It measures 0.5 inches in diameter and 1.5 inches in overall length. The threaded end allows for controlled extraction using a standard pull-out tool, making removal straightforward in maintenance and assembly operations. Surface hardness is rated Rockwell C60-64, with a core hardness of Rockwell C50-58, providing the toughness needed to resist deformation under press-fit and load conditions. Machinists, tool and die technicians, and maintenance mechanics are the primary installers of this type of fastener.\u003c\/p\u003e\u003cp\u003eThis dowel pin is suited for precision alignment applications in machinery, fixtures, jigs, and tooling assemblies across industrial and manufacturing environments. The spiral vent groove relieves hydraulic pressure during insertion into blind holes, preventing hydraulic lock and enabling full seating without damage to the bore or the pin. The threaded end simplifies removal from blind-hole installations where standard drift-pin extraction is not possible.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral vent groove relieves hydraulic pressure in blind-hole applications\u003c\/li\u003e\n\u003cli\u003eThreaded end enables clean pull-out extraction without bore damage\u003c\/li\u003e\n\u003cli\u003eSurface hardness Rockwell C60-64 for wear and deformation resistance\u003c\/li\u003e\n\u003cli\u003eCore hardness Rockwell C50-58 for toughness under shear and load\u003c\/li\u003e\n\u003cli\u003eBlack luster finish for corrosion resistance and consistent surface appearance\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.8.2 and MIL-S-7742 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use dowel pin for precision alignment applications requiring a 0.5-inch diameter, 1.5-inch length spiral vent pull out configuration conforming to ASME\/ANSI B18.8.2 and MIL-S-7742 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal should be performed by qualified machinists or maintenance technicians familiar with precision fastener practices. Before installation, ensure the receiving bore is clean, properly sized, and free of burrs. Use an appropriate press or mallet with a driving block to seat the pin without side-loading. To remove, thread in the appropriate pull-out tool and extract axially to avoid bore damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1.5 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: 4000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Luster\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\u003eStandards\u003c\/strong\u003e: ASME\/ANSI B18.8.2, MIL-S-7742\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 04062\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51727700623666,"sku":"04062","price":17.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4955ec284bb4f415a6ba51d42917d975.jpg?v=1788681021","url":"https:\/\/voomisupply.com\/products\/holo-krome-04062-spiral-vent-pull-out-dowel-pin","provider":"Voomi Supply","version":"1.0","type":"link"}
