Hex and Ball-End L-Key Set Bondhus BO22199 — combination of 12199 and 12137 sets

Bondhus BO22199 is a combined L-key set that brings together two factory sets of hex and ball-end L-keys to cover a broad range of metric sizes for general mechanical, assembly and maintenance work. The set includes standard straight hex ends for secure engagement and ball ends for angled access in confined or hard-to-reach locations. Made to provide consistent fit, torque transfer and durability, the set is intended for professional and home workshop use where multiple sizes are required in one compact kit.

Advantages

The combination of straight hex ends and ball-end geometry allows both precise, full-depth engagement and flexible angled insertion up to approximately 25–30 degrees, reducing the need to reposition workpieces. Hardened steel construction and a finish designed to resist corrosion ensure long-term performance. The set’s organized arrangement simplifies size selection and storage while delivering reliable torque transmission and minimized fastener rounding when used correctly.

Suitable for

• Tightening and loosening hex fasteners in machinery and equipment maintenance
• Assembly work on furniture, bicycles, and metal frames
• Service and repair tasks in workshops and production lines
• Accessing fasteners in recessed or angled locations where straight entry is limited

Key specifications

• Includes both straight hex ends and ball ends for angled engagement
• Comprehensive range of metric sizes from two combined factory sets
• L-shaped keys for increased leverage and reach in confined spaces
• Hardened steel construction for strength and wear resistance
• Protective finish to reduce corrosion and extend service life
• Compact, organized storage for easy size identification and transport

How to use

Select the L-key size that matches the hex fastener head for a snug fit to avoid rounding. For maximum torque and precise control, insert the straight hex end fully into the fastener and apply steady force using the long leg of the L-key. When access is obstructed, use the ball end to engage the fastener at an angle; ensure sufficient engagement depth to prevent slippage. Keep keys clean and inspect tips for wear; replace any keys with rounded or damaged ends to maintain safe operation.

Usage recommendations

Use the straight hex end for high-torque operations and the ball end for situations requiring angled access. Avoid using excessive force or cheater bars on the L-keys to prevent bending or tip damage. Store keys in their organizer to protect tips and maintain size order.
