It fits a 3\/16 inch (0.1875 inch) shaft diameter with a groove diameter of 0.147 inches and is manufactured from SAE 1060-1090 carbon steel with a yellow zinc dichromate finish for corrosion resistance. The ring measures 0.025 inches thick and features three prongs for positive engagement in the groove. Licensed tradespeople and assembly technicians working on small-shaft applications in HVAC, plumbing, and industrial equipment commonly specify this part for reliable axial retention without requiring special tools beyond standard pliers.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is suited for residential and light commercial mechanical assemblies where a low-profile, external groove retention solution is needed on shafts near 3\/16 inch in diameter. Typical applications include small motor shafts, pump components, fan assemblies, and instrumentation hardware. The E style design allows installation and removal with standard snap ring pliers, making it practical for field service and production-line assembly alike. The zinc dichromate finish provides a baseline level of corrosion protection appropriate for indoor or sheltered environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eE style external retaining ring for 3\/16 inch shaft diameter (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003eYellow zinc dichromate finish over SAE 1060-1090 carbon steel for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eGroove diameter of 0.147 inches with a tolerance of 0.0000 to 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.025 inches with tolerance of -0.002 to 0.002 inches\u003c\/li\u003e\n  \u003cli\u003eThree-prong design provides positive axial load retention\u003c\/li\u003e\n  \u003cli\u003eMeets SAE 1060-1090 and UNS G10600-G10900 fastener standards; manufactured under ISO 13485:2015\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style external E style retaining ring for 3\/16 inch shafts conforming to SAE 1060-1090 groove specifications.
