#4 x 1" Torq-Set Driver Bit Wire Detent

You have probably seen Torq-Set bits without realizing it. While they look like a misshapen Phillips recess, they are actually used extensively in the aviation industry, and occasionally show up on industrial products as well. If you happen to be an aviation mechanic, these are the bits you need - otherwise, when you run into a fastener with a Torq-Set recess, remember that we carry the bits.
