Starrett ST436.1AXRLZ Outside Micrometer Set 0-3" .0001" Ratchet Stop Carbide Faces

The Starrett ST436.1AXRLZ is a professional-grade outside micrometer set covering a full 0–3" measuring range with .0001" graduations for exceptional precision. This 3-piece set includes individual 1", 2", and 3" micrometers along with two calibration standards, an adjusting wrench, and a protective carrying case — everything needed for accurate shop-floor measurement right out of the box.

Built on Starrett's legendary Series 436 platform, these micrometers feature carbide-tipped anvils and spindles for long-term wear resistance, a ratchet stop thimble for consistent, repeatable contact pressure, and a lock nut to secure measurements during reading or transfer. The anvils are sized at .250" (6.35mm) diameter, making them easy to position on larger workpieces. A gracefully tapered frame design allows access in narrow slots and tight spaces, while the balanced frame-and-thimble configuration promotes comfortable one-handed operation.

The no-glare satin chrome finish on the thimble and sleeve reduces eye strain under bright shop lighting and provides corrosion resistance for lasting durability. All micrometers and standards store securely in the included protective case for easy organization and portability.
