Product Description The external micrometer is highly accurate to a strictly minimal variance. For your confidence, it has undergone rigorous testing to guarantee consistent precision and quality. The external micrometer is ideal for mechanical or engineering environments where precise dimension measurement is crucial. With anvils made of tungsten carbide, the micrometer is resistant to corrosion. The positive spindle lock holds the anvils in place to ensure an accurate recording of measurement. It has an adjustment spanner for easily resetting back to zero and comes in a tailor-made case for storage and easy carrying. Micrometers such as these are commonly used for maintenance work or engineering applications. It can measure the outer dimensions of an object such as a metal pipe or an electrical component. Key Features - Ideal for making root tangent measurements on spur gears and helical gears - Can measure gear teeth and paper thickness - 60.0mm diameter carbide disc face - Non-rot
