NoCoRode™ screws (those coated for added corrosion resistance) have significantly more plating on them than most other "corrosion resistant" screws.
While this provides more corrosion protection, it does reduce the screw's recess size. A standard #2 sized driver bit will not fully seat itself into a NoCoRode protected screw which can cause the bits to cam out or strip the recess.
These bits are designed with slightly smaller tips which fully seat themselves in NoCoRode coated screws.
