The Bahco BKE850901N long arm hex key is a hand tool designed for turning hexagonal fasteners where extended reach and increased leverage are required. With a long arm length of 17 cm and a weight of 340 g, this tool offers improved torque control and access to recessed or hard-to-reach bolts. The design focuses on functional durability and straightforward use in mechanical, maintenance, and assembly tasks.

Advantages

The long arm configuration provides greater leverage compared with standard hex keys, while the 17 cm reach enables access to fasteners in deeper or confined spaces. Solid construction delivers dependable performance under repeated use, and the balanced weight supports comfortable handling during tightening and loosening operations.

Suitable for

• Automotive maintenance and repair
• Mechanical assembly and disassembly
• Bicycle and equipment servicing
• Furniture assembly where extra reach is needed
• Workshop and general maintenance tasks

Key specifications

• Tool type: long arm hex key
• Arm length: 17 cm (long arm)
• Weight: 340 g
• Material: hardened steel construction for durability
• Finish: protective coating to resist wear

How to use

Insert the short or long end of the hex key into the hexagonal socket of the fastener, choosing the orientation that provides the best access and torque. Use the long arm to increase leverage when loosening or tightening stubborn fasteners, and use the short arm for higher torque in tighter spaces. Apply steady pressure and avoid sudden force to prevent rounding the fastener head.

Usage recommendations

Regularly inspect the hex key for signs of wear or deformation before use. Select the correct hex key size for the fastener to ensure secure engagement. Store the tool in a dry place to minimise corrosion and maintain performance.
