Why can’t the low head socket cap screws be used?

When using low head socket cap screws, we sometimes find that screws are always unusable for some reason. Why?

The low head socket cap screws slip. This is generally because of the groove type of the screw. One is that the size of the groove is too small, and the other is that the depth of the groove is not deep enough, too shallow so that the screw cannot be used to screw the screw when screwing, so Slip. This is the two common reasons why screw slippage is common.

The appearance of the screw is a problem. Because of the use of the product, some low head socket cap screws are used as appearance parts. The problem with the appearance of the screws is that the color of the plating is not uniform, which makes it seem uncoordinated after assembly. The surface of the screw is scratched, etc., which causes the surface of the screw to be not smooth. This is generally caused by the collision of the screws on the way of transportation, which causes traces on the surface of the screw. Another situation is that during the production, because the mold is forming the screw, There are iron filings, notches, etc. on the mold, which will cause the screws to be produced on the surface.
