.
