Value Collection MP40923 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION MP40923 is an extended prong cotter pin designed to secure fasteners, clevis pins, and shaft assemblies against loosening under vibration or load. Measuring 0.125 inches in diameter and 1.5 inches in length, this pin is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance. The extended prong design allows the legs to be bent back easily after insertion, locking the pin firmly in place. This type of fastener is a standard consumable in mechanical assembly, maintenance, and repair work across HVAC equipment, plumbing fixtures, and general industrial applications.

Extended prong cotter pins of this size are commonly used in residential and light commercial mechanical assemblies wherever a secondary locking fastener is required. Typical applications include securing clevis pins on linkage rods, retaining shaft pins on damper actuators and valve assemblies, and locking axle pins on carts and equipment dollies. The 0.125-inch diameter makes this pin compatible with standard drilled-hole fastener hardware in that bore size. Sold individually per package with a minimum order quantity of 50 units, making it suitable for stocking in service vans or shop inventory.

Key Features

• Extended prong design allows legs to be spread and bent back securely after insertion
• Grade 2 steel construction provides reliable tensile strength for light-duty locking applications
• Zinc-plated finish offers basic corrosion resistance in indoor and sheltered environments
• 0.125-inch diameter fits standard drilled-hole hardware in that bore size
• 1.5-inch length accommodates a range of pin and fastener thicknesses

Compatibility

Designed as a standard replacement or stocking cotter pin for use with any drilled clevis pin, shaft pin, or axle pin with a 0.125-inch bore hole requiring a secondary retaining fastener.

Installation Notes

Cotter pins are installed by inserting the pin through the drilled hole in the fastener or shaft, then bending the prongs apart and folding them back against the fastener to lock it in position. Always use a new cotter pin when reassembling a joint — never reuse a previously bent pin. Needle-nose pliers or a cotter pin puller are the standard tools for installation and removal. Ensure the host pin or shaft hole is clean and free of burrs before insertion.
