Llave Wera Joker Switch 19

The Wera Joker Switch 19 is a ratcheting combination wrench with an angled ratchet head and switch lever, designed for reliable fastening of 19 mm fasteners. Its exchangeable metal plate in the jaw with extra-hard teeth and double-hex geometry provides a secure hold on nuts and bolts and reduces the risk of slipping. The tool is forged from chrome-molybdenum steel with a nickel-chromium coating for corrosion resistance and features Wera's colour coding system for easy size identification.

Advantages

The integrated limit stop prevents slipping off the bolt head and allows higher torque application. The low return angle of 30° at the jaw end minimises flipping of the wrench in confined spaces. The reversible ratchet mechanism at the ring end has fine 80-tooth toothing for flexible work in tight areas and an audibly precise action. A robust two-piece locking element increases stability, while the 15° angled ratchet end supports secure operation at high torque.

Suitable for

• Fastening and loosening 19 mm nuts and bolts
• Work in confined or hard-to-reach spaces
• Applications requiring high torque transfer and reduced slipping

How to use

Select the 19 mm Joker Switch wrench and position the jaw or ring end on the fastener. Use the switch lever to set the ratchet direction and apply torque through steady pressure. The exchangeable metal plate in the jaw holds the nut or bolt while the integrated limit stop reduces the risk of slipping. For work in tight spaces, use the ring end with the fine-toothed reversible ratchet and take advantage of the 30° return angle to minimise repositioning.

Recommendations

Inspect the exchangeable metal plate and the ratchet mechanism regularly for wear. Replace the metal plate if the teeth are worn to maintain secure holding. Clean and lightly lubricate the ratchet mechanism when necessary and store the wrench dry to preserve the nickel-chromium coating and prevent corrosion.
