Machined from RC 60-70 spring steel with a zinc-plated finish, this pin delivers hardness and corrosion resistance suited for industrial and trade applications. The shaft diameter measures 5\/16 inches, overall length is 1.044 inches, and wire diameter is 0.047 inches. The locking ring diameter ranges from 0.32 to 0.33 inches, providing a positive retention fit when installed through a matching clevis pin or shaft.\u003c\/p\u003e\n\u003cp\u003eThis locking cotter pin is used across a wide range of mechanical, HVAC, and equipment-assembly applications where a positive-locking fastener is required. Common installation scenarios include linkage assemblies, valve stems, pump shafts, and equipment brackets where rotational or axial movement must be prevented. The zinc-plated finish offers light corrosion protection for indoor and sheltered outdoor environments. Packaged as a single unit with a minimum order quantity of 100 pieces, this pin suits both job-site use and stocking applications in maintenance shops and supply rooms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRC 60-70 spring steel construction for hardness and durability under mechanical load\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch shaft diameter with 0.047 inch wire diameter for precise fit\u003c\/li\u003e\n  \u003cli\u003eLocking ring diameter of 0.32 to 0.33 inches ensures positive retention\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.044 inches suits compact fastening applications\u003c\/li\u003e\n  \u003cli\u003eSold individually with a minimum order quantity of 100 units for shop stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock locking cotter pin for mechanical assemblies requiring a 5\/16 inch shaft diameter fastener with a 0.32 to 0.33 inch locking ring diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by maintenance technicians, millwrights, or licensed trade professionals as part of a larger mechanical assembly. Ensure the mating shaft or clevis pin hole is clear of debris and properly sized before insertion. De-energize and lock out any associated equipment before servicing fasteners in moving assemblies, per applicable OSHA lockout\/tagout requirements.
