Hex key (allen wrench) Bondhus 17.0 mm, length 156 mm

Bondhus hex key 17.0 mm with a 156 mm overall length is a solid Allen wrench designed to drive 17 mm internal-hex fasteners. Made for tasks that require a longer reach, the tool provides a precise fit between the driver and fastener to reduce rounding and enable reliable torque transfer. The straight shank and fixed hex profile make it suitable for workshop, maintenance and assembly work where access and control are important.

Advantages

The hex key is manufactured to maintain a tight tolerance on the hex profile for consistent engagement and reduced fastener wear. Its 156 mm length gives extended reach into recessed or hard-to-access fasteners while preserving hand leverage. The solid construction provides torsional strength for repeated use and helps deliver predictable torque without slipping. Its simple design requires no additional components and is compatible with standard 17 mm internal-hex heads.

Suitable for

• Workshop repairs and general mechanical maintenance
• Assembly of furniture, machinery or equipment with 17 mm hex sockets
• Servicing recessed or hard-to-reach fasteners
• Tasks requiring consistent torque transfer and reduced fastener rounding

Key specifications

• Hex size: 17.0 mm
• Overall length: 156 mm
• Tool type: solid hex (Allen) key
• Drive profile: internal hex suitable for 17 mm fasteners
• Construction: single-piece, torsion-resistant shank

How to use

Insert the 17.0 mm hex end fully into the fastener to ensure maximum contact between the tool and the internal hex. Apply steady torque in the required direction using appropriate hand positioning along the shaft; for higher torque needs, use the longer arm for leverage. Avoid using the tool on damaged or heavily rounded fasteners to prevent further wear. After use, clean any debris from the hex profile and store in a dry location to prevent corrosion.

Usage recommendations

For best results, use the Bondhus 17.0 mm hex key on properly sized and undamaged 17 mm internal-hex fasteners. Inspect the tool and fastener before applying high torque and consider using torque-limiting equipment if precise torque values are required. Keep the tool clean and dry to maintain a precise fit and long service life.
