It measures 5\/16 inches in diameter and 3 inches in usable length, giving it a solid grip range for standard fastening tasks. Constructed from Grade 2 steel with a zinc-plated finish, this pin resists corrosion in moderate-exposure environments. The hammerlock design locks positively once installed, reducing the chance of unintentional release under vibration or lateral load. Maintenance mechanics, millwrights, and general contractors install this type of pin where a reusable, positive-lock fastener is required.\u003c\/p\u003e\n\u003cp\u003eThis hammerlock cotter pin fits standard applications across light industrial equipment, agricultural machinery, trailers, and general mechanical assemblies where a 5\/16-inch pin diameter is specified. It is sold in a package quantity of 25, making it practical for shop stocking or job-site use where multiple fastener points must be secured. The zinc plating provides adequate protection for indoor and sheltered outdoor service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHammerlock design provides positive retention once seated\u003c\/li\u003e\n  \u003cli\u003e5\/16 inches diameter fits standard clevis and shaft pin holes\u003c\/li\u003e\n  \u003cli\u003e3 inches usable length accommodates typical fastener stack thicknesses\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction balances strength and workability\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in moderate-exposure service\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 25 for shop stock or multi-point installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service stock cotter pin for mechanical assemblies requiring a 5\/16-inch hammerlock-style fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis pin is typically installed by maintenance mechanics or general tradespeople using basic hand tools. Always relieve load from the fastener assembly before removing or installing cotter pins. Ensure the pin hole diameter matches the 5\/16-inch pin body before installation to prevent stress or binding. Inspect the pin seating after installation to confirm the hammerlock has engaged fully before returning the assembly to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Hammerlock Cotter Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsable Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Grade 2 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: -38277-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51986739462450,"sku":"-38277-3","price":45.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/725435259212b158df5c9f4a2bdb5658.jpg?v=1789986392","url":"https:\/\/voomisupply.com\/products\/value-collection-38277-3-hammerlock-cotter-pin","provider":"Voomi Supply","version":"1.0","type":"link"}
