Manufactured from alloy steel to Material Grade 8, this pin meets ASME B18.8.2 dimensional and tolerance standards. It measures 5\/16 inch in diameter with an overall length of 1-1\/4 inches and holds a diameter tolerance of 0.0002 inches, making it suitable for close-tolerance fit applications. Hardness is rated at 50-58 HRC, and the pin is rated at 20,000 pounds breaking strength measured in double shear. One end is beveled and one end is rounded for guided insertion into precision-bored holes.\u003c\/p\u003e\n\u003cp\u003eThis dowel pin is used in tooling, fixture building, machining setups, and general mechanical assembly where repeatable part alignment is required. It is appropriate for both light industrial and heavy production environments. Machinists, tool-and-die makers, and maintenance technicians typically install these pins in drill-press or press-fit operations where hole location must be maintained across repeated assembly and disassembly cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction, Material Grade 8, for high-strength fastening applications\u003c\/li\u003e\n  \u003cli\u003e50-58 HRC hardness rating for wear and deformation resistance\u003c\/li\u003e\n  \u003cli\u003e20,000-pound double-shear breaking strength\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of 0.0002 inches for close-fit precision alignment\u003c\/li\u003e\n  \u003cli\u003eOne beveled end and one rounded end for controlled press-fit insertion\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.8.2 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.8.2 precision dowel pin for use in any mechanical assembly or fixture application requiring a 5\/16-inch diameter close-tolerance locating pin in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePrecision dowel pins are typically installed by machinists or maintenance technicians using an arbor press or hydraulic press fit. Confirm hole diameter and surface finish meet ASME B18.8.2 tolerances before installation to ensure proper fit. Do not hammer pins directly without a driver block, as this can cause damage to the pin end or the mating bore. Pins should be removed with a drift punch and press rather than by prying or twisting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Precision\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: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0002 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: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 50-58 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBreaking Strength\u003c\/strong\u003e: 20,000 pounds (Double Shear)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: One Beveled, One Rounded\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SF043040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701541568818,"sku":"SF043040","price":7796.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7507d6a43918448ca07d851db4fc210d.jpg?v=1788400974","url":"https:\/\/voomisupply.com\/products\/value-collection-sf043040-precision-dowel-pin-5-16-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
