Increased Stripping Torque - Eliminate
Stripping
This new Shakeproof feature, a series
of "nibs" under the screwhead eliminates
amny screw stripping problems. The
nibs absorb excessive driving torque
and act asbrakes for the screw, generally
more than doubling stripping torque

settings and eliminate overstressing
of the inner panel. Recommended head
styles are Truss, Pan and Hexagon washer
heads. Dimensions are standard in all
cases.
