L-shaped hex key Wera 950 BM, metric, single piece, long arm 5.6 cm, short arm 1.8 cm

Wera 950 BM is a single-piece L-shaped metric hex key engineered for driving internal hex fasteners. The tool features a long arm of 5.6 cm and a short arm of 1.8 cm, offering a compact combination of reach and torque for work in confined spaces. Designed with Hex-Plus geometry, the key increases contact area within the screw head to reduce rounding and minimize damage to the recess. A BlackLaser surface treatment enhances corrosion resistance and extends service life, while wear-resistant size markings allow quick identification.

Advantages

The Hex-Plus profile provides improved engagement with hex socket screws, reducing notching and preserving screw integrity. The single-piece L-shape delivers predictable torque and access from either arm. BlackLaser surface treatment offers durable protection against corrosion and wear, helping maintain functional appearance and performance. Clearly stamped size markings are wear-resistant for rapid tool selection.

Suitable for

• Assembly and disassembly of machinery components where compact access is required
• Maintenance and repair of electronics and appliances with internal hex fasteners
• Furniture assembly and adjustment in tight or recessed locations
• General workshop tasks requiring a durable metric hex key

Key specifications

• Design: single-piece L-shaped hex key
• Metric size: Hex-Plus geometry for improved contact
• Long arm length: 5.6 cm
• Short arm length: 1.8 cm
• Surface finish: BlackLaser treated for corrosion resistance
• Markings: wear-resistant size markings

How to use

Select the correct metric key size and insert the short or long arm into the internal hex screw recess until fully seated. Use the long arm for reach and the short arm to apply higher torque as needed. Maintain axial alignment while turning to ensure full contact between the Hex-Plus profile and the screw recess; avoid using excessive force that could damage the fastener or tool. After use, store the key in a tool holder or set to protect the finish and markings.

Usage recommendations

For best results, use the long arm when accessing recessed screws and the short arm when higher torque is required. Clean mating screw recesses of debris before use to maximize contact and reduce wear. Avoid using the hex key as a pry bar or hammer to preserve its shape and the integrity of the Hex-Plus profile.
