FOR 1" SQ. DRIVES
Bolt Clearance depth: 4 inches. Bronze socket sizes available in hex or 8-pt. styles, from 1-5/16" to 1-7/8". Made for 1" square drive wrenches.
Do not use impacting wrenches with bronze sockets. Use hand wrench only. Limit torque (non-impacting) to 500 ft/lbs.
Service life of bronze sockets is indeterminate: it is based on torque applied, frequency of use, and whether wrench drive is secured in socket with a locking pin. Because bronze is a soft metal it is spark-resistant, but has a shorter service life than steel.
