A ratchet stop provides consistent, repeatable measuring pressure by limiting the force applied to the thimble during measurement, reducing the risk of over-tightening and improving reading accuracy. This component is a direct replacement or spare part intended for machinists, quality control technicians, and precision measurement professionals who rely on Starrett 436 series micrometers in shop or inspection environments. The part ships individually and is sold as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis ratchet stop is suited for bench-top inspection stations, machine shop floors, and tool crib applications where maintaining measurement consistency across multiple operators is critical. It fits directly into the Starrett 436 micrometer assembly, restoring proper torque-limiting function when the original ratchet stop is worn or damaged. No calibration is included and no traceability certification is provided with this part.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned specifically for Starrett 436 series micrometers\u003c\/li\u003e\n  \u003cli\u003eRatchet stop mechanism provides repeatable measuring pressure\u003c\/li\u003e\n  \u003cli\u003eReduces operator-induced measurement error from over-tightening\u003c\/li\u003e\n  \u003cli\u003eSold as a single replacement unit\u003c\/li\u003e\n  \u003cli\u003eNo calibration or traceability certification included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the Starrett 436 micrometer series as a direct accessory replacement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or metrologist familiar with micrometer disassembly and reassembly. Ensure the micrometer is removed from service before replacing the ratchet stop. Follow the micrometer manufacturer's service documentation for proper component seating and reassembly sequence. After installation, verify measurement repeatability with a known standard before returning the tool to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Starrett 436\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72279\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542475833650,"sku":"72279","price":30.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fad794f02d0426995a6a8b3086e9be8.jpg?v=1785901301","url":"https:\/\/voomisupply.com\/products\/starrett-72279-micrometer-ratchet-stop-for-starrett-436","provider":"Voomi Supply","version":"1.0","type":"link"}
