The pin measures 5\/16 inches in diameter and 4 inches in usable length, with a zinc-plated finish that provides corrosion resistance in light-duty service environments. The extended prong design allows the legs to be bent back firmly after installation, creating a positive lock that resists vibration-induced loosening. Technicians and mechanics in HVAC, plumbing, and general industrial trades reach for this type of pin wherever a removable yet vibration-resistant fastening solution is required.\u003c\/p\u003e\u003cp\u003eThis cotter pin is suited for residential and light commercial maintenance work, equipment assembly, and field repairs. Typical applications include securing clevis pins on linkage assemblies, retaining shaft collars, and locking castellated nuts on threaded fasteners. The zinc plating makes it appropriate for indoor or sheltered outdoor use where minor moisture exposure is possible. This product is sold individually and is subject to a minimum order quantity of 50 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExtended prong design for a secure, vibration-resistant lock after installation\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction provides reliable strength for light-to-medium duty fastening\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish offers corrosion resistance in sheltered environments\u003c\/li\u003e\n\u003cli\u003e5\/16 inches diameter fits standard clevis pins and castellated nut applications of matching bore size\u003c\/li\u003e\n\u003cli\u003e4 inches usable length accommodates thicker assemblies requiring longer leg retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard extended prong cotter pin for use in mechanical assemblies, linkage systems, and equipment requiring a 5\/16 inches diameter pin with a 4 inches usable length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCotter pins are typically installed by maintenance technicians, millwrights, or HVAC service professionals using needle-nose pliers or cotter pin tools. Always insert the pin through a fully aligned hole and spread the prongs firmly against the fastener face to prevent backing out. Remove and replace the cotter pin any time a joint is disassembled — cotter pins are single-use fasteners and should never be straightened and reused. Ensure the mating pin or fastener is fully depressurized or de-energized before performing any work on the assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Extended Prong\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: 4 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 40958\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691574559026,"sku":"40958","price":35.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba2b9d793bd1916797f4bc8290ed8638.jpg?v=1788287195","url":"https:\/\/voomisupply.com\/products\/value-collection-40958-extended-prong-cotter-pin-5-16x4in","provider":"Voomi Supply","version":"1.0","type":"link"}
