Wrenches Set Wera Joker Set 4 pcs

Wera Joker Set 4 pcs is a high-quality combination ratchet wrench set containing four sizes: 10, 13, 17 and 19 mm. The set is supplied in a robust pouch and is designed for hexagon bolt heads and nuts. Each wrench features a replaceable metal plate in the jaw that holds nuts and bolts securely, an integrated limit stop to prevent slipping down the bolt head, and a double-hex geometry for a positive connection and reduced risk of rounding. The ring end uses an 80-tooth fine-ratchet mechanism for operation in confined spaces. Tools are forged from chrome molybdenum steel with a nickel-chrome coating for corrosion protection, and include Wera's colour-coded Tool Finder for quick size identification.

Advantages

The set provides a holding function that reduces the risk of dropping nuts and bolts and a replaceable extra-hard metal plate in the jaw for secure gripping. The integrated limit stop and double-hex geometry allow higher torque transfer with lower slipping risk. A 30° return angle at the open end minimises the need to flip the wrench while tightening, and the 80-tooth ratchet enables fine movement in tight spaces. Durable chrome molybdenum steel construction with nickel-chrome coating improves strength and corrosion resistance.

How to use

Select the wrench with the correct size for the hexagon bolt or nut. Position the open or ring end on the fastener and, if needed, use the holding function by engaging the metal plate in the jaw to secure the nut or bolt before lifting. Use the ratchet ring end to operate in confined spaces and apply steady torque while avoiding sudden impacts. Replace the jaw plate if worn to maintain secure gripping and inspect the tool for damage before use.

Usage recommendations

For long tool life and reliable performance, clean and lightly lubricate the ratchet mechanism periodically, store the wrenches in the supplied pouch, and avoid using the wrenches as hammers or pry bars. Replace the metal jaw plate if its teeth become worn to preserve the holding function.
