Proto J3146 Open End Wrench 1-7/16 in Double End

Product Description

The PROTO J3146 is a double-ended open end wrench designed for professional-grade fastener work in mechanical, industrial, and maintenance applications. Built from steel with a chrome-plated finish, this wrench features a 1-7/16 inch opening and a dual head angle configuration of 15 degrees and 60 degrees, giving technicians two offset options in a single tool. At 14 inches in length and 1.35 pounds, it delivers solid leverage without excessive bulk. The chrome finish resists corrosion and simplifies cleanup in shop environments. This wrench meets GGG-W-636E federal standards and carries a lifetime warranty.

The J3146 is suited for heavy-duty fastener applications where a 1-7/16 inch open end is required. The dual-angle head design allows access to fasteners in tight or awkward spaces by switching ends rather than switching tools. Typical use cases include machinery maintenance, structural assembly, and industrial service work. The 14-inch handle provides the leverage needed for larger fastener sizes without requiring a breaker bar. Mechanics, millwrights, pipefitters, and general maintenance technicians will find this wrench fits standard workflow in both shop and field settings.
