Product Description

These micrometers are highly useful tools for internal linear measurements such as measuring cylinders, rings, setting calipers, comparing gauges and measuring parallel surfaces. The extension rods are made of steel tubing, light in weight, yet extremely rigid. Rods are approximately 9.5mm diameter to meet the requirements of mechanics who prefer this larger diameter. By removing the hardened and ground anvil ends (end caps) of the micrometer head, the rods may be attached to either or both ends of the micrometer as preferred. Each rod may be individually adjusted for wear by the hardened and ground anvil at the end. Tubular measuring rods are lightweight, yet extremely rigid. Rods are insulated, with the exception of 13mm and 25mm sizes also each rod is marked with length. Movement of screw: 13mm.
