When first contacting the screw industry, the socket screw flat tail self-tapping and the LED lighting screw machine thread are always mixed together. Sometimes even seeing the socket self-tapping flat-tail screw, it will be judged as a machine thread screw for LED lighting, and it will also be judged as a self-tapping screw when you see the machine-tooth tip and tail switch screw and so on.

 

Many people know self-tapping screws, but they are only limited to self-tapping pointed-tail screws, that is, screws with pointed tails or drilled tails, but they don’t know that there is another kind of switch screws with machine-threaded pointed tails. The pitch of self-tapping screws is generally relatively large. This is to quickly "self-tapping" to the place to be tapped. Compared with the above two screws, you can quickly distinguish which one is a self-tapping screw and which The model is a machine threaded tip and tail switch screw. The biggest difference between self-tapping screws and machine-threaded screws is that self-tapping is direct tapping. Some parts of the machine-threaded threads require nuts, while the machine-threaded tip and tail switch screws do not require nuts.

 

Many people have seen the kind of flat head screws without grooves, and then they keep asking how to take out this kind of screw without seeing the inside. Usually many of these screws are machine threads, and there are threads on the bottom or bottom. The nut is sleeved, unless it is a special custom-designed anti-theft and anti-disassembly screw, a flat-head screw without a nut may be designed.

 

If the socket self-tapping flat-tail screws, the machine-threaded tip switch screws and the self-tapping tip socket screws are unclear, just put the three together, and you can see it right away. Jinhe Hardware is specialized in the production of self-tapping pointed tail LED lighting screws, machine threaded pointed tail switch screws, and self-tapping flat tail socket screws. In this regard, it has relatively rich production experience, complete equipment, and standard non-standard Can be produced.
