This fixed reference geometry provides a known baseline for verifying micrometer readings on threaded parts and for routine calibration of micrometers against a 60° thread angle. The 14-234-9 designation identifies the model in SPI's catalog, and the 2-inch range aligns with common measurement tasks in mechanical metrology and quality control. Used in inspection, calibration, and shop-floor metrology, it supports repeatable checks of screw-thread measurements by offering a defined, reproducible reference against which instrument accuracy can be gauged. It is purpose-built for reference standards in assembling and maintaining thread measurement procedures where a precise 60° thread form matters. Having a dedicated standard for 60° threads helps minimize deviations caused by wear or misalignment in hand tools, so technicians can trust their thread measurements when parts require tight tolerances. By anchoring measurement checks to a specific model and range, shops can document calibration history and ensure consistent measurement practice across different operators.\u003c\/p\u003e\u003c\/div\u003e","brand":"SPI","offers":[{"title":"New","offer_id":46259671662826,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-014.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/spi-14-234-9-screw-thread-micrometer-standard-60-degree","provider":"GTG Hardware","version":"1.0","type":"link"}
