Hex key (Allen wrench) Bondhus 5.0 mm — length 119 mm, ball end

Bondhus 5.0 mm hex key with a length of 119 mm and a ball end is a medium-length Allen wrench designed for driving 5.0 mm hex fasteners in confined or angled spaces. The ball end provides accessibility to fasteners at off-axis angles, while the straight tip ensures positive engagement for higher torque when alignment is possible. The 119 mm length balances reach and control for assembly, maintenance and repair tasks.

Advantages

The ball end allows for up to approximately 25–30 degrees of angular entry, enabling access to hard-to-reach fasteners without compromising the ability to apply torque. The medium 119 mm length offers reach into recessed fasteners while maintaining good leverage and control. Precision-formed hex profile reduces rounding of fastener corners and improves fit. Durable steel construction and a consistent heat treatment provide wear resistance and a long service life under normal use.

Suitable for

• Mechanical assembly and disassembly where a 5.0 mm hex drive is required
• Bicycle maintenance and adjustment of components using 5.0 mm hex bolts
• Furniture assembly and fittings in confined spaces
• Repair and maintenance tasks in workshops, garages and industrial settings

Key specifications

• Driving tip: 5.0 mm hex
• Overall length: 119 mm
• Tip style: ball end on one end, straight hex on the other (ball end allows angled entry)
• Material: hardened steel with protective finish for corrosion resistance
• Typical angular entry with ball end: enables off-axis engagement (approx. 25–30°)

How to use

Insert the 5.0 mm tip into the hex socket of the fastener. For straightforward, high-torque turning, use the straight end aligned with the fastener axis. When the fastener is obstructed or the approach angle is restricted, use the ball end and engage at an off-axis angle to start turning. Apply steady, controlled force to avoid cam‑out or stripping; reduce leverage if resistance increases. After use, wipe the tool clean and store it in a tool holder or rack to prevent corrosion and damage.

Usage recommendations

Use the straight end for maximum torque and the ball end for angled access. Avoid using excessive impact or prying forces. Keep fastener and tool contact surfaces clean to maintain fit and minimize wear.
