Here you'll find a wide selection of Sockets and Accessories from Stanley® Proto®. The most commonly used sockets are 12-pointbecause they are easier to position for rapid seating on hex or 12-point fasteners. 6-Point sockets are often used on stubborn or worn hex bolts, or bolts made from a soft material. Standard length sockets are the most commonly used length because they are best suited for close, confined areas. Deep sockets are used to accommodate nuts where bolts protrude or to access a fastener in a recessed area.
