Manufactured by Swiss Precision Instruments (SPI) and registered to ISO 9001, the set carries a minus tolerance of 0.0002 inch per NIST-traceable calibration. Each pin is fabricated from hardened drill rod heat treated to RC 60-62 hardness, ground to a 10 microinch finish or better, and individually marked with its nominal size and tolerance direction. The set is supplied with a certificate of accuracy in the included molded plastic carrying case. Serial number 1000869 is visible on the certificate of accuracy shown inside the case. The case exterior is labeled \"M1 Minus 190 Piece,\" with the operator label \"FMI-1114\" and a \"Verify Before Use\" sticker applied. Pin gages of this type are used for hole size verification, slot width inspection, Go\/No-Go gaging, and inter-hole distance measurement in precision machining, toolroom, and quality control environments. The range of 0.061 to 0.250 inch covers a high-demand span for common drilled and reamed hole sizes encountered in production and inspection work. SPI is an established US metrology brand with broad distribution through major MRO channels including MSC Industrial Supply and Penn Tool Co.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0426-01387\u003c\/p\u003e","brand":"SPI","offers":[{"title":"Default Title","offer_id":49589144781040,"sku":"m01387","price":159.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/83819A4F-5B50-4E00-B195-FF944AF0FC0B_20260724154024805.png?v=1784907625"},{"product_id":"spi-pin-gage-set-22-147-3-0061-in-to-0250-in-0001-in-step-increments-01388","title":"SPI 22-147-3 Pin Gauge Set 0.061 to 0.250 in 0.001 in Step Increments","description":"\u003cp\u003eA Class ZZ pin gage set from SPI (Swiss Precision Instruments), part number 22-147-3, covering a measurement range of 0.061 in. to 0.250 in. in 0.001 in. increments for a total of 190 individual pins. Tolerance is minus 0.0002 in. (M1 Minus), and each pin is hardened steel to RC 60–62 with a 10 microinch or better surface finish. Each pin is individually size-etched for easy identification and organizes in a red foam-lined molded plastic carrying case with labeled slots. The set is NIST traceable and registered to ISO 9001, and originally shipped with a Certificate of Accuracy. The case lid label identifies the set as M1 Minus, 190 pieces, size range 0.061 in. to 0.250 in., accuracy +0.0000 in. \/ 0.0002 in. SPI is a well-established brand in US precision metrology. The tray serial number visible on the foam insert is S\/N:086356. Internal facility reference FMI-0627 is noted on the case label. Commonly used for hole size verification, slot width measurement, go\/no-go gaging, and inter-hole distance calculation in machining, toolroom, and quality control environments. Overall pin length is 2 in. Pin count should be verified against the 190-piece tray layout prior to listing.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0426-01388\u003c\/p\u003e","brand":"SPI","offers":[{"title":"Default Title","offer_id":49589151891696,"sku":"m01388","price":159.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/C4F3E467-FB8D-49A0-B94A-C820CCEFDF2D_20260724154032137.png?v=1784907632"},{"product_id":"spi-pin-gage-set-22-147-3-0061-in-to-0250-in-0001-in-step-increments-01389","title":"SPI 22-147-3 Pin Gauge Set 0.061 to 0.250 in 0.001 in Step Increments","description":"\u003cp\u003eThe SPI 22-147-3 is a Class ZZ pin gage set covering a measurement range of 0.061\" to 0.250\" in 0.001\" increments, comprising 190 individual hardened steel pins. Each pin is centerless lapped to a 10 microinch finish or better and heat treated to a hardness of 60 to 62 RC. The set carries a minus tolerance of 0.0002\", meaning each pin is manufactured at nominal size or slightly below, making this set appropriate for verifying the upper limit of hole sizes. Pins are marked with both size and tolerance direction for easy field identification. The set is housed in a molded plastic carrying case with individually labeled positions for each pin size. Internal reference FMI-0984 and serial number 1001582 are visible on the case and tray respectively. SPI pin gage sets are traceable to NIST standards and are manufactured to Class ZZ specifications per ANSI\/ASME B89.1.5. Applications include hole size verification, slot width measurement, distance between holes, and Go\/NoGo inspection tasks across manufacturing, quality control, and toolroom environments. The set spans the M1 range as defined by industry standards. A \"VERIFY BEFORE USE\" label is present on the case and tray, indicating prior use in a calibration-controlled environment.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0426-01389\u003c\/p\u003e","brand":"SPI","offers":[{"title":"Default Title","offer_id":49589155332336,"sku":"m01389","price":159.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/31AF5973-B92A-4F21-A5FF-DB4BDCD3FDA8_20260724154036259.png?v=1784907637"}],"url":"https:\/\/mroexchange.com\/collections\/spi.oembed","provider":"MRO Exchange","version":"1.0","type":"link"}
