Value Collection C207-CPS3122500 Cotter Pin 5/16 in 18-8 Ss

Product Description

The VALUE COLLECTION C207-CPS3122500 is an extended prong cotter pin manufactured from 18-8 stainless steel with a plain uncoated finish. It measures 5/16 inches in diameter and 2.5 inches in length. The extended prong design allows the legs to be bent back over a fastener or castle nut, providing positive retention and preventing axial movement in mechanical assemblies. At 0.01 pounds, this is a lightweight hardware component suited for use wherever corrosion resistance and reliable fastener locking are required. It meets ASME B18.8.1 dimensional standards and carries RoHS compliance, making it appropriate for industrial, marine, and trade service environments.

Extended prong cotter pins like the C207-CPS3122500 are used across a wide range of trade and industrial applications including HVAC equipment linkages, pump and valve assemblies, plumbing fixture hardware, and general mechanical installations. The 18-8 stainless steel construction resists rust and corrosion, making it a practical choice for outdoor, wet, or chemically exposed environments. Technicians typically use these in situations where a clevis pin, axle pin, or castle nut requires positive locking to prevent loosening under vibration or load.

Key Features

• Extended prong design for secure wrap-around retention after installation
• 18-8 stainless steel construction provides corrosion and rust resistance
• Plain uncoated finish — no coating to flake or interfere with fit
• Meets ASME B18.8.1 dimensional standard for consistent sizing
• RoHS compliant materials
• Lightweight at 0.01 pounds — minimal added mass to the assembly

Compatibility

Designed as a standard-dimension extended prong cotter pin per ASME B18.8.1, suitable for use in mechanical assemblies requiring a 5/16 inch diameter cotter pin for fastener retention.

Installation Notes

Cotter pins are installed by a qualified mechanic or technician after inserting them through the drilled hole of a pin or bolt and spreading the prongs to lock the assembly. Always ensure the receiving hole diameter is compatible before installation. Prongs should be bent fully around the fastener — do not leave prongs straight or only partially bent, as this reduces retention force. Single-use hardware: once removed, replace with a new cotter pin rather than reinstalling the used one.
