Manufactured from Grade 8 alloy steel with a hardness of 50-58 HRC, this pin delivers high wear resistance and the load-bearing capacity required in demanding industrial and mechanical applications. At 5\/16 inch in diameter and 2.5 inches in overall length, it conforms to ASME B18.8.2 standards. The pin features one beveled end and one rounded end, which aids in controlled insertion and proper seating during assembly. Machinists, tool-and-die makers, and maintenance technicians working with jigs, fixtures, and precision assemblies are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis dowel pin is suited for use in metal fabrication, tooling, mold-making, and general machine assembly where tight positional tolerances are critical. The Grade 8 alloy steel construction makes it appropriate for high-stress environments where shear loads are a concern. Its double-shear breaking strength of 20,000 pounds supports use in heavy-duty fixture and die applications. The ASME B18.8.2 compliance ensures dimensional consistency across replacement and interchangeable applications in both production and maintenance settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction with 50-58 HRC hardness for high wear and shear resistance\u003c\/li\u003e\n  \u003cli\u003eASME B18.8.2 compliant for standardized dimensional interchangeability\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of 0.0002 inches for precision locating and alignment\u003c\/li\u003e\n  \u003cli\u003eDouble-shear breaking strength of 20,000 pounds for high-load applications\u003c\/li\u003e\n  \u003cli\u003eOne beveled end and one rounded end for controlled, damage-free insertion\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch diameter by 2.5 inches overall length — compact and versatile form factor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision replacement or original-installation dowel pin for jigs, fixtures, dies, molds, and machined assemblies that require ASME B18.8.2 compliant 5\/16-inch precision dowel pins.\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 mallet with a proper pin driver to avoid deforming the pin or bore. Always ensure the receiving hole is reamed to the correct tolerance before pressing the pin to prevent galling or damage to the bore surface. Inspect hole alignment before driving the pin fully seated. Do not apply lateral force to the pin after installation, as alloy steel pins at this hardness rating are resistant to bending but susceptible to brittle fracture under off-axis loading.\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: 2.5 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: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 50-58 HRC\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\u003eBreaking Strength\u003c\/strong\u003e: 20,000 pounds (Double Shear)\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163203\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: SF043043\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711978045746,"sku":"SF043043","price":15221.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef44187c7d7be05b08de57fd7f834bc9.jpg?v=1788482174","url":"https:\/\/voomisupply.com\/products\/value-collection-sf043043-precision-dowel-pin-5-16x2-5in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
