## Summary description

Bondhus BO10660 is a 4 mm hex (Allen) L-key screwdriver featuring a ball end for angled engagement. Designed for fastening and loosening hex socket fasteners where access is limited, the ball end allows entry at an angle and improved maneuverability. Suitable for workshop, maintenance, and repair tasks on machinery, furniture, and bicycles.

## Long description

Bondhus BO10660 — 4 mm with Ball End is a hex L-key screwdriver designed for fastening and loosening hex socket fasteners in confined or awkward positions. The 4 mm hex shaft provides a precise fit for compatible fasteners, while the ball end permits engagement at an angle for access where a straight approach is impossible. This tool is made for routine workshop, maintenance and repair tasks on machinery, furniture and bicycles where reliable torque transfer and improved clearance are required.
Advantages
The L-shape gives leverage for turning and a short end for access in tighter spaces, while the ball end increases operating angles without slipping from the socket. The solid hex geometry ensures accurate contact with fastener faces to minimise rounding. The compact profile is convenient to carry in a toolkit or pocket and to use in confined assemblies.
Suitable for
 Fastening and loosening 4 mm hex socket bolts and screws
 Maintenance and repair of bicycles, small machinery and furniture
 Working in confined or angled access points where straight entry is restricted
 General workshop and field service kits requiring a reliable Allen key
When it may not be suitable
This 4 mm L-key is intended for hex socket fasteners of the corresponding size; it is not suitable for bolts or screws with rounded or damaged heads where extraction requires specialised tools. The ball end provides angular access but reduces the maximum torque that can be safely applied compared with a full straight engagement, so it may not be appropriate for heavily tightened or high-torque fasteners.
Key specifications
 Hex size: 4 mm
 Type: L-key (Allen key) with ball end
 End style: Ball end for angled engagement
 Primary uses: Fastening and loosening hex socket fasteners in confined spaces
 Form factor: Compact L-shaped tool for leverage and reach
How to use
Insert the 4 mm end into the hex socket of the fastener. For higher torque, use the long arm as a lever and the short arm for access in tight spaces. To operate at an angle, seat the ball end into the socket and apply steady turning force while maintaining contact; avoid using excessive force when using the ball end to prevent rounding. Inspect the fastener head and tool engagement before applying full torque to ensure a secure fit.
What to consider before purchase
 Confirm fastener size is 4 mm hex to ensure compatibility
 Consider whether angled access is needed; ball end enables this but limits maximum safe torque
 Check that a single L-key meets your kit needs or if a set with multiple sizes is preferable
Usage recommendations
Use the short arm for access and the long arm for leverage; prefer straight engagement for high-torque jobs and use the ball end for initial positioning or when clearance prevents straight entry.
