This pin measures 0.25 inches in diameter with an overall length of 0.75 inches. It is manufactured from C-1215 alloy steel and features a threaded end for pull-out removal without the need for a press or punch. The flat vent groove allows trapped air and fluids to escape during insertion, reducing hydraulic lock in blind-hole applications. Machinists, toolmakers, and maintenance technicians install this type of pin where repeatable, accurate part location is required.\u003c\/p\u003e\n\u003cp\u003eThis dowel pin is suited for use in precision-bored holes in tooling plates, fixtures, dies, and machined components across light and heavy manufacturing settings. The threaded end style makes it practical in applications where the pin must be removed frequently or where drive-out access from the back of the assembly is not available. It conforms to ASME B18.8.2, making it a direct fit in applications that specify that fastener standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat vent groove relieves hydraulic lock in blind-hole installations\u003c\/li\u003e\n  \u003cli\u003eThreaded end allows pull-out removal without rear access\u003c\/li\u003e\n  \u003cli\u003eC-1215 alloy steel construction for strength and machinability\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of -0.0001 to 0.0001 inches ensures precision fit\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.8.2 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-specification dowel pin for precision fixturing and tooling assemblies requiring a 0.25-inch diameter flat vent pull out pin per ASME B18.8.2.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDowel pins of this type are typically installed by toolmakers or machinists using a drill press or hand tools in a controlled shop environment. Ensure the receiving bore is reamed to the correct tolerance before installation to maintain the specified fit. The threaded end requires a compatible pull-out tool or threaded rod for removal. Do not hammer directly on the threaded end, as this can damage the threads and make future removal difficult.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 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\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\u003eEnd Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Flat Vent Pull Out\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: 0.01 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: 31401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51984550592818,"sku":"31401","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5dc3cfd532a6c4269c23157a2e4cf65c.jpg?v=1789984857","url":"https:\/\/voomisupply.com\/products\/jergens-31401-flat-vent-pull-out-dowel-pin-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
