Advantages
This micro flat screwdriver bit delivers exceptional precision and a secure fit, which significantly reduces the risk of cam-out and damage to delicate screw heads.

Suitable for
Precision electronics repair and maintenance
Delicate mechanical assembly tasks
Working with miniature flat-head screws
Professional maintenance and laboratory equipment servicing
When it may not be suitable
This product is not designed for heavy-duty construction, high-torque industrial fastening, or driving large fasteners where standard-sized screwdriver bits are required. It is also incompatible with power tools or standard 1/4-inch bit drivers without an appropriate 4 mm adapter.
Key specifications
Bit type: Micro flat
Length: 28 mm
Drive form: 4 mm hex
Tip size: 3.5
How to use
Insert the 4 mm hex drive end of the screwdriver bit securely into a compatible precision bit holder or micro screwdriver handle. Align the 3.5 flat tip carefully with the slot of the target screw to ensure full engagement. Apply steady, controlled downward pressure while turning the handle gently to fasten or loosen the screw without stripping the head or damaging the surrounding components.
What to consider before purchase
Verify that your existing screwdriver handle or bit holder is compatible with a 4 mm hex drive form.
Confirm that the 3.5 flat tip size matches the specific dimensions of the fasteners you intend to use.
Assess whether your application requires precision micro tools rather than standard-sized fastening equipment.
Usage recommendations: Always select the correct tip size and drive form to match your fasteners, and store the micro bit in a dry, organized case to prevent loss or mechanical wear.
