Hex key set Wera L‑shaped with ball end 9 pcs 5/64"–3/8" (Wera 022171)

Wera L‑shaped hex key set 9 pcs with ball end provides a compact, practical selection of L‑type hex (imbus) keys in sizes from 5/64" to 3/8". Each key features a ball end on the long arm for access at angles and a straight short arm for high torque applications. The set is intended for fastening and loosening hex socket screws in mechanical, electrical and assembly tasks in workshops, service and maintenance environments.

Advantages

The ball end design enables operation at an angle up to about 25° from the axis, improving accessibility in confined spaces while preserving control. L‑shaped construction delivers a choice between reach and torque: use the long arm for reach and the short arm for greater leverage. The keys are made to provide precise fit and reduce rounding of fasteners, and the set covers a broad range of common imperial hex sizes for versatile use.

Suitable for

• Workshop repairs and maintenance
• Mechanical assembly and disassembly of machinery
• Electrical and electronic equipment service
• Automotive service tasks requiring compact hand tools
• On‑site service and installation work in confined spaces

Key specifications

• Tool type: L‑shaped hex keys with ball end
• Number of pieces: 9
• Size range: 5/64" to 3/8" (imperial sizes)
• Ends: ball end on the long arm, straight short arm for torque
• Material and finish: hardened steel construction for wear resistance (manufacturers' typical construction)

How to use

Select the hex key that matches the fastener size and insert the short or long arm squarely into the hex socket to ensure proper engagement. For limited‑access fastening, use the ball end at an angle up to approximately 25° to reach the screw head; for higher torque, use the short arm inserted with the long arm as a handle. Apply steady, controlled force and avoid excessive bending or leverage beyond the tool's intended capacity to prevent damage to the key or fastener.

Usage recommendations

Keep the keys clean and store them in their holder or a toolbox to prevent corrosion and loss. Inspect fastener fit before applying full torque and replace keys if any visible wear or deformation appears. Where precise torque is required, use a torque tool suitable for hex bits rather than relying solely on hand leverage.
