Manufactured from Grade 8 alloy steel, it delivers a Rockwell hardness of 50-58 HRC, providing high resistance to wear and shear forces. The pin measures 5\/16 inch in diameter and 1\/2 inch in overall length, with a diameter tolerance of 0.0002 inches for tight, repeatable fits. One end is beveled for guided insertion, and the opposite end is rounded. A rated breaking strength of 20,000 pounds in double shear confirms the load capacity expected from a Grade 8 fastener. Machinists, toolmakers, and precision fabricators install this pin in jigs, fixtures, dies, and mating bores.\u003c\/p\u003e\n\u003cp\u003eThis pin is suited for industrial and manufacturing applications where precise hole-to-hole alignment is critical. Typical installations include machine tool fixtures, die sets, assembly jigs, and other tooling where repeatable positional accuracy must be maintained under load. The compact 1\/2 inch length makes it well suited for shallow through-bores and blind-hole applications in metal fabrication and production machining environments. It conforms to ASME B18.8.2, the standard governing ground machine dowel pins used across general metalworking trades.\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 wear and shear resistance\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of 0.0002 inches for precision interference or transition fits\u003c\/li\u003e\n  \u003cli\u003eBreaking strength of 20,000 pounds measured in double shear\u003c\/li\u003e\n  \u003cli\u003eOne beveled end and one rounded end for controlled insertion and positive seating\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.8.2 standard for ground precision dowel pins\u003c\/li\u003e\n  \u003cli\u003eCompact 5\/16 inch diameter by 1\/2 inch length for shallow-bore fixture applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.8.2 precision ground dowel pin for use in machined holes requiring a 5\/16 inch diameter pin with 0.0002 inch diameter tolerance, suitable for jigs, fixtures, dies, and general metalworking assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePrecision dowel pins are typically installed by machinists or toolmakers using an arbor press or soft-faced mallet to avoid surface damage. Always verify bore diameter and finish before installation to confirm the correct fit class. Pins should not be driven into undersized or unfinished holes, as this can damage the pin geometry and reduce alignment accuracy. Inspect mating bores for burrs, chips, or contamination before pressing the pin into position.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\/2 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\u003eBreaking Strength\u003c\/strong\u003e: 20,000 pounds (double shear)\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\u003eFastener Standard\u003c\/strong\u003e: ASME B18.8.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Precision\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: SF043037\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714159018290,"sku":"SF043037","price":5977.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96895720d3a03691c4f273603df6b279.jpg?v=1788496977","url":"https:\/\/voomisupply.com\/products\/value-collection-sf043037-precision-dowel-pin-5-16x1-2-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
