Combination wrench Wera Joker 17 mm, length 190 mm, 1 piece

Wera Joker combination wrench 17 mm, 190 mm length, single piece. This combination wrench offers an open-end mouth and an angled box-end in a compact 190 mm body designed for workshop and field use. The Joker geometry with a 7.5° pivoted mouth and double-hexagon ring expands placement options in confined spaces, enabling precise engagement of bolts and nuts where access is limited. The slim ring side is angled by 15° to the tool axis, and the tool features a durable surface treatment for long-lasting corrosion protection. The wrench is colour-coded by size for quick identification.

Advantages

The special mouth geometry increases the number of placement points, allowing the wrench to engage fasteners every 15° and to find the correct seating automatically after turns. Its low return angle and double-hexagon ring make work in tight installation spaces more efficient by reducing the need for repositioning. The slim, angled ring end improves access to recessed or closely packed fasteners, while the compact 190 mm length balances reach and control. The corrosion-resistant finish preserves functionality and appearance under regular use.

Suitable for

• Automotive maintenance and repair tasks requiring a 17 mm wrench
• Mechanical assembly where access is limited or confined
• General workshop and field service work on bolts and nuts
• Situations that demand quick tool identification and size sorting

How to use

Position the open end or the box end on the 17 mm nut or bolt head so the wrench fully seats on the flats. For confined spaces, use the pivoted mouth and ring geometry to engage the fastener at the available angle; repeated 180° turns around the tool axis provide multiple placement points and allow incremental rotation every 15°. Apply steady, controlled force to avoid slipping and ensure full contact between the tool and fastener. After use, clean any debris and store the wrench in a tool roll or holder to maintain the surface treatment.

Usage recommendations

Use the box end where possible for higher torque and reduced risk of rounding fasteners. Avoid using the wrench as a hammer or pry bar. Inspect the contact faces regularly for wear; replace the tool if the mouth or ring shows deformation that could compromise secure engagement.
