It measures 3\/8 inch in diameter and 3 inches in overall length, with a threaded end that allows for controlled extraction during tooling and fixture disassembly. The flat vent channel along the body relieves hydraulic pressure during press-fit installation, preventing galling and hydraulic lock in blind-hole applications. This pin is used in precision fixturing, jigs, and machine tooling where repeatable alignment and clean removal are required. Machinists, tool and die makers, and maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis dowel pin fits precision-bored holes in machine fixtures, production jigs, and alignment tooling in both shop and industrial manufacturing environments. The threaded pull-out end is especially suited for blind-hole installations where a standard press-fit pin cannot be driven out from the opposite side. The ASME B18.8.2 standard ensures dimensional consistency for interchangeability across fixtures built to that specification. Typical applications include metal fabrication shops, automated assembly fixtures, and precision machining operations where tight positional tolerances must be maintained across repeated setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat vent design relieves hydraulic pressure during press-fit installation in blind holes\u003c\/li\u003e\n  \u003cli\u003eThreaded end allows extraction with a standard pull-out tool without damaging the bore\u003c\/li\u003e\n  \u003cli\u003eGrade C-1215 alloy steel construction for consistent hardness and machinability\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to -0.0001 to +0.0001 inches for precision alignment fitment\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.8.2 for dimensional interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use component for precision fixturing and jig tooling applications requiring ASME B18.8.2 compliant flat vent pull out dowel pins in 3\/8 inch diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or tool and die technicians using an arbor press or hydraulic press sized for the bore diameter. The receiving hole should be finish-reamed to the appropriate tolerance before installation. Always confirm the threaded pull-out end is accessible before pressing the pin into a blind hole. De-energize and lock out any powered equipment before servicing fixtures that contain these pins.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Flat Vent Pull Out\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0001 to +0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C-1215\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.8.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: JERGENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31424\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52091504820530,"sku":"31424","price":18.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e027e4549e7c968f0d6d88e16960eea.jpg?v=1790063152","url":"https:\/\/voomisupply.com\/products\/jergens-31424-flat-vent-pull-out-dowel-pin-3-8-x-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
