What are the Bolt quality problem?

The screw produced is likely to cause screw quality problems due to unreasonable production. In production, many screw quality problems may be found at the time of delivery. Let's talk about the quality problems that screws often encounter and the reasons for the quality problems. Finally, some solutions are proposed.

1. The head of the screw is deformed and the head is snoring. The possible cause is a poor installation of the screw mold and improper adjustment.

2. The head of the screw is not round. The reason is that the selection of the die of the screw die is not good or the punching is not full enough.

3. The screws have burrs or burrs. The reason is that the die is poorly formed, mainly because the gap between the punch and the die hole is too large or the punch is too short.

4. The head of the screw is cracked and the head of the screw is cracked. The reason may be that the quality of the screw wire itself is problematic, so the screw wire must be inspected by the quality department before starting the test. Especially for stainless steel screw wire, it is necessary to check out that it is stainless steel 201, which is stainless steel 304. It is also possible that a die is used incorrectly (such as a die with a hexagonal head of the disk) and the viscosity of the lubricant is invalid. For the problem of the screw head, you can read the article written by Manager Zhu above - high-strength screw fracture or head crack detection. In this article, it is very clear to introduce some problems encountered in the screw head and how to detect the screw head problem.
