It measures 5\/8 inch in diameter and 2.5 inches in overall length, with a threaded end design that allows controlled extraction from blind holes. The flat vent channel along the pin body allows trapped air and lubricant to escape during press-fit installation, reducing hydraulic lock. This pin is used in precision fixturing, tooling, and mechanical assembly applications by machinists, tool and die makers, and industrial maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eFlat vent pull out dowel pins are specified in applications where a standard solid pin cannot be retrieved without damage to the workpiece or fixture. The threaded end accepts a standard puller or threaded rod, enabling clean removal from tight-tolerance bores. Typical use cases include jig and fixture plates, die sets, and machine component alignment where repeated disassembly is required. The tight diameter tolerance of -0.0001 to +0.0001 inches ensures consistent location accuracy across assembly cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat vent design relieves hydraulic pressure during insertion, preventing galling and easing press-fit installation\u003c\/li\u003e\n  \u003cli\u003eThreaded end enables controlled extraction without damaging the mating bore\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of -0.0001 to +0.0001 inches supports precise locating applications\u003c\/li\u003e\n  \u003cli\u003eC-1215 alloy steel construction provides good machinability and consistent mechanical properties\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.8.2 fastener standard for dimensional conformance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for jigs, fixtures, die sets, and precision tooling assemblies requiring a 5\/8-inch diameter 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 a qualified machinist or maintenance technician. Ensure the mating bore is clean, deburred, and within tolerance before driving the pin. Power down and de-energize any associated equipment before servicing tooling or fixtures. Use a proper pin driver or press for installation and a threaded puller for extraction  -  do not strike the threaded end directly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5\/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: 2.5 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: 0.13 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: 31443\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51972313153842,"sku":"31443","price":17.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd540f84a1734ff2a53933f14b581a44.jpg?v=1789966140","url":"https:\/\/voomisupply.com\/products\/jergens-31443-flat-vent-pull-out-dowel-pin-5-8-x-2-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
