This minus-standard inch set includes 250 individual gage pins ranging from 0.251?in to 0.500?in in 0.001?in increments, providing comprehensive coverage for common inspection needs. Each pin is crafted from high-quality tool steel, hardened to 60–62?HRC and precision-ground to a 10-micron finish for smooth fit, dimensional stability, and long-term durability. Classified to Class ZZ accuracy (–0.0002?\/+0.0000?), the set ensures tight-tolerance measurements suitable for inspection departments, quality labs, and machining facilities. Designed for organization and ease of use, the pins are stored in a durable, dust-proof plastic case with clearly marked sizes for fast selection, while each 2-inch-long pin allows convenient handling for manual or fixture-based inspections. Ideal for verifying hole diameters, checking parallelism and fit, calibrating measuring tools, and confirming dimensional accuracy in production runs, this set combines precision, ruggedness, and reliability. Perfect for machine shops, aerospace, automotive, and metrology environments, the HHIP 4101-0012 Pin Gage Set is engineered to maintain flatness, accuracy, and repeatability for years of dependable service and professional performance.\u003cbr\u003e\n.PRECISION-GRADE MEASUREMENT: The HHIP 4101-0012 Class ZZ pin gage set covers 0.251\" to 0.500\" with 250 fully hardened pins for accurate hole verification, distance measurement and calibration in tool rooms and inspection labs where tight tolerance matters\u003cbr\u003e\n.HARDENED AND GROUND FOR DURABILITY: Each gage pin is made from high-carbon tool steel, hardened to 60-62 Rockwell C for long-term wear resistance. Surface finish is 10 microns or better, providing smooth precise fit and extended service life in daily use.\u003cbr\u003e\n.CLASS ZZ ACCURACY MINUS TOLERANCE: Designed to meet Class ZZ specs of –0.0002\" \/+0.0000\", each pin is precision-ground for repeatable readings. Ideal for checking bore diameters, calibrating instruments, and verifying machined part dimensions accurately.\u003cbr\u003e\n.ORGANIZED FOR EFFICIENCY AND PROTECTION: Supplied in a sturdy, dust-proof plastic case with clearly marked sizes for fast identification. The compact layout protects pins from contamination, damage, keeps edges clean for accurate inspection and assembly\u003cbr\u003e\n.PROFESSIONAL INSPECTION STANDARD: Each pin gage is 2\" long, uniformly finished, and manufactured to tight tolerances for dimensional control and quality assurance. Perfect for machinists, calibration techs, and engineers needing repeatable precision.\u003c\/p\u003e","brand":"Zoro Tools, Inc.","offers":[{"title":"Default Title","offer_id":51020885328178,"sku":"W9Y-ZTI-G2498379","price":211.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0711\/4748\/7538\/files\/71dxfXXdXFL.jpg?v=1774695619","url":"https:\/\/kartit.us\/products\/w9y-zti-g2498379","provider":"KARTiT","version":"1.0","type":"link"}
