Pin gages are precision inspection tools used to verify hole diameters, slot widths, and bore tolerances in machined or fabricated workpieces. The minus designation means the gage is ground to the lower boundary of the tolerance range, making it the go\/no-go member used to confirm a hole is not undersized. Constructed from steel, this gage is a standard item in any quality control or machine shop environment where tight dimensional verification is required.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are general-purpose inspection tools suited for production floor checks and incoming quality control in machine shops, fabrication facilities, and manufacturing environments. The 0.174-inch size is commonly used when checking drilled, reamed, or punched holes in metal, plastic, or composite parts. This gage is appropriate for use by machinists, quality technicians, and tool-and-die professionals performing dimensional inspection to drawing specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ accuracy with a minus tolerance of 0.0002 inches for lower-boundary hole verification\u003c\/li\u003e\n  \u003cli\u003e0.174-inch nominal diameter covers a common small-bore inspection range\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and wear resistance in production environments\u003c\/li\u003e\n  \u003cli\u003eMinus plug designation confirms holes are not undersized during go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ minus plug pin gage for dimensional inspection of 0.174-inch nominal diameter holes in machined, drilled, or reamed workpieces across standard manufacturing and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages require no installation but should be handled with care to avoid nicks, burrs, or surface contamination that could affect measurement accuracy. Clean the gage and the hole being inspected before use. Store the gage in its protective sleeve or case when not in use to prevent corrosion and surface damage. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.174 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: Class ZZ Minus\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\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: 19-174-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51723133288754,"sku":"19-174-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e87e4a2a84614720c5f7b2f83744db78.jpg?v=1788601059","url":"https:\/\/voomisupply.com\/products\/spi-19-174-2-class-zz-minus-plug-pin-gage-0-174-in","provider":"Voomi Supply","version":"1.0","type":"link"}
