screw factory in china – only this special long screw!

screw factory in china is not too small, most of the screws only do standard screw, small parts also do non-standard screws, but for long screws, there are only a handful of manufacturers that can make long screws, and Shi Shi Tong is a professional manufacturer. Long screws, extra long screw fasteners.

Shi Shi Tong screw factory in china have received orders for many long screws in the past year, and there are many orders for M5 long screws. Once a customer came to our factory to see our long screws, asked us why these M5 screws are basically half-threaded? And the length of the thread is only 100mm, is there anything to pay attention to?

Since the screw is used as a fastening for the two workpieces. Too long or too short does not make much sense, because the purpose of the screw fastener is to connect the two workpieces together, and the long screws are also produced according to the actual use requirements of the product.

The thread length of the M5 long screw also determines the cost of the screw on the one hand, not necessarily the longer the length of the thread. And if the thread length is too long (for example, more than 100mm), most of the screw factory in china cannot produce it because the boring machine cannot satisfy the production of such a long screw. Therefore, most of the long screws are only half-threaded. If more than 100 threads are required, most of them are welded by the process.
