It controls part ejection by providing a precise shoulder stop that limits pin travel and protects mold components from overload. The pin measures 5\/64 inch in diameter with an overall length of 10 inches, a pin length of 8 inches, and a shoulder diameter of 1\/8 inch with a 2-inch shoulder length. Constructed from steel with a nitride finish, it delivers hardened surface wear resistance suited to high-cycle mold environments. Toolmakers and mold technicians are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis shoulder ejector pin is used in plastic injection molds, compression molds, and die casting tooling where controlled ejection travel is required. The shoulder design allows the pin to seat against the ejector retainer plate, providing a positive stop and consistent ejection stroke. It is suited for both prototype tooling and production mold applications where precise pin positioning is critical to part quality and mold longevity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eShoulder design provides a positive stop against the ejector retainer plate for controlled pin travel\u003c\/li\u003e\n\u003cli\u003e5\/64 inch pin diameter with 1\/4 inch head diameter and 1\/8 inch head height\u003c\/li\u003e\n\u003cli\u003e8-inch pin length with 2-inch shoulder length for a 10-inch overall length\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shoulder diameter for accurate plate seating\u003c\/li\u003e\n\u003cli\u003eNitride finish increases surface hardness and wear resistance in high-cycle applications\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability under repeated ejection loads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shoulder ejector pin for use in injection molds and die casting tooling requiring a 5\/64 inch pin diameter and 10-inch overall length configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by toolmakers or mold technicians during mold build or maintenance. The mold must be fully cooled and all hydraulic or mechanical press pressure must be relieved before disassembling the ejector assembly. Pins should be inspected for straightness and surface condition before installation, and the ejector plate bores should be checked for proper fit to avoid binding during cycling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Shoulder Ejector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 5\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: HEP3529-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51723980112178,"sku":"HEP3529-G","price":23.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d418842bc1466756b860eff24f38a86.jpg?v=1788611009","url":"https:\/\/voomisupply.com\/products\/gibraltar-hep3529-g-shoulder-ejector-pin-5-64-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
