What is the cause of the problem with csk machine screw?

Regardless of the type of screw, there are basically some big and small problems, so how do you solve these problems? Such as stainless steel csk machine screw.

1. The surface of the screw is not bright

Some people have strict requirements on the surface of stainless steel screws. If the surface of csk machine screw is dark and not so bright, they may return them to the screw manufacturer. In this case, the manufacturer usually negotiates with the customer, saying that the returned goods are taken again for cleaning, and the surface of the screws is cleaned and delivered to the customer.

2. Thread cannot pass the pass gauge

Many people generally check the screw for inspection when checking the thread of csk machine screw. The screws that can pass are the screws that meet their standards. But sometimes there are screws that can’t pass the pass gauge. What is the problem with the screw not being able to pass the stop gauge?

There are generally several reasons: one is that the manufacturer does not use the standard line for production at the time of production, and uses a smaller circle of wire for production; one is that the manufacturer uses the wrong plate during the fangs, resulting in the thread size. Inconsistent; the third is when the head is opened, the polished rod part is enlarged, there is no way to control the size of the thread when the tooth is lost; the fourth is that there is debris in the threaded part, which makes it impossible to pass the gauge.

This usually happens to the manufacturer and asks them to arrange for a new tooth decay or re-production.

3. The head of the screw is easy to break when screwed

One is that there is a problem with the design of the screw, which causes problems in the head when it is used. One is to use the torque of the csk machine screw to twist the screw, so the head of the screw will be broken; one is the slot of the screw. Deeper, it will break when screwing this screw.

In this case, either redesign the screw or do not use the torque of the screw to remove the screw.
