Is small stainless screws broken because what?

Usually, the use of stainless steel screws is not easy to break, only in special circumstances, small stainless screws will appear this phenomenon of fracture, then why stainless steel screws will be broken? The extra-long screw manufacturer will share with you what are the causes of breakage

1. Check whether the pre-hole is appropriate, and the pre-hole too small screw will be broken when entering. So when we are buying stainless steel screws, – must recognize good, in case we buy back is inferior products, in the use of the process to bring unnecessary trouble to themselves.

2, small stainless screws used by the quality of raw materials, stainless steel screw wire quality is poor. There are many impurities, impure, resulting in the stainless steel screw hardness is not enough

3, the customer in the use of stainless steel screws, too much force. – You should take the torque test to see what the minimum breaking force is, and then adjust the torque. If the screw torque is required to do high on the screw to do heat treatment, the current stainless steel 410 material can be hot: treatment, after heat treatment of stainless steel 410 screws, surface hardness HV580-680, core hardness for HV350-450.

4. Production process of small stainless screws. For example, eccentric head of stainless steel screws, and production manufacturing when the Q value is too deep and R bit design is too small
