Adjustable Flat Wrench Joker 19-24mm

The Wera Joker 05020104001 is a high-performance adjustable flat wrench designed for professional use. Its self-setting jaw automatically adjusts to the fastener size between 19 and 24 mm, eliminating the need for manual adjustment.

This wrench features a hold-open mechanism that keeps the jaw open for easy repositioning on the fastener. The chrome-vanadium steel construction ensures durability and long life, with a matt chrome-plated finish that resists corrosion. The ergonomic handle design provides a comfortable grip, reducing hand fatigue during extended use. Ideal for automotive, industrial, and maintenance applications.
