Proto J1192-A Box End Wrench 3/8 X 7/16 in 6 Pt Double End

Product Description

The PROTO J1192-A is a double-end ratcheting box end wrench sized 3/8 inch by 7/16 inch with 6-point geometry on both heads. The 6-point design grips fastener flats rather than corners, reducing the chance of rounding under high torque. Ratcheting box ends allow the technician to drive fasteners without breaking the wrench free from the fastener on each stroke, which speeds work in tight quarters. Constructed from steel, the wrench is built for repeated use in demanding trade environments. At 0.18 pounds, it is a lightweight hand tool suited for everyday carry in a tool pouch or box.

This wrench is used across HVAC, plumbing, electrical, and general mechanical service work wherever 3/8 inch or 7/16 inch hex fasteners are encountered. Typical applications include equipment panel removal, component mounting hardware, and service access covers. The double-end configuration provides two commonly paired SAE sizes in a single tool, reducing the number of pieces a technician needs to reach for during a service call.

• Ratcheting action drives fasteners without repositioning the wrench on each stroke

Compatibility

Designed for use with standard SAE hex fasteners in 3/8 inch and 7/16 inch sizes across residential and light commercial mechanical service applications.

Installation Notes

This wrench is a general-purpose hand tool used by HVAC technicians, plumbers, electricians, and mechanical service professionals. Always ensure the correct size head is fully seated on the fastener before applying torque to avoid fastener damage. De-energize and lock out equipment before loosening or tightening fasteners on live systems. Inspect the ratcheting mechanism periodically for wear and clean debris from the box ends to maintain proper engagement.
