Value Collection 40953 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION 40953 is an extended prong cotter pin designed to secure fastener assemblies, clevis joints, and slotted nut applications across a wide range of mechanical and structural installations. Manufactured from Grade 2 steel with a zinc-plated finish, this cotter pin measures 0.25 inches in diameter and 6 inches in usable length. The extended prong design allows the legs to be bent back around a fastener with greater leverage and holding surface than standard cotter pins, reducing the chance of vibration-induced back-out. Machinists, millwrights, and maintenance technicians are the primary installers of this hardware type.

This cotter pin is suited for use in agricultural equipment, material handling machinery, trailer hitches, hydraulic cylinder clevis ends, and general industrial fastening applications. The zinc plating provides a base level of corrosion resistance suitable for indoor and light outdoor environments. At 6 inches in length, the pin accommodates through-holes in heavier shafts and thicker assemblies where a standard-length cotter pin would fall short. It is sold individually, with a minimum order quantity of 50 units.

Key Features

• Extended prong design provides increased bend-back leverage for secure retention
• Grade 2 steel construction for reliable shear performance in mechanical fastening
• Zinc-plated finish offers basic corrosion resistance for light-duty environmental exposure
• 0.25 inch diameter suits standard clevis and slotted-nut hole patterns in that size range
• 6 inch usable length accommodates thick shaft assemblies and extended clevis applications

Compatibility

Designed as a general-purpose extended prong cotter pin for mechanical assemblies requiring a 0.25 inch diameter pin in agricultural, industrial, and trailer fastening applications.

Installation Notes

Cotter pins are typically installed by maintenance technicians and millwrights using needle-nose pliers or cotter pin tools. Always de-energize, lower, or block any load-bearing assembly before servicing the joint. Insert the pin fully through the hole, then bend one or both prongs back against the fastener face to lock it in place. Do not reuse a previously bent cotter pin, as bending fatigues the metal and reduces holding reliability.
