Hex Key (Allen Wrench) Bondhus 5.0 mm — length 119 mm

Bondhus 5.0 mm hex key (Allen wrench) with a length of 119 mm is a hand tool designed to drive 5.0 mm hex fasteners in assembly, maintenance and repair tasks. Constructed from solid steel, the tool transmits torque reliably for tightening and loosening bolts and screws used in machinery, furniture and electronics where a 5.0 mm key is required. The 119 mm length provides reach and leverage for recessed or partially obstructed fasteners while remaining compact enough for toolkits and workbenches.

Advantages

The hex key offers precise fit to 5.0 mm hex sockets to reduce rounding of fastener corners and improve torque transfer. Its solid steel construction ensures durability under repeated use and resists bending when applying moderate torque. The 119 mm shaft length balances accessibility and control: it reaches deeper fasteners and provides additional leverage compared with shorter keys. The simple, one-piece design makes it easy to inspect, store and handle.

Suitable for

• Assembly and disassembly of machinery and equipment with 5.0 mm hex fasteners
• Furniture assembly and adjustment
• Maintenance and repair of bicycles, appliances and small engines
• Electronics and workshop applications requiring precise hex engagement

Key specifications

• Tool type: straight hex key (Allen wrench)
• Hex size: 5.0 mm
• Overall length: 119 mm
• Material: solid steel construction for torque transmission
• Design: one-piece, straight shaft for reach and leverage

How to use

Insert the 5.0 mm hex key fully into the hex socket of the fastener to ensure full contact between the tool and the fastener head. Turn the key clockwise to tighten and counterclockwise to loosen, applying steady pressure to avoid cam-out or rounding. For increased torque, use the long end for leverage and the short end for working in confined spaces; reverse ends as required by the task. After use, wipe the key clean and store it in a designated slot or holder to prevent corrosion and maintain accurate fit.

Usage recommendations

Use the Bondhus 5.0 mm hex key for fasteners matched to the 5.0 mm profile only; avoid forcing the tool on worn or incorrect fastener sizes. When higher torque is needed, consider using proper torque-limiting tools or a larger wrench adapted for hex bits to prevent tool or fastener damage. Keep the key clean and dry to prolong service life.
