Works on rubber, plastic, vinyl, wood, leather or acrylics. The Stanley 92-824 Black Chrome and Laser Etched Socket Set includes 69 pieces that meet or exceed the American National Standards Institute (ANSI) specifications for combination wrenches, sockets, and ratchets. The laser etched sockets provide hi-visibility markings, making it easier to read compared to standard marked sockets. Black chrome offers a sharper appearance and better corrosion resistance when compared to regular chrome sockets. An easy reassemble of the lid to the case provides for convenient tool storage and travel. About Stanley Sockets and Ratchets Stanley sockets feature the proprietary Max-Drive design, a unique radius corner design which provides 15 percent more torque, making it easy to tighten fasteners and simplifies the turning of rounded corners. This technology helps reduce fastener wear without contact on the outer 5 percent of the fastener, so fasteners last longer. This helps reduce slipping on frozen or rusted fasteners. Stanley sockets are manufactured worldwide with high alloy steel and heat treated for performance. Stanley ratchets and accessories are designed to meet or exceed ANSI specifications. All are forged from high-quality steel and finished in high-polish chrome. Selected Stanley high-torque ratchets have a Quick Release mechanism for one-handed use. Sockets and extensions remain locked onto the drive until disengaged with an easy-to-reach, low-profile quick-release button. Stanley Pear Head Ratchets have a slim profile and a small 7-degree arc-swing for accessing hard to reach fasteners.
