Hex Key Bondhus 1.5 mm — 77 mm length, ball end

Bondhus 1.5 mm hex key with a 77 mm length and a ball end is a compact hand tool designed to drive 1.5 mm hex fasteners in confined or hard-to-reach areas. The extended length provides extra reach while the ball end enables engagement of fasteners at an angle, improving access where a straight insertion is not possible. Constructed to suit precision assembly, electronics, instruments and small mechanical tasks, this hex key offers a slim profile for narrow spaces while maintaining control and alignment.

Advantages

The 77 mm shaft gives additional reach without sacrificing maneuverability in tight working environments. The ball end design permits angled entry up to several degrees, making it easier to access fasteners located behind obstructions or in recessed positions. Its 1.5 mm size is appropriate for small hex (imbus) screws commonly found in electronics and precision equipment. The tool’s slim geometry supports accurate torque application and stable engagement with small fastener heads.

Suitable for

• Precision assembly and adjustment of small devices
• Electronics repair and component installation
• Instrument and optical equipment maintenance
• Small mechanical repairs and hobby projects

Key specifications

• Hex key size: 1.5 mm
• Overall length: 77 mm
• Tip type: ball end for angled access
• Tool profile: slim, long-shaft design for confined spaces
• Typical applications: small hex fasteners in precision and electronic equipment

How to use

Insert the 1.5 mm hex tip into the corresponding hex socket of the fastener and apply steady rotational force. For directly aligned fasteners use the tip straight-on to ensure full contact and minimize rounding. When direct access is blocked, engage the ball end at a slight angle to the fastener head; the ball geometry maintains engagement while allowing angular clearance. Use controlled torque appropriate for small screws to avoid damage to fastener heads or components.

Usage recommendations

Use the hex key in clean, well-lit conditions and select the correct 1.5 mm size to prevent stripping. For delicate assemblies, apply minimal necessary torque and support surrounding parts to avoid stress. Inspect the tool tip regularly for wear and replace if the ball end shows deformation to maintain secure engagement.
