Manufactured from C-1215 alloy steel, this pin measures 3\/4 inch in diameter and 2 inches in overall length, with a threaded end that allows controlled extraction without damage to the bore. The flat vent channel runs the length of the pin to relieve air pressure and hydraulic lock during installation, making seating and removal consistent and repeatable. Machinists, tool and die makers, and maintenance technicians working with jigs, fixtures, and production tooling rely on this pin type for applications where frequent disassembly is required.\u003c\/p\u003e\n\u003cp\u003eThis dowel pin is suited for use in machine shop environments, production fixtures, jigs, dies, and other close-tolerance tooling applications. The threaded pull-out design eliminates the need for a press or drift punch during removal, reducing downtime and the risk of bore damage in repeated service cycles. It conforms to ASME B18.8.2, the governing standard for hardened ground machine and dowel pins in North American industrial use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat vent design relieves air and hydraulic pressure during pin insertion for smooth, controlled seating\u003c\/li\u003e\n  \u003cli\u003eThreaded end allows pull-out extraction without pressing or drifting, protecting precision bores\u003c\/li\u003e\n  \u003cli\u003eC-1215 alloy steel construction provides the hardness and machinability required for close-tolerance alignment work\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to -0.0001 to +0.0001 inches for consistent fit in precision-reamed holes\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.8.2 for standardized dimensional compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard component for precision jigs, fixtures, dies, and machined tooling assemblies requiring a 3\/4-inch diameter flat vent pull out dowel pin per ASME B18.8.2.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and removal should be performed by qualified machinists or maintenance technicians familiar with close-tolerance pin work. Ensure the receiving bore is clean, properly reamed to the mating diameter, and free of burrs before seating the pin. Use the threaded end with an appropriate extraction tool for removal  -  do not drive the pin out from the threaded end with a hammer. Consult applicable facility safety and tooling procedures before servicing fixtures under load.\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\/4 inches\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: 2 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: 0.15 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: 31447\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52108641042738,"sku":"31447","price":18.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9e43d27e47dd0ee3e38e5cb5f4ea703.jpg?v=1790075035","url":"https:\/\/voomisupply.com\/products\/jergens-31447-flat-vent-pull-out-dowel-pin-3-4-x-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
