L-shaped hex key Wera 950 BM Metric, single piece, long arm 5 cm, short arm 1.6 cm

Wera 950 BM is an L-shaped metric hex key supplied as a single piece with a long arm length of 5 cm and a short arm length of 1.6 cm. Designed for working with hexagonal socket screws, this compact hex key combines a short overall size with sufficient leverage for small assemblies and confined spaces. The tool features Hex-Plus geometry for increased contact area with the screw head, and a BlackLaser surface treatment that improves corrosion resistance and durability. Size markings on the tool are wear-resistant for quick identification.

Advantages

The Hex-Plus profile reduces notching and lowers the risk of damaging the screw recess compared with conventional hex keys, improving fastener life. The BlackLaser finish offers enhanced surface protection and corrosion resistance while maintaining a low-friction surface for smoother insertion. Single-piece L-shape provides straightforward use in tight spaces and allows application of torque from either the long or short arm. Wear-resistant size markings enable rapid selection of the correct metric size.

Suitable for

• Precision maintenance and electronics where small metric hex fasteners are used
• Bicycle adjustments and small mechanical repairs
• Assembly and disassembly of compact devices and housings
• General workshop tasks requiring a compact metric hex wrench

Key specifications

• Tool type: L-shaped metric hex key, single piece
• Long arm length: 5 cm
• Short arm length: 1.6 cm
• Geometry: Hex-Plus profile for increased contact area
• Surface treatment: BlackLaser for enhanced corrosion protection
• Markings: Wear-resistant size markings

How to use

Select the correct metric size and insert the appropriate hex key arm fully into the hex socket of the fastener to ensure maximum contact. Use the long arm for increased leverage when loosening or tightening, and switch to the short arm for access in confined spaces. Apply steady, controlled torque to avoid overloading small fasteners. After use, wipe the tool clean and store it in a tool roll or holder to protect the BlackLaser surface and the markings.

Usage recommendations

For best results, use the Wera 950 BM hex key with matching metric hex fasteners only, avoid excessive torque beyond the fastener’s specifications, and keep the tool dry and clean to preserve the surface treatment and markings.
