The importance of Recess Gaging in the Fastener Industry

Have you ever tried to drive a screw in a deck board only to get three-quarters of the way down and suddenly strip out the recess with the driver bit? If so, you are dealing with either a poor-quality recess or a poor-quality driver bit.

There are several potential reasons for poor-quality recesses or driver bits.

1. Poor metallurgical properties of the recess or driver bit
2. A recess that was not formed properly
3. A gage that is out of its specification therefore not in conformance to its design intent
4. A driver bit that is not formed properly
