Value Collection 42522 Extended Prong Cotter Pin 2mm X 18mm

Product Description

The VALUE COLLECTION 42522 is an extended prong cotter pin designed for mechanical fastening applications where positive locking of bolts, shafts, clevis pins, and slotted fasteners is required. Manufactured from Grade 2 steel with a zinc-plated finish, this cotter pin measures 2mm in diameter and 18mm in usable length. The extended prong design allows the legs to be spread and bent securely after installation, locking the fastener in place and preventing backing out under vibration or repeated loading. Trades and maintenance professionals working on mechanical assemblies, fluid handling systems, and structural connections routinely use this style of pin as a low-cost, reliable locking solution.

This cotter pin is suited for use in residential and light commercial mechanical systems, as well as general industrial and trade applications. Common installation scenarios include securing slotted hex nuts on clevis linkages, retaining pins in hydraulic and pneumatic cylinder assemblies, and locking castle nuts on steering and suspension components. The zinc plating provides moderate corrosion resistance for indoor and sheltered outdoor environments. This SKU is sold as a single unit with a minimum order quantity of 200 pieces, making it appropriate for shop stock, service van inventory, or production assembly use.

Key Features

• Extended prong design spreads after insertion for positive mechanical lock
• Grade 2 steel construction provides reliable strength for standard fastening loads
• Zinc-plated finish offers moderate corrosion resistance in typical service environments
• 2mm diameter fits standard slotted and castle nut bore sizes in this metric range
• 18mm usable length accommodates a range of fastener thicknesses and shaft diameters

Compatibility

Designed as a standard metric extended prong cotter pin for use with slotted hex nuts, castle nuts, and clevis pin assemblies that accept a 2mm cotter pin bore.

Installation Notes

Installation is performed by inserting the cotter pin through the aligned bore of the fastener and spreading the prongs on the opposite side using needle-nose pliers or a cotter pin tool. Always de-energize, depressurize, or support any assembly before servicing the fastener it secures. Prongs should be bent in opposite directions against the fastener surface for maximum retention. Cotter pins are single-use fasteners and must be replaced with a new pin any time the assembly is disassembled.
