Hex key (Allen wrench) Bondhus 8.0 mm — length 162 mm, ball end

Bondhus 8.0 mm hex key with a length of 162 mm and a ball end is a hand tool designed for engaging 8 mm internal hex fasteners where angled access is required. The solid steel construction delivers the rigidity needed to apply torque for tightening and loosening hex bolts and screws, while the extended 162 mm length provides additional reach for recessed or hard-to-access fasteners. The ball end allows the user to work at an angle, improving access in confined spaces without changing the hex interface.

Advantages

The tool combines a straight working leg with a ball end that permits up to approximately 25–30° of angular engagement, making it practical for assemblies with obstructed approach paths. Solid steel construction ensures durability and consistent torque transfer. The 162 mm length increases leverage and reach compared with shorter keys, reducing the need to disassemble surrounding components to access fasteners.

Suitable for (tasks / use cases)

• Mechanical assembly and disassembly of machinery and equipment
• Maintenance and repair tasks in workshops and industrial settings
• Bicycle, automotive and appliance service where angled access to hex fasteners is needed
• Accessing recessed hex bolts in furniture and metalwork

Key specifications

• Hex size: 8.0 mm
• Overall working length: 162 mm
• End type: ball end on one side for angled engagement
• Material: solid steel construction for torque transmission
• Typical angular access with ball end: approximately 25–30°

How to use

Insert the straight or ball end of the hex key into the internal hex socket of the fastener. For direct, high-torque turning use the straight insertion; for clearance or angled approach insert the ball end and engage at the appropriate angle. Apply steady, controlled force to avoid rounding the fastener head. Use the longer 162 mm leg to reach recessed fasteners or to gain additional leverage when loosening tight fasteners.

Usage recommendations

Inspect the fastener and tool before use to ensure proper fit and to avoid damaging the hex profile. For maximum torque and to prevent rounding, use the straight insertion when possible and avoid excessive side loading on the ball end. Store the key in a dry place to limit corrosion and maintain tool condition.
