Wera Joker Switch schroefsleutel-/dopsleutelset

Wera Joker Switch Set — a high-quality 5-piece set of ratcheting combination wrenches designed for secure gripping and efficient work. The set includes sizes 10 mm, 13 mm, 17 mm, 19 mm and a 1/4" drive, combining an angled ratchet head with a reversible ratchet mechanism and an exchangeable metal plate in the jaw to hold nuts and bolts firmly. Forged from chrome‑molybdenum steel with a nickel‑chromium coating, these wrenches offer high torque transfer, good flexural rigidity and corrosion resistance while keeping a compact footprint for easy handling and storage.

Advantages

The Joker ratcheting combination wrenches feature an angled 15° ratchet end and a 30° low return angle at the jaw to minimize flipping and improve access in confined spaces. An exchangeable hardened metal plate in the jaw with extra hard teeth and a double-hex geometry provide secure holding and reduce slipping. The reversible ratchet mechanism with 80 fine teeth gives audible and precise engagement, while a robust two-piece locking element increases stability. Colour-coded sizes (Take it easy Tool Finder) simplify identification.

How to use

Select the correct size wrench for the nut or bolt to avoid rounding. Place the jaw with the exchangeable metal plate over the fastener to engage the double‑hex geometry, then use the ratchet end or the jaw side as required. For confined spaces use the reversible ratchet mechanism with its fine toothing; use the 15° angled end to increase access. Apply torque steadily and avoid sudden impacts to preserve the hardened teeth in the exchangeable plate.

Recommendations

Inspect the exchangeable metal plate periodically for wear and replace it if teeth are damaged. Store the wrenches dry and clean to maintain the nickel‑chromium corrosion protection and use the colour coding to quickly pick the correct size.
