Hex Key Bondhus 6.0 mm, length 139 mm, ball end

Bondhus 6.0 mm hex key, 139 mm long with a ball end, designed for driving 6.0 mm hex fasteners in confined or angled spaces. The straight leg provides leverage while the ball end permits up to approximately 25–30 degrees of angled entry, facilitating work where direct access is restricted. Constructed for a precise fit to hex bolts and screws, this tool suits maintenance, assembly and repair tasks in workshops, industrial settings and home DIY projects.

Advantages

The ball end configuration allows angled engagement without stripping the fastener head, improving access in tight assemblies. The 139 mm length offers a balance of reach and control for both shallow and recessed fasteners. Manufactured to provide a snug fit on 6.0 mm hex heads, the key reduces cam-out and wear on fasteners. The simple, single-piece design ensures durability and straightforward handling during repetitive use.

Suitable for

• Reaching hex bolts and screws in confined or hard-to-reach locations
• Maintenance and repair of machinery, equipment and bicycles
• Assembly work requiring angled entry to fasteners
• DIY projects where a precise 6.0 mm hex fit is needed

Key specifications

• Hex size: 6.0 mm
• Overall length: 139 mm
• Tip type: ball end for angled entry
• Finish: corrosion-resistant surface treatment (manufacturer standard)
• Construction: one-piece hex key for torque transfer and durability

How to use

Insert the short or long end into the 6.0 mm hex socket of the fastener, depending on the required reach and torque. For tight spaces or angled approaches, use the ball end to engage the fastener at an angle up to the ball end's design limit. Apply steady, controlled torque to avoid rounding the fastener. After use, wipe clean and store in a tool holder or rack to prevent corrosion and maintain the precise fit.

Usage recommendations

Choose the straight leg for higher torque tasks and the ball end when access is restricted. Avoid excessive force at extreme angles to prevent fastener damage. Regularly inspect the hex key tip for wear and replace if rounding is observed to preserve proper engagement with 6.0 mm fasteners.
