Combination Wrench Wera 05020091001

Combination Wrench Wera 05020091001 is an 11-piece set of high-quality Joker ratcheting combination wrenches with sizes from 8 to 19 mm and an additional 1/4" imperial size. Each wrench features an angled ratchet head with a switch lever and an exchangeable metal plate in the jaw that securely holds nuts and bolts. The tools are forged from chrome-molybdenum steel with a nickel-chromium coating for enhanced corrosion protection and durability.

Advantages

The integrated limit stop and extra-hard teeth on the exchangeable jaw plate reduce the risk of slipping and losing fasteners while allowing higher torque application. Double-hex geometry provides a positive connection with fasteners and further reduces slipping. A low return angle of 30° at the jaw end minimizes flipping during operation. The reversible ratchet mechanism at the ring end has fine 80-tooth toothing for use in confined spaces and operates with audible precision. A robust two-piece locking element increases stability, and a 15° angled ratchet end supports secure work under high torque. Colour coding according to size simplifies tool identification.

Suitable for

• Tightening and loosening metric and 1/4" imperial nuts and bolts (sizes 8–19 mm and 1/4")
• Mechanical and automotive maintenance in confined spaces

How to use

Select the correct wrench size for the nut or bolt. Place the jaw over the fastener and, if needed, engage the exchangeable metal plate to hold the nut securely. Use the angled ratchet head and switch lever to apply torque in the desired direction; the reversible 80-tooth ratchet at the ring end enables incremental movements in confined spaces. For high-torque tasks, use the 15° angled ratchet end and ensure the integrated limit stop is positioned to prevent downward slipping. After use, store the wrenches by size using the colour coding for quick identification.

Usage recommendations

Use the correct size to avoid rounding fastener heads. Inspect the exchangeable jaw plates before use and replace if worn. Apply torque within the tool's intended range and avoid using the wrenches as hammers or pry bars to maintain performance and safety.
