Proto J3070 Open End Wrench 1-1/2 X 1-5/8 in Double End Steel

Product Description

The PROTO J3070 is a double-ended open end wrench designed for heavy-duty fastener work in trade and industrial environments. Built from steel with a satin finish, it spans two wrench sizes — 1-1/2 inches and 1-5/8 inches — on a single tool, reducing the need to swap wrenches mid-job. The 15-degree head angle positions the handle clear of obstructions, giving technicians leverage in tight or cluttered work areas. It meets ASME B107.6 and federal specification GGG-W-636E standards. Plumbers, pipefitters, HVAC mechanics, and millwrights working on large-diameter fasteners and fittings will find this wrench suited to their needs.

The J3070 is appropriate for applications involving larger fasteners commonly found in commercial HVAC equipment, large pipe flanges, industrial machinery mounts, and structural connections. The dual-size configuration makes it a practical carry tool when working on equipment where both 1-1/2-inch and 1-5/8-inch hardware appear in the same assembly. The satin finish reduces glare in bright work environments and provides a degree of corrosion resistance for shop and field use alike.

Installation Notes

This wrench is a hand tool and does not require installation. Inspect the wrench openings before each use to confirm no deformation or wear that could cause slippage on fasteners. Do not use extensions on the wrench handle to increase torque beyond the designed capacity of the tool. Store in a dry environment to preserve the satin finish.
