What is the effect of head blasting on knurling molding of m5 knurled thumb screws?

Headshot, for people unfamiliar with the screw industry is incomprehensible. A headshot is a crack in the head of a molded screw. So what is the impact of head blasting on the forming of m5 knurled thumb screws?

m5 knurled thumb screws knurling molding generally has two kinds, one is through CNC turning processing. The screw produced in this way will not have a headshot. Another method of production is cold heading. The flat head is produced by cold heading, and the knurled head is produced by twisting. If it is cold heading production, there will be a head explosion. If the flat head produced has a head explosion, it will not be able to make knurled flowers when rubbing.

So in the production of screws why will there be a head shot? One is wire problem, 2 are adjustment machine problem, 3 are punch to have a problem. If there is a headshot in production, it should be solved according to the actual situation.

If you also want to order m5 knurled thumb screws, or other types of screws, such as long screws, shoulder screws, small screws, non-standard screws, titanium screws, please contact Shi Shi Tong screw manufacturers.
