Plug gages of this class are go\/no-go inspection tools used to confirm that drilled, reamed, or bored holes fall within a specified dimensional range. The Class ZZ Plus designation indicates a tighter tolerance grade suited for quality-control checks on production parts and tooling. At 0.2 pounds, it is a compact, hand-held instrument used by machinists, quality technicians, and toolmakers during incoming inspection or in-process measurement.\u003c\/p\u003e\n\u003cp\u003eThis gage is appropriate for inspection applications in machine shops, manufacturing cells, and toolrooms where bore diameter conformance must be documented. It is used with cylindrical bores in metal workpieces and is well-suited to bench inspection stations or inline quality checkpoints. The 0.604-inch nominal diameter targets a specific bore size common in precision component work. Installers and inspectors working to tight tolerances will use this gage alongside surface plates, gage blocks, or calibration standards to maintain traceability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.604 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches supporting Class ZZ Plus accuracy requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under shop conditions\u003c\/li\u003e\n  \u003cli\u003eCompact at 0.2 pounds for easy single-hand use at the bench or workstation\u003c\/li\u003e\n  \u003cli\u003eGo\/no-go format provides fast pass-fail inspection without additional calculation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for use with cylindrical bores requiring a 0.604-inch nominal diameter check.

Before use, clean the gage and the bore being inspected to remove chips, coolant, and debris that could affect the reading. Do not force the gage member into the bore, as forcing can damage the gage land or the workpiece surface. Store the gage in a protective case away from other metal tooling to prevent wear and nicking of the precision ground surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.604 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (mm)\u003c\/strong\u003e: 0.0002 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 29-604-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51695630450994,"sku":"29-604-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f32656ea9f2742d45aed1a48f550e30_77475a9d-0759-4ac5-8c8c-fcc18f69098d.jpg?v=1788337039","url":"https:\/\/voomisupply.com\/products\/spi-29-604-6-class-zz-plus-plug-gage-0-604-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
