It fits shaft diameters from 5\/8 inch to 1 inch and measures 2-15\/16 inches in length with a wire diameter of 0.149 inches. Manufactured from Grade 2 spring steel with a plain steel finish, it delivers the resilience and retention force required for reliable fastening in vibration-prone environments. This type of cotter pin is a standard component in HVAC equipment linkages, pump assemblies, blower shaft connections, and general mechanical installations where a quick, tool-free retention method is needed.\u003c\/p\u003e\n\u003cp\u003eThe C3505 hair pin cotter is suited for light to medium-duty shaft retention in residential and commercial mechanical systems. Common applications include securing clevis pins on damper linkages, blower wheel hubs, belt-drive components, and pump shaft assemblies. The spring-steel construction allows the pin to snap into position and resist backing out under normal operating vibration. It is sold in a package quantity of 25, making it practical to stock for routine service and repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits shaft diameters from 5\/8 inch to 1 inch for versatile application coverage\u003c\/li\u003e\n  \u003cli\u003eGrade 2 spring steel construction provides consistent retention force and fatigue resistance\u003c\/li\u003e\n  \u003cli\u003eWire diameter of 0.149 inches balances flexibility with holding strength\u003c\/li\u003e\n  \u003cli\u003ePlain steel finish suitable for indoor and protected mechanical environments\u003c\/li\u003e\n  \u003cli\u003eTool-free installation and removal for fast field service\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 25 for shop stock and service van inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service replacement hair pin cotter for mechanical assemblies requiring a 5\/8 inch to 1 inch shaft diameter retention fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHair pin cotters are typically installed and removed by hand or with needle-nose pliers. Always de-energize equipment and relieve any mechanical tension on the shaft or linkage before removing or installing retention hardware. Inspect the pin seat and shaft groove for wear or burring before installing a new cotter. Follow applicable equipment manufacturer service procedures and relevant mechanical codes for the system being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter Range\u003c\/strong\u003e: 5\/8 to 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.149 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Grade 2 Spring Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain Steel\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: C3505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723935285554,"sku":"C3505","price":26.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0181f34e0df2df76bfc3f29834b40ba5.jpg?v=1788610227","url":"https:\/\/voomisupply.com\/products\/value-collection-c3505-hair-pin-cotter-spring-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
