The most commonly used sockets are 12 point because they are easier
to position for rapid seating on hex or 12 point fasteners. Proto's
TORQUEPLUS design further improves the efficiency of the 12 point
design. Proto's 6 point sockets, also incorporate TORQUEPLUS™ are
often used on stubborn or worn hex bolts, or bolts made from a soft material.
Proto hand sockets incorporate the TORQUEPLUS™ wrenching system.
This high performance design allows the socket to contact the fastener
away from the corner while also dispensing stress over a large area.
TORQUEPLUS™
Allows up to 15% more torque to be applied to the fastener.
Reduces the risk of fastener rounding.
Provides a greater opportunity to turn worn, rounded fasteners.
Sockets incorporating TORQUEPLUS are identified in each
individual product section.
Standard length sockets are the most commonly used length because
they are more suited for close, confined areas. Deep sockets are used
to accommodate nuts where bolts protrude or to access a fastener in a
recessed area.

1/4" to 1" drive, that accommodate a fastener sizes of 1/16" thru 3-1/2"
