Key specifications

• Drive profile: Torx T3
• Bit length: 28 mm
• Drive type: Micro bit

How to use

Insert the micro bit securely into a compatible 4 mm micro bit holder or precision screwdriver handle. Align the Torx T3 tip precisely with the screw head, ensuring full engagement before applying gentle, controlled rotational force. Avoid applying excessive axial pressure or lateral force to prevent damaging the delicate fastener or the bit tip.

What to consider before purchase

• Verify that your existing toolholder or handle is compatible with 4 mm micro bits
• Confirm that the required fastener size in your device matches the Torx T3 profile
• Assess whether the 28 mm length provides sufficient reach for your specific application

Usage recommendations: Store the micro bit in a dry, clean environment to prevent corrosion and maintain its precise tolerances. Regularly inspect the tip for signs of wear or damage to ensure optimal performance during precision work.
