Hex key (allen wrench) Bondhus 5/8 in, length 248 mm, ball end

Bondhus hex key 5/8 in with a 248 mm long shaft and a ball end is designed to drive hex fasteners where extended reach and slight angular entry are needed. The long arm provides increased leverage and access into recessed or hard-to-reach fasteners while the ball end allows engagement at an angle, reducing the need for perfect alignment. This tool is suitable for workshop maintenance, assembly and repair tasks where reach and flexibility are required.

Advantages

The long 248 mm length delivers extra reach and mechanical advantage compared with standard short wrenches. The ball end permits insertion at moderate angles, allowing continued torque transfer when direct axial access is blocked. Constructed to provide a secure hex fit, the tool helps reduce fastener rounding and slipping. A straight, solid shaft maintains stiffness for reliable torque application while enabling access into narrow cavities.

Suitable for

• Reaching recessed hex fasteners in machinery and equipment
• Maintenance and repair work in workshops and industrial settings
• Assembly tasks where space constraints require angled entry
• Automotive and mechanical service where extended leverage is beneficial

Key specifications

• Size: 5/8 inch hex
• Overall usable length: 248 mm
• End style: ball end on working tip for angled access
• Shaft type: long straight arm for extended reach and leverage
• Intended use: driving hex (Allen) fasteners

How to use

Insert the 5/8 in hex tip into the corresponding fastener recess, ensuring the hex faces sit fully on the fastener. For direct access, engage the tip axially and apply steady torque. When straight access is obstructed, use the ball end feature to engage the fastener at a slight angle; maintain firm control of the shaft to avoid slipping. Use the long arm for increased leverage when loosening tight fasteners, and switch hands or reposition the tool as needed to work within confined spaces. Avoid using excessive impact or prying forces that could damage the tool or fastener.

Usage recommendations

For best results, match the 5/8 in hex key precisely to the fastener size and keep contact surfaces clean. Apply steady, controlled torque rather than sudden force; if a fastener is heavily corroded, apply penetrating lubricant first. Store the hex key in a rack or pouch to protect the working tip and maintain accurate fit.
