Built around a 1\/4 inch drive, it accepts standard 1\/4 inch drive sockets and delivers a maximum torque output of 60 ft-lb. The shank measures 0.425 inches in diameter and uses a J-type shank configuration for secure attachment to a compatible torque wrench handle. This head is rated for SAE fastener applications and is sold individually. Mechanics, HVAC technicians, and industrial maintenance professionals install this type of head when a low-profile or dedicated ratcheting torque wrench setup is required for confined or repetitive fastening work.\u003c\/p\u003e\u003cp\u003eThis torque wrench head is suited for use in residential and light commercial maintenance, HVAC equipment service, refrigeration system assembly, and general mechanical applications where controlled torque is required.
