Wrenches Wera Joker 8 mm Stainless Steel Chromium-Molybdenum

Wera Joker combination ratchet wrench, 8 mm, made from chrome-molybdenum steel with nickel-chrome coating and stainless-steel elements. The compact 144 mm wrench combines an open-ended jaw and a ratchet ring end in one tool, designed for use on hexagon socket screws, bolts and nuts. The tool features a holding function and enhanced geometry to reduce slipping and allow higher torque transfer while remaining suitable for confined working spaces.

Advantages

The replaceable metal plate in the jaw secures nuts and bolts with hardened teeth to reduce the risk of dropping and slipping. An integrated limit stop prevents the wrench from sliding off the bolt head, enabling safer application of torque. The double-hex geometry ensures a positive fit on fasteners and the 80-tooth fine-tooth ratchet at the ring end allows work with a small return angle of 30°, minimising the need to flip the wrench. The forged geometry and chrome-molybdenum construction with nickel-chrome finish provide high strength and corrosion resistance. Colour coding on the tool finder helps with quick size identification.

Suitable for

• Assembly and maintenance of machinery and equipment with 8 mm hex fasteners
• Automotive and bicycle repairs where access is restricted
• Workshop and industrial applications requiring reliable torque transfer

How to use

Place the open jaw or the ring end over the 8 mm hex fastener and apply steady torque. Use the holding function in the jaw to retain nuts or bolts when positioning or starting threads. For confined spaces, use the 80-tooth ratchet ring to work with small back-and-forth movements; the 30° return angle at the open end reduces the need to reposition the wrench frequently. Replace the metal jaw plate if worn to preserve the holding and anti-slip properties.

Usage recommendations

Inspect the tool before use for wear on the jaw plate and ratchet mechanism. Do not exceed recommended torque for the fastener or apply impact loads. Store the wrench dry to maintain the nickel-chrome corrosion protection.
