Value Collection 42546 Extended Prong Cotter Pin 4mm X 40mm

Product Description

The VALUE COLLECTION 42546 is an extended prong cotter pin used to secure clevis pins, shaft ends, and fastener assemblies in mechanical, agricultural, and industrial applications. Manufactured from Grade 2 steel with a zinc-plated finish, it provides corrosion resistance in moderately exposed environments. The pin measures 4mm in diameter with a 40mm usable length. Extended prong cotter pins are bent after insertion to lock a fastener in place, preventing loosening under vibration or dynamic load. Plumbers, maintenance mechanics, and field technicians commonly use this style of cotter pin when assembling linkages, valve stems, and clevis connections.

This cotter pin is suited for light-duty to medium-duty mechanical assemblies where a reliable, removable locking fastener is needed. Typical applications include HVAC equipment linkages, pump and valve assemblies, agricultural equipment, and general industrial machinery. The extended prong design provides additional material to bend over the retaining surface, making it easier to secure in thicker or offset mounting positions. Sold individually, this SKU is sourced in minimum order quantities of 200 units, making it practical for shop stock and service van inventory.

Key Features

• Extended prong design allows positive locking in thicker and offset retaining applications
• Grade 2 steel construction provides reliable tensile strength for light-duty to medium-duty use
• Zinc-plated finish resists corrosion in moderately humid or outdoor-exposed environments
• 4mm diameter and 40mm usable length suit a wide range of standard clevis and shaft-end configurations
• Removable and reusable design supports field servicing without special tools

Compatibility

Designed as an OEM-style replacement or service stock cotter pin for mechanical assemblies requiring a 4mm diameter extended prong fastener with a 40mm usable length.

Installation Notes

Installation requires no special tools beyond needle-nose pliers to bend the prongs after insertion. Always de-energize or shut down the equipment before servicing any pinned linkage or valve assembly. Insert the pin fully through the hole until the head seats against the mounting surface, then bend both prongs outward to lock. Do not reuse a cotter pin that has been straightened, as the material may be fatigued and prone to failure.
