Manufactured from Grade 4000 alloy steel with a bright finish, this pin measures 0.5 inches in diameter and 2 inches in overall length. The threaded end allows for extraction using a standard puller, making controlled removal straightforward without damaging mating components. Surface hardness is Rockwell C60-64, with a core hardness of Rockwell C50-58, providing a tough outer layer over a resilient core. This fastener is suited for machinists, tool and die technicians, and maintenance mechanics who need a reliable locating pin that can be removed cleanly under service conditions.\u003c\/p\u003e\n\u003cp\u003eThis dowel pin fits industrial manufacturing, tooling, and MRO (maintenance, repair, and operations) environments where alignment precision is critical. The spiral vent groove allows air and lubricant to escape during press insertion, reducing hydraulic lock and preventing component damage. The threaded pull out end is particularly useful in blind-hole applications where a standard drive-out method is not possible. Typical installations include jig and fixture assemblies, machine tool components, and die sets across light and heavy manufacturing operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral vent groove reduces hydraulic lock during press-fit insertion\u003c\/li\u003e\n  \u003cli\u003eThreaded end enables clean extraction from blind holes without damaging bore\u003c\/li\u003e\n  \u003cli\u003eGrade 4000 alloy steel construction for high strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSurface hardness of Rockwell C60-64 with core hardness of Rockwell C50-58\u003c\/li\u003e\n  \u003cli\u003eBright finish for corrosion resistance in standard shop environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.8.2 and MIL-S-7742 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit dowel pin for precision alignment applications in industrial jigs, fixtures, die sets, and machine tool assemblies requiring a 0.5-inch diameter, 2-inch length spiral vent pull out configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and removal of dowel pins is typically performed by machinists or maintenance mechanics using a hydraulic or arbor press and appropriate extraction tooling. Always verify bore diameter and tolerance before pressing in the pin to ensure proper fit class. For pull out extraction, use a threaded puller matched to the pin end thread specification. Ensure the assembly is fully de-energized and secured before performing any pin installation or removal work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Spiral Vent Pull Out\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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: 4000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Hardness\u003c\/strong\u003e: Rockwell C60-64\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Hardness\u003c\/strong\u003e: Rockwell C50-58\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.8.2, MIL-S-7742\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 04066\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51731186417970,"sku":"04066","price":76.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/485f4138a7214b0cb704d3551942be8f.jpg?v=1788728063","url":"https:\/\/voomisupply.com\/products\/holo-krome-04066-spiral-vent-pull-out-dowel-pin-1-2-x-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
