Excellent stainless steel press rivet screws require excellent raw materials to meet the specifications, basically from the following eight aspects:

1. Requirements for stainless steel press rivet screws in terms of mechanical functions, especially strength;
2. Requirements of working conditions on anti-corrosion function of data;
3. Requirements of working temperature on the heat resistance function (high temperature strength, oxidation resistance function) of data;
4. Request for temporary data processing function in production process; Aotian Hardware
5. Other aspects, such as weight, price and acquisition, should be considered.
6. If the tooth is anti clockwise, use a screwdriver or other things and a hammer to knock it anti clockwise.
7. If it can be welded and is not too tight: weld a screw on the fracture and twist it out.
8. Drill a groove at the fracture, which is the same as a slotted head screw, then insert a steel sheet with the same thickness as the groove, and twist it out with a pair of pliers or vice.
