Outside micrometer for measuring external thickness and diameter of small parts. Built for mechanics, technicians, engineers and scientists who need reliable, repeatable measurements. Key benefits Accurate, repeatable readings: uses a calibrated screw mechanism for precise measurement of length, diameter or thickness. Longlasting performance: measuring faces are made of quality cemented carbide and the frame is cast iron, giving wear resistance where it matters and overall sturdiness. Practical and easy to use: designed specifically for external measurements on small parts, reducing setup time and measurement error in workshop and lab settings. Versatile compatibility: suited to a wide range of small components found in machining, assembly and inspection work. Main features Function: outside micrometer for external thickness and diameter measurement. Construction: cemented carbide measuring faces and cast iron body for durability and stable performance. Measurement principle: precision screw (calibrated) provides fine, controllable movement and accurate distance measurement. Target users: mechanics, technicians, engineers, scientists working on small parts and components. Typical use scenarios Workshop quality control: check the outside diameter of turned shafts and pins to verify they meet tolerances before assembly. Component inspection in manufacturing: measure thickness of small stamped parts or spacers during incoming inspection or inprocess checks. Laboratory or research measurement: determine the external dimensions of small samples or prototypes where precise, repeatable readings are required. Practical notes suited for external measurements of small parts; follow standard micrometer handling and calibration practices for maximum accuracy. Robust materials and calibrated screw design help maintain measurement integrity over repeated use.
