Durable and accurate measurement tool - Strong material and wear resistance: Built with an ultra hard Tungsten carbide anvil and a stainless steel body, providing long life and reliable performance in everyday use. The stainless steel construction offers high strength and good mechanical properties. - Precise and easy to operate: High spindle accuracy allows reliable readings when the workpiece is placed between the spindle and the anvil. Adjust the main shaft to obtain accurate data, and use the ratchet pin handle to apply consistent force without over-tightening. - Versatile measurement capability: This alloy micrometer set can function as an outer diameter micrometer and as a thickness measuring ruler, enabling accurate measurements of length, diameter, or thickness in a single tool. - Practical and trustworthy: Designed for professional use in mechanical and industrial settings, delivering repeatable results with durable materials and straightforward operation. Use scenarios - Quality control in machining: Verify outer diameters of shafts, pins, and cylindrical components to ensure they meet specifications during production or final inspection. - Sheet and plate thickness checks: Measure the thickness of metal sheets, shims, or small components to confirm tolerances in fabrication or assembly processes. - Assembly and maintenance: Check critical clearances and part tolerances during equipment assembly or repair to ensure proper fit and function.
