Hex key (inch) Bondhus 1/2" ball-end, length 210 mm

Bondhus 1/2" ball-end hex key with a 210 mm length is a tool for driving inch-sized hex (Allen) fasteners. The ball-end geometry permits insertion at an angle, enabling access to fasteners in confined or awkward positions while the long shank increases reach. Constructed by Bondhus to provide a tight fit and reliable torque transfer, this hex key is intended for use where inch hex fasteners are specified.

Advantages

The ball-end design permits angled engagement up to several degrees from perpendicular, reducing the need for disassembly to reach offset fasteners. A 210 mm length provides extended reach for recessed or hard-to-reach fasteners. The solid, single-piece construction delivers consistent torque transmission and minimizes tip deformation. The tool’s inch size and precise machining ensure compatibility with inch hex fasteners and reduce rounding of fastener heads.

Suitable for

• Maintenance and repair of equipment using inch hex fasteners
• Assembly tasks on machinery and furniture with inch-threaded hex bolts
• Automotive and mechanical work that requires access in confined spaces
• Service operations where angled entry to the screw is necessary

Key specifications

• Drive type: inch hex (Allen) key
• Size: 1/2 inch
• Tip style: ball-end for angled engagement
• Overall length: 210 mm
• Construction: single-piece hardened tool steel for durability

How to use

Select the 1/2" hex key and align the ball-end with the hex recess of the fastener. If direct access is available, insert the straight end for maximum torque; when the fastener is offset or obstructed, use the ball-end at an angle to engage the hex profile. Apply steady turning force perpendicular to the shank where possible. Avoid excessive lateral force on the ball tip to reduce wear. After use, wipe clean and store in a tool holder to protect the tip geometry.

Usage recommendations

For best results, use the straight end for high-torque loosening and the ball-end for installation or access in restricted positions. Inspect the hex tip before use to ensure a precise fit with the fastener; replace the key if the tip shows deformation or rounding. Keep the tool dry and lightly oiled to prevent corrosion.
