Value Collection P20281 Extended Prong Cotter Pin 5/16x3 in

Product Description

The VALUE COLLECTION P20281 is an extended prong cotter pin designed to secure clevis pins, bolts, and shafts in mechanical assemblies where a positive lock is required. At 5/16 inches in diameter and 3 inches in usable length, this pin is sized for medium-duty fastening applications. Constructed from 18-8 stainless steel with an uncoated finish, it resists corrosion in wet, outdoor, and mildly corrosive environments. Machinists, millwrights, maintenance technicians, and general tradespeople install this type of fastener across a wide range of industrial and commercial equipment.

This extended prong cotter pin is suited for use in agricultural equipment, material handling machinery, hydraulic cylinder assemblies, and general mechanical linkages where a standard cotter pin may not provide adequate retention. The extended prong design allows the legs to be bent back securely even in recessed or hard-to-reach pin holes, making it practical for field service and shop repair work alike.

Key Features

• Extended prong design provides positive locking retention in mechanical assemblies
• 18-8 stainless steel construction offers corrosion resistance without coatings or plating
• Uncoated finish suitable for applications where surface treatments could interfere with fit
• 5/16 inch diameter accommodates medium-duty shaft and clevis pin applications
• 3 inches usable length allows secure leg spread in deeper or recessed pin configurations

Compatibility

Designed as a standard replacement or service cotter pin for mechanical linkage, clevis, and shaft retention applications requiring a 5/16 inch diameter extended prong style fastener.

Installation Notes

De-energize and lock out all equipment before servicing any pinned mechanical connection. Insert the pin fully through the clevis or shaft hole so the eye seats flush, then spread the prongs with needle-nose pliers to lock the pin in place. Extended prong cotter pins are single-use fasteners and should be replaced rather than re-bent. Follow applicable equipment manufacturer guidelines and ANSI or OSHA lockout/tagout procedures during installation.
