Stanley STMT73338-8B 1/2 Inch Drive 6-Point Deep Socket 27 mm

Sized at 27 mm, the Stanley STMT73338-8B is a 6-point deep socket for 1/2-inch drive ratchets and handles. A deep socket has a longer body than a standard one, so it slides over protruding bolt threads to reach the nut. Stanley uses chrome vanadium steel and its Maxi-Drive radius corners, which it says give 15% more torque than standard sockets and help reduce fastener rounding. Stanley lists ASME B107.5M, DIN 3124, ISO 1174-1, ISO 1711-1 and ISO 691, marks it as exceeding the ANSI standard, and makes it for hand tools rather than impact drivers. The range covers 17 sizes, 10 mm to 32 mm.
