Bahco BE-9770 set imbus ključeva u obliku slova L

The L-shaped hex key set Bahco BE-9770 is a compact 9-piece metric offset long series with ball end hexagon keys finished in black. Designed for access in confined or recessed areas, each L-shaped key offers an extended reach on one side and a short handle on the other for greater torque control. The ball end enables angled engagement when a straight entry is not possible, expanding the range of usable positions. The set is lightweight and comes as a coordinated group of sizes to cover common metric fasteners.

Advantages

The set combines long reach and offset geometry to reach fasteners in narrow or obstructed locations while preserving hand clearance. The ball end design permits approach angles up to approximately 25–30 degrees, allowing work where straight insertion is impeded. A black finish improves corrosion resistance and provides a uniform appearance. The complete 9-piece assortment reduces the need to mix different tools, and the total weight supports easy handling and transport.

Suitable for

• Assembly and maintenance of machinery and equipment in confined spaces
• Bicycle, automotive and household repairs requiring angled access
• Electronics enclosures and furniture assembly where clearance is limited
• Professional workshops and DIY projects that use metric hex fasteners

Key specifications

• Number of pieces: 9 metric keys
• Design: L-shaped (offset) with long arm and short arm
• Tip type: ball end on long arm, standard hex on short arm
• Finish: black protective coating
• Weight: approximately 355 g for the full set

How to use

Select the hex key size that matches the fastener head and insert the short arm for maximum torque or the long arm for extended reach. For angled approach use the ball end on the long arm, ensuring engagement depth is sufficient to avoid rounding the fastener. Apply steady, even force and avoid sudden high torque on the ball end to prevent deformation. Store the set together to keep sizes organized and to prevent loss.

Recommendations

Use the short arm when higher torque is required and the long arm with ball end for access at angles; avoid using the ball end as the primary high-torque driver. Keep keys clean and lightly oiled if exposed to moisture to maintain the black finish and prevent corrosion. Match key size precisely to fastener to minimize wear.
