Hex Key (Imperial) Bondhus 5/8 in, length 159 mm

Bondhus hex key (imperial) 5/8 in, length 159 mm is a solid L-shaped hex wrench designed to drive hexagonal socket fasteners in imperial sizes. The tool is made for manual tightening and loosening, offering a fixed-length arm for reach and torque. Its 159 mm length provides additional leverage compared to shorter keys while remaining compact enough for workshop and garage use.

Advantages

The hex key features a one-piece L-shaped construction that delivers consistent torque transfer and reduced play at the tip. The imperial 5/8 in size fits corresponding hex socket fasteners precisely. The longer arm length improves leverage for stubborn fasteners, while the short arm can be used where clearance is limited. The simple, robust design makes it suitable for repeated use in maintenance, assembly and repair environments.

Suitable for

• Manual tightening and loosening of 5/8 in hex socket fasteners
• Workshop and garage maintenance tasks
• Industrial assembly and repair where imperial tools are required
• Situations requiring increased leverage or reach compared with shorter hex keys

Key specifications

• Size: 5/8 inch (imperial)
• Shape: L-shaped (short and long arm)
• Overall length: 159 mm
• Drive type: hex (hexagonal socket)
• Use: manual hand tool for driving hex socket fasteners

How to use

Insert the short or long arm of the Bondhus 5/8 in hex key into the hexagonal socket of the fastener. Use the long arm as a handle for greater torque or the short arm for access in confined spaces. Turn clockwise to tighten and counterclockwise to loosen. Apply steady, even force to avoid stripping the fastener head and ensure the key is fully seated before applying high torque.

Usage recommendations

For best results, inspect the hex socket and key tip for wear before use. Select the long arm for higher torque needs and the short arm for tight clearances. Avoid using cheater bars or excessive impact on the tool to prevent deformation. Store the hex key in a dry tool tray or holder to maintain condition and accuracy.
