L-shaped hex key Wera 950 BM, metric, 1 pc — long arm 8 cm, short arm 2.8 cm

Wera 950 BM is a single-piece L-shaped metric hex key designed for accurate engagement with hexagonal socket screws. The tool has a long arm of 8 cm and a short arm of 2.8 cm to balance reach and leverage for tightening and loosening fasteners in both confined and open spaces. Manufactured with Hex-Plus geometry to increase contact surface inside the screw head, the key reduces notching effects and lowers the risk of damaging screw recesses. A BlackLaser surface treatment improves corrosion resistance and overall durability, while wear-resistant size markings make it easy to select the correct key.

Advantages

The Hex-Plus profile increases contact area in the screw recess, which reduces wear on both tool and fastener compared with conventional hex keys. The two-arm L shape gives a choice of working lengths for torque or reach: the 8 cm long arm provides greater reach and leverage, and the 2.8 cm short arm offers access in tight spots. BlackLaser surface treatment protects against corrosion and extends service life. Visible, wear-resistant size markings enable quick identification of the tool.

Suitable for

• Assembly and disassembly of metric hex socket fasteners in furniture, machinery and equipment
• Maintenance tasks where access to recessed or hard-to-reach hex sockets is required
• Workshop and service environments that require reliable torque transfer and reduced screw damage
• Precision tightening tasks where controlled leverage and accurate engagement are important

How to use

Select the L-shaped hex key that fits the metric hex socket you intend to turn. Insert the short or long arm into the fastener depending on required reach and torque: use the long arm for higher leverage and the short arm for access in confined spaces. Apply steady, controlled force to avoid cam-out; the Hex-Plus geometry helps distribute load across a larger contact area. After use, clean any debris from the tool and fastener and store the key in a tool holder or toolbox to protect the BlackLaser surface.

Usage recommendations

For best results, use the correct-sized metric key to avoid rounding the screw recess. When working with rusted or heavily torqued fasteners, apply penetrating lubricant and allow time to work before turning. Store the key dry and clean to preserve the BlackLaser coating and markings.
