Hex Key (Allen Wrench) Bondhus 19.0 mm — length 295 mm

Bondhus Hex Key (Allen Wrench) 19.0 mm — length 295 mm is a solid single-piece hand tool designed for driving hex-socket fasteners with a 19.0 mm recess. The 295 mm overall length provides extended reach and additional leverage compared with shorter keys, making it suitable for tasks where fasteners are recessed or access is limited. The tool is intended for workshop, maintenance and assembly environments and is compatible with 6-sided socket bolts and screws requiring manual torque.

Advantages

The one-piece construction provides torsional strength and reduces the risk of bending or breakage under normal manual use. Its long length gives improved reach into deep or hard-to-access locations while offering better torque control. The precisely machined hex profile ensures a secure fit with hex-socket fasteners, reducing cam-out and wear on both tool and fastener. The straightforward design is low-maintenance and suitable for repeated professional and DIY use.

Suitable for

• Reaching recessed hex-socket bolts and screws in machinery or equipment
• Maintenance and repair tasks in workshops and service departments
• Assembly work where extended reach or additional leverage is required
• Manual tightening and loosening of 6-sided socket fasteners

Key specifications

• Head size: 19.0 mm hex
• Overall length: 295 mm
• Construction: solid single-piece hex key
• Compatibility: 6-sided (hex) socket fasteners
• Intended use: manual torque application, reach for recessed fasteners

How to use

Insert the 19.0 mm hex head into the corresponding hex recess of the bolt or screw, ensuring full engagement of the hex profile. Apply steady manual force to the long arm to tighten or loosen the fastener; the extended length increases leverage so apply controlled torque to avoid over-tightening. Where space allows, use the long arm for high-torque turns and orient the tool for best access. After use, wipe clean to remove debris and store in a tool rack or toolbox to protect the hex profile.

Usage recommendations

Use the key only with matching 19.0 mm hex fasteners and keep hands clear of pinch points when applying force. Avoid using the tool as a pry bar, hammer, or with added cheater bars beyond normal manual torque to prevent damage or personal injury. Regularly inspect the hex profile for wear and replace the tool if the fit becomes loose or rounded.
