Frequently Asked Questions

What is the PROTO J1131 box end wrench used for?

The PROTO J1131 is a SAE double-end, 12-point box end wrench used for tightening or loosening fasteners in industrial maintenance, automotive repair, and assembly applications. Its 15° offset head provides clearance over obstructions, making it suitable for confined spaces where a standard wrench cannot fit.

What are the specifications of the PROTO J1131 wrench?

The PROTO J1131 is a 6-inch overall length, double-end box end wrench with 3/4 in and 5/8 in head sizes. It has a 12-point, non-ratcheting box end, a satin finish, and a 15° offset head angle. It is designed for SAE fasteners and is manufactured by PROTO.

How to select the correct PROTO box end wrench size?

To select the correct PROTO box end wrench, match the wrench head size to the fastener hex size. For the J1131, use the 3/4 in end on a 3/4-inch hex nut and the 5/8 in end on a 5/8-inch hex nut. Ensure the 12-point box end fits securely over the fastener to prevent rounding.
