Manufactured from Grade 2 steel with a zinc-plated finish, this pin measures 0.375 inches in diameter and 3 inches in usable length. The zinc plating provides basic corrosion resistance suitable for general-duty environments. Hammerlock-style cotter pins are favored by maintenance technicians and tradespeople who need a fast, tool-optional method of locking a pin in place without threaded fasteners or specialty tooling.\u003c\/p\u003e\n\u003cp\u003eThis cotter pin is commonly used in agricultural equipment, trailer hitches, HVAC equipment panels, pump linkages, and general mechanical assemblies where a positive-retention, removable fastener is required. It is appropriate for both light-duty field repairs and routine shop maintenance tasks. The hammerlock design allows the legs to lock around the fastener bore for a more secure hold compared to standard hairpin cotter styles, making it a practical choice in vibration-prone assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHammerlock design locks securely around the pin bore for reliable retention in vibration-prone applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate shear and tensile strength for general-duty fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion resistance for indoor and sheltered outdoor use\u003c\/li\u003e\n  \u003cli\u003e0.375 inch diameter and 3 inch usable length suit a wide range of standard clevis and shaft diameters\u003c\/li\u003e\n  \u003cli\u003eSold individually with a minimum order quantity of 5 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose hammerlock cotter pin for use in any mechanical assembly requiring a 0.375 inch diameter cotter pin with a 3 inch usable length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no specialized tools in most applications — the hammerlock legs are spread and locked by hand or with basic pliers. Always de-energize or shut down the mechanical system before servicing any pinned linkage or fastener assembly. Inspect the mating bore and clevis pin for wear or damage before inserting a new cotter pin. Do not reuse a previously installed cotter pin, as deformation during removal reduces holding reliability.\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: 0.375 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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163204\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: MP30555\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709835936050,"sku":"MP30555","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03950685109e960c93252435b9f1e884.jpg?v=1788461151","url":"https:\/\/voomisupply.com\/products\/value-collection-mp30555-hammerlock-cotter-pin-zinc-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
