self threading machine screws, shi shi tong screw supplier

self threading machine screws are similar to machine screws in many respects, but self threading machine screws differ in that the lower part of the shank is designed to engrave threads when the screw is driven into the unthreaded hole. This feature makes self-tapping screws more advantageous than self-drilling screws because new threads are not cut if the screws are reinstalled. Self-tapping machine screws have many different drive methods, head types and types, each with its own advantages. Common models offered by the Shi Shi Tong screw factory include AB, A, B and F self-tapping screws.

self threading machine screws have a wide range of top and thread modes and are designed with almost any possible screw head. A common feature is that the thread covers the entire length of the screw from the top to the head and a distinct thread is hard enough to the desired substrate, often requiring surface hardening.
