The biggest difference between self tapping screws and machine screws are these: self – tapping is direct, while machine screw requires a nut.Many people have seen that ultra low head no slotted screw, and will continue to ask: how to remove the screw? Must not see inside, usually this kind of screw many are machine thread, or have a nut at the bottom of the set of the below, unless special custom design security tamper proof screw, could design ultra low and does not need to set of the screw nut.

If you can’t distinguish the screw from the machine screw and self tapping flat end screw. Just put them together and compare them, and you’ll see immediately. Shi Shi Tong screws are specialized in the production of self-tapping screws and machine thread screw, in this aspect is relatively rich production experience, complete equipment, standard and non standard can be produced.
