Value Collection MP40933 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION MP40933 is an extended prong cotter pin designed for use in mechanical assemblies where a positive, tamper-resistant fastening method is required. Manufactured from Grade 2 steel with a zinc-plated finish, this pin measures 5/32 inch in diameter and 2 inches in length. The extended prong design allows the legs to be bent outward after installation, locking the pin securely in place within a clevis, bracket, or shaft bore. The zinc plating provides a basic level of corrosion resistance suitable for light-duty indoor and outdoor mechanical applications. This type of fastener is installed by maintenance technicians, mechanics, and trade professionals across HVAC, plumbing, and general mechanical service work.

This cotter pin is suited for light-duty fastening applications in residential and commercial mechanical assemblies. Common uses include securing clevis pins in linkage assemblies, retaining shafts in brackets, and locking fasteners in low-vibration mechanical systems. The extended prong configuration provides additional bending material compared to a standard prong design, making it a practical choice where a more secure lock is needed after installation.

Key Features

• Extended prong design provides additional leg length for positive mechanical lockout after bending
• Grade 2 steel construction suitable for light-duty mechanical fastening
• Zinc-plated finish offers basic corrosion resistance for general service environments
• 5/32 inch diameter fits standard clevis pin and shaft bore applications
• 2 inch usable length accommodates a range of bracket and linkage thicknesses

Compatibility

Designed as a standard extended prong cotter pin for general mechanical fastening applications requiring a 5/32 inch diameter pin.

Installation Notes

Cotter pins are installed by inserting the pin through a pre-drilled hole in a shaft or clevis pin, then bending the extended prongs outward to lock the pin in position. Always ensure the mating hole diameter matches the pin diameter before installation. Use needle-nose pliers to bend the prongs cleanly without cracking the zinc plating. Do not reuse a cotter pin once it has been removed and the prongs bent, as the metal fatigues at the bend point.
