Hex Key (Allen Key) Bondhus 17.0 mm — length 280 mm, ball end

Bondhus 17.0 mm hex key with a 280 mm length and a ball end is a solid Allen key designed to drive 17.0 mm hex fasteners where extended reach and angled access are required. The long shaft provides access to recessed or hard-to-reach fasteners, while the ball end permits insertion and tightening at slight angles, reducing the need to align the tool perfectly with the fastener head. Constructed for workshop, maintenance and assembly use, this hex key combines length and a tapered ball end profile to improve accessibility in confined spaces.

Advantages

The 280 mm length enables work on deep-set or recessed fasteners without disassembly of surrounding components, and the ball end offers up to approximately 25–30° of angled engagement for easier positioning in tight areas. Its solid construction ensures reliable torque transmission to 17.0 mm hex fasteners and resists bending under normal workshop loads. The tool’s design reduces the need to reposition hands or the workpiece when accessing obstructed fasteners.

Suitable for

• Automotive and motorcycle maintenance where long-reach access to hex fasteners is needed
• Industrial assembly and machinery service with recessed or obstructed fastener locations
• Workshop repairs, equipment maintenance, and furniture assembly requiring angled access

Key specifications

• Size: 17.0 mm hex drive
• Overall length: 280 mm
• End style: ball end (enables angled engagement)
• Material/Construction: solid hex key designed for torque transmission (manufacturer-grade steel)
• Application: manual hand tool for tightening and loosening hex fasteners

How to use

Insert the 17.0 mm end fully into the hex fastener to ensure maximum contact between the flats. For straight access use the long shaft in-line with the fastener; for obstructed or angled access engage the ball end, allowing the tool to seat at a slight angle. Apply steady, controlled torque and avoid sudden impacts. When more torque is required, use a longer lever or a different tool rated for higher torque rather than exerting excessive force that could deform the key or fastener.

Usage recommendations

Inspect the hex key and fastener for wear before use. Keep the tool clean and free of oil to maintain grip, and store in a dry place. Do not use the ball end for high-torque operations where full-face engagement is required; instead, use the straight end to reduce risk of rounding the fastener.
