Proto JSBV0709 Double End Box Wrench 7/32 X 9/32 in 12 Pt

Product Description

The PROTO JSBV0709 is a double-end box wrench designed for fastener work in tight spaces where an open-end wrench cannot seat properly. Built from steel with a chrome finish, it features 12-point box ends sized at 7/32 inches and 9/32 inches. The 12-point configuration allows engagement at 30-degree increments, which is useful when swing arc is limited. This wrench is reversible, meaning either end can be flipped and re-engaged without removing it from the fastener. Weighing 0.08 pounds, it is a compact hand tool suited for precision mechanical, HVAC, plumbing, and electrical service work where small fastener sizes are common.

This wrench fits applications where 7/32-inch or 9/32-inch hex fasteners are used. Common scenarios include servicing small equipment components, control panel hardware, and mechanical assemblies in residential and light commercial systems. Its compact size and dual-end design make it a practical addition to a service technician's hand tool set when working on smaller fasteners that standard combination wrenches may not reach cleanly.

Installation Notes

Hand tools like this wrench require no installation. Before servicing any equipment fasteners, de-energize electrical systems per NEC guidelines and shut off fluid supply lines as applicable. Use the correct end size to ensure full fastener engagement and avoid rounding. Inspect the wrench for cracks or finish damage before use on torque-sensitive fasteners.
