Summary of information:Why is there an R angle under the head of the hexagon head screw?

When we look at the underside of the head of the hexagon head bolt, we sometimes see a relatively obvious R angle, so why is there an R angle under the head of the screw? The following Yueluo editor will take you to see the specific situation.


The R angle is generally set under the head of the hexagon head bolt to protect the head of the screw from being broken when screwing. There is an R angle under the head. Generally, the diameter of the head is relatively large, and when the diameter of the rod is relatively large, it will be set; or the groove is a bit deep, in order to prevent the head from breaking during screwing, it will be set under the head. R angle, or change the thickness of the head of the screw, the size of the rod, etc.


But some customers feel that adding an R angle under the head makes it inconvenient for them to use it with the spacer. Because their spacers are purchased according to the standard size, and once the R angle is added under the head of the screw, there will be a mismatch when using it.


In this case, either change the inner diameter of the gasket, or do not use the gasket, or change the head to a belt, which can also save the gasket.
