Made for fast, easy access, the 12-point opening smoothly slides onto hex-shaped fastener heads at twice as many angle positions as 6-point sockets—every 30 degrees instead of every 60 degrees.
A shallow well and slim walls allow extra clearance for fitting into tight, narrow spaces.
Detent notches inside the drive end securely locks socket onto ratchets and extensions, so it won't fall off or stick on fastener heads.
