Why is the thread length of the m5 long screw not so long?

Shi Shi Tong screw manufacturers have received orders for many long screws in the past year, and there are many orders for m5 long screw. 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 not long, is there anything to pay attention to?

The reason why these m5 long screw are semi-threaded, is mainly produced according to the needs. And if the thread of the M5 long screw is full thread, it takes a lot of time to screw it in. Therefore, the customer also wants to save time in this part, so he made a half thread.

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), Shi Shi Tong can’t do it. Because the range of the Caspian screw manufacturers’ boring machine is within 100mm.
