L-shaped hex key Wera 950 BM Metric, 1 pc, long arm 11.2 cm, short arm 4 cm

The Wera 950 BM Metric L-shaped hex key is a single-tool solution for driving metric hex fasteners. This model features a long arm of 11.2 cm and a short arm of 4 cm, offering a balance of reach and torque for a variety of assembly, maintenance and repair tasks. Manufactured with Wera's Hex-Plus geometry, the key increases contact area in the screw recess to reduce rounding and preserve fastener integrity. A BlackLaser surface treatment improves corrosion resistance and extends service life, while wear-resistant size markings allow quick identification.

Advantages

The L-shaped design provides leverage on the long arm and access in confined spaces with the short arm. Hex-Plus geometry minimises notching and reduces the risk of damaging screw heads compared with conventional hex keys. BlackLaser surface treatment protects against corrosion and wear, contributing to a longer usable life. The clearly marked size on the tool allows rapid selection and reduces downtime during tasks.

Suitable for

• Assembly and disassembly of machinery and equipment with metric hex fasteners
• Bicycle maintenance and repairs where space is limited
• Furniture assembly and household repairs
• Precision mechanical work and maintenance tasks requiring controlled torque

Key specifications

• Long arm length: 11.2 cm
• Short arm length: 4 cm
• Geometry: Hex-Plus for increased contact area in screw recesses
• Surface treatment: BlackLaser for enhanced corrosion and wear resistance
• Markings: Wear-resistant size markings for quick identification
• Material characteristics: hardened steel for durability and torque transmission

How to use

Select the appropriate metric size that matches the hex socket of the fastener. Insert the short or long arm into the screw head depending on required access and leverage: use the long arm for higher torque and reach, and the short arm for better access in tight spaces. Apply steady, even force and avoid excessive bending or levering outside the tool’s intended use. After use, wipe clean and store in a dry place to maintain the BlackLaser treated surface.

Usage recommendations

For best results, use the long arm to obtain higher torque when loosening or tightening larger screws and the short arm when working in restricted areas. Regularly inspect the hex tip for wear before use; replace the key if rounded edges appear to prevent damage to fastener heads.
