The Stanley 92-804 30 Piece Socket Set are forged from high-quality steel and finished in high-polish nickel chrome. The ratchet handles are ergonomically designed and have an easy-to-use, thumb-operated reverse-switch mechanism. The sockets and extensions remain locked onto the drive until disengaged with an easy-to-reach, low-profile quick-release button. Stanley sockets feature our Max-Drive design, a unique radius corner design that provides 15% more torque than standard sockets to tighten fasteners easily and simplify the turning of rounded corners. Max-Drive helps reduce fastener wear by minimizing contact on the outer 5% of the fastener, helping to increase life expectancy than standard sockets, and Max-Drive helps reduce slipping on frozen or rusted fasteners. All Stanley ratchets, sockets and wrenches are manufactured globally to Stanley specifications, meeting and often exceeding ANSI specification. Includes: (27) 1/4″ Drive Sockets, (1) 1/4″ Drive Universal Joint, (1), 1/4″ Drive Extension bar – 3″, (1) 1/4″ Pear Head Ratchet, Blow Molded Case.
