scope:
GENERAL Penetration gaging provides a means for determining suitability of the 6-lobed sockets formed in the heads of screws to accept and conform with mating driving tools for the depth of engagement considered necessary to develop tensional characteristics adequate to properly tighten the screws. The use of screws having too shallow penetrations could result in production problems such as reaming of sockets or excessive wear on driver bits.
