A Micro screw is a small screw used to measure the size of an object. It has various attachments and can measure different objects. Some are used to measure depths while others measure the diameters and thickness of tubes. These screw instruments can be used in the metric and US systems of measurement.

In addition to offering improved strength and precision, the Micro Screw System offers several unique features. These include enhanced stability at reduced feed rates, a fully CD pattern screw head, and optimised lagging geometry. They are also available in a wide range of sizes, ranging from 6mm to 22mm in 1mm increments.

Micro screws are commonly found in electronic devices. The proper micro screwdriver is crucial for successfully fastening these tiny components. These screws are also widely used in miniature model vehicles. As such, it is best to choose an insulated screwdriver to reduce the risk of electrical shock, which can damage delicate electronic components.
