It features a 5\/16-inch pin diameter and a 6-inch overall length (OAL), with a usable pin length of 5.75 inches. The pin is manufactured from steel and carries a hard pin hardness rating, making it suitable for applications that demand resistance to deformation under load. A 1\/2-inch head diameter and 1\/4-inch head height provide a positive stop during insertion. Machinists, maintenance mechanics, and tool-and-die technicians are the primary installers of this type of component.\u003c\/p\u003e\n\u003cp\u003eHard core pins in this size range are commonly used in jigs, fixtures, tooling setups, and machine assembly where precise alignment or retention is required. This pin suits both light industrial and heavy-duty mechanical applications where a hardened steel pin is specified. It installs in pre-drilled or reamed holes sized to accept a 5\/16-inch diameter pin. Typical settings include manufacturing facilities, machine shops, and maintenance environments where repeatable component alignment is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch pin diameter for standard tooling and fixture compatibility\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 5.75-inch pin length for deep-reach installations\u003c\/li\u003e\n  \u003cli\u003eHard pin hardness rating resists deformation under load and repeated use\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch head diameter provides a positive stop and prevents over-insertion\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch head height keeps the profile low in space-constrained assemblies\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in industrial and mechanical environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hard core pin for use in jigs, fixtures, tooling plates, and mechanical assemblies requiring a 5\/16-inch diameter hardened pin with a 6-inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance mechanics using standard hand or arbor press equipment. The receiving hole should be properly sized and deburred before pin insertion to ensure correct seating and avoid galling. Always de-energize or lock out any machinery before installing or removing alignment pins per applicable LOTO procedures. Do not strike the head with an unprotected steel hammer if surface finish or pin concentricity is critical.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Hard Core\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Length\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Hardness\u003c\/strong\u003e: Hard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HCP5653-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51721814802738,"sku":"HCP5653-G","price":17.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c43b2b3fc4ff4a9eb308541a2f8b7c66.jpg?v=1788581345","url":"https:\/\/voomisupply.com\/products\/gibraltar-hcp5653-g-hard-core-pin-5-16-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
