Machined from steel with a nitride finish for improved surface hardness and wear resistance, this pin measures 4.2 mm in diameter with an overall length of 250 mm and a pin length of 247 mm. The head measures 8 mm in diameter and 3 mm in height, providing a positive seating surface against the ejector retainer plate. Mold makers, toolroom machinists, and injection molding technicians install these pins as part of ejector plate assemblies in plastic injection molds.\u003c\/p\u003e\n\u003cp\u003eThis ejector pin is suited for use in injection mold bases across a range of cavity configurations in both production and prototype tooling. The nitride surface treatment reduces galling and extends service life in high-cycle applications. The 4.2 mm diameter and 250 mm overall length make it a fit for medium-depth mold components where a standard straight pin geometry is specified. Installation is performed by mold technicians and toolroom personnel during mold build or maintenance intervals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStraight ejector pin geometry for standard ejector plate assemblies\u003c\/li\u003e\n  \u003cli\u003e4.2 mm pin diameter and 247 mm pin length for medium-depth mold applications\u003c\/li\u003e\n  \u003cli\u003e8 mm head diameter and 3 mm head height for positive seating in retainer plates\u003c\/li\u003e\n  \u003cli\u003eSteel construction with nitride finish for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e250 mm overall length suits a variety of mold base depths\u003c\/li\u003e\n  \u003cli\u003eSold individually, minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for injection mold ejector plate assemblies specifying a straight ejector pin with a 4.2 mm pin diameter and 250 mm overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mold makers or toolroom technicians. Before servicing an ejector assembly, ensure the molding machine is locked out and all hydraulic pressure is relieved from the mold clamping system. Pins should be inspected for straightness and surface condition before installation, and the ejector bores in the mold should be checked for proper clearance fit. Do not force-fit pins into undersized bores, as this can cause premature wear or mold damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Straight Ejector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 4.2 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Length\u003c\/strong\u003e: 247 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 250 mm\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: MEP1029-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51721312567602,"sku":"MEP1029-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45452fc55458e6a6abc76214c4dc16ca.jpg?v=1788576264","url":"https:\/\/voomisupply.com\/products\/gibraltar-mep1029-g-straight-ejector-pin-4-2mm-250mm-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
