Wera 05020203001 Combination Wrench 12mm

Product Description

The WERA 05020203001 is a 12mm combination wrench designed for professional fastener work in mechanical, HVAC, plumbing, and electrical trade applications. Built from alloy steel with a satin finish, this non-ratcheting wrench features a 12-point box end and an open end in a single tool. The satin finish reduces glare in bright work environments and resists corrosion under typical shop and field conditions. At 0.58 pounds, it is a solid, hand-feel tool sized for M12 fasteners. WERA backs this wrench with a lifetime warranty.

This wrench is suited for residential and commercial service work where M12 fasteners appear on equipment panels, bracket hardware, pipe hangers, conduit fittings, and mechanical assemblies. It performs in both tight cabinet access and open bench work. The 12-point box end provides more engagement positions than a 6-point profile, which is useful when swing arc is limited. It is a standard addition to a journeyman or service tech tool kit.

Installation Notes

No power shutoff is required for wrench use, but always de-energize electrical panels and shut off gas or water supply before servicing any equipment the wrench is applied to. Use the correct size wrench to avoid rounding fastener heads. Inspect the wrench for cracks or deformation before each use and remove it from service if damaged.
