05003760001 Wrench double open end 10/13 Joker

This Wera Joker double open-ended wrench is a specialized bit of kit designed for 10mm and 13mm bolts and nuts. Unlike standard wrenches, the Joker uses a 12-point beak design that allows for a 30-degree pivoting angle, making it much easier to use in cramped spaces where a traditional 60-degree turn isn't possible. It features a clever metal limit stop plate that prevents the wrench from slipping off the fastener head and can even hold a nut in place for you. The hardened, serrated edge on the plate provides extra grip on stubborn or rounded fasteners. This tool measures 167mm in length, is color-coded for size, and is sold as a pair.
