Manufactured from Grade 4000 alloy steel with a black luster finish, this pin measures 5\/16 inch in diameter and 2.5 inches in overall length. One end is beveled for guided insertion and the opposite end is threaded for pull-out removal, making extraction clean and controlled without damaging the bore. It conforms to MIL-S-7742 fastener standards. Machinists, maintenance technicians, and tool and die professionals are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis dowel pin is suited for use in jigs, fixtures, tooling plates, and precision-machined assemblies where repeatable alignment and positive location are required. The spiral vent groove allows air and fluid to escape during press-fit installation, reducing hydraulic lock and easing assembly. Typical applications include machine tool components, die sets, and industrial equipment where controlled disassembly is a recurring maintenance requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral vent groove prevents hydraulic lock during press-fit installation\u003c\/li\u003e\n  \u003cli\u003eThreaded end allows pull-out removal without bore damage\u003c\/li\u003e\n  \u003cli\u003eBeveled end provides guided entry into close-tolerance holes\u003c\/li\u003e\n  \u003cli\u003eGrade 4000 alloy steel construction for strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eBlack luster finish for corrosion inhibition during storage and service\u003c\/li\u003e\n  \u003cli\u003eMeets MIL-S-7742 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-install component for precision alignment applications requiring a 5\/16 inch spiral vent pull out dowel pin conforming to MIL-S-7742.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using an arbor press or appropriately sized driver to seat the pin without impact damage to the bore. Ensure the receiving hole is clean, deburred, and dimensioned to the correct tolerance before installation. The threaded end requires a properly sized pull-out tool or bolt for extraction during disassembly. Do not exceed the designed interference fit for the bore material.\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: 5\/16 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: 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: Beveled and Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: MIL-S-7742\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.054 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 04038\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51730609013042,"sku":"04038","price":29.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6f5580040fa80e1ee438d5abebe916f_103323c9-98f2-45c2-b0f5-a587747e1ae8.jpg?v=1788720264","url":"https:\/\/voomisupply.com\/products\/holo-krome-04038-spiral-vent-pull-out-dowel-pin-5-16x2-5in","provider":"Voomi Supply","version":"1.0","type":"link"}
