Hex key (Allen wrench) Bondhus 1.50 mm, length 44 mm

Bondhus hex key (Allen wrench) 1.50 mm, length 44 mm is a single-size hand tool designed for driving hex socket screws and fasteners commonly found in electronics, precision mechanics and hobby applications. Its compact 44 mm length and slim profile allow access to tight spaces and recessed fasteners while the steel construction provides the rigidity required for controlled manual torque.

Advantages

The 1.50 mm hex profile ensures a precise fit with small hex socket screws, reducing cam-out and fastener damage. A 44 mm overall length balances reach and control for assembly, repair and adjustment tasks. Constructed from hardened steel, the tool resists bending under normal hand-applied torque and maintains its shape over repeated use. Its small size makes it easy to carry in a tool roll, electronics kit or pocket.

Suitable for

• Driving and removing small hex socket screws in electronic devices
• Precision mechanical assembly and adjustment
• Hobby and model-making tasks requiring fine fastener control
• Maintenance and repair of appliances, instruments and small equipment

Key specifications

• Hex tip size: 1.50 mm
• Overall length: 44 mm
• Material: hardened steel
• Tool type: single-size hex key (Allen wrench)
• Drive style: manual hand tool for hex socket fasteners

How to use

Select the 1.50 mm hex key and align the hex tip with the fastener socket. Insert the tip fully to ensure an even contact surface, then apply steady, controlled hand torque to turn the fastener clockwise to tighten or counterclockwise to loosen. For recessed or hard-to-reach screws use the full 44 mm length to improve access while maintaining a firm grip on the tool. Avoid applying excessive force beyond typical hand torque to prevent tool or fastener damage.

Usage recommendations

Use the hex key for small-diameter hex screws in electronics and precision work; store it in a dedicated slot or protective sleeve to prevent tip wear and maintain accurate fit. If higher torque is required, use an appropriately sized driver or a tool designed for greater leverage to avoid overstressing the hex key.
