Value Collection CD553156 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION CD553156 is an extended prong cotter pin designed to secure fasteners, clevis pins, and linkage assemblies in mechanical and structural applications. Manufactured from Grade 2 steel with a zinc-plated finish, this cotter pin measures 0.25 inches in diameter and 3 inches in usable length. The extended prong design allows for quick bending and positive retention after installation, reducing the chance of vibration-induced loosening. Licensed tradespeople and maintenance technicians working on industrial equipment, agricultural machinery, HVAC linkage systems, and general mechanical assemblies will find this a reliable hardware staple.

This cotter pin is suited for residential and commercial maintenance applications where a standard-duty, corrosion-resistant fastener retention solution is required. The zinc plating provides a baseline level of rust resistance for indoor and sheltered outdoor environments. The 3-inch usable length accommodates thicker assemblies and applications where additional prong material is needed to complete the bend and lockout after insertion.

Key Features

• Extended prong design allows easy post-insertion bending for positive mechanical retention
• Grade 2 steel construction provides adequate shear strength for standard mechanical assemblies
• Zinc-plated finish offers baseline corrosion resistance in dry and sheltered environments
• 0.25-inch diameter and 3-inch usable length suit a wide range of clevis and linkage pin applications
• Lightweight at 0.01 pounds per pin, minimizing added weight in assembly

Compatibility

Designed as a standard-duty replacement or stock cotter pin for general mechanical assemblies requiring a 0.25-inch diameter extended prong style fastener retainer.

Installation Notes

Cotter pins are installed by mechanics, maintenance technicians, and tradespeople using standard needle-nose pliers or cotter pin tools. Always de-energize, depressurize, or mechanically lock the assembly before servicing any fastener. Insert the pin fully through the clevis or castle nut hole, then bend both prongs firmly against the fastener surface. Cotter pins are single-use fasteners and should not be straightened and reinstalled once removed.
