Types of Cotter Pins
Extended Prong Square Cut Cotter Pins (Zinc CR+3, Carbon Steel)
Extended prong square cut cotter pins are built for quick, secure fastening where durability and easy removal both matter. Their longer prongs allow for more reliable retention in larger assemblies, while the square cut ends provide a cleaner fit and stronger hold once bent into position. The zinc CR+3 plating protects against rust and oxidation, making these pins a trusted choice in agricultural, industrial, and mechanical maintenance applications.
Carbon Steel Cotter Pins (Zinc CR+3)
Carbon steel cotter pins offer dependable locking strength and everyday practicality. The zinc CR+3 finish enhances corrosion Resistant while maintaining a smooth surface for easy installation and removal. Commonly used to secure clevis pins, castle nuts, and shafts, these pins provide strong mechanical retention under vibration and load. Theyre an affordable, durable choice for general construction, machinery, and vehicle assembly work.
Stainless Steel Cotter Pins (SS300 Series)
Stainless steel cotter pins provide superior corrosion Resistant for environments where moisture or chemicals are present. Made from SS300 series stainless, they retain flexibility while resisting rust, making them ideal for marine, food service, and outdoor equipment applications. Their non-reactive nature and long lifespan make them the go-to option for demanding industries that prioritize reliability over replacement.
Clevis Pin and Cotter Pin Combinations (Plain)
Clevis and cotter pin combinations create a complete fastening solution that allows rotational movement while maintaining a secure mechanical link. The clevis pin provides the pivot, and the cotter pin locks it in place, ensuring stable operation even under dynamic loads. The plain finish keeps tolerances tight and installation simple, making this combination ideal for agricultural machinery, linkage systems, and adjustable mechanical assemblies.
Cotter Pins - Material Options
South Coast Fasteners stocks cotter pins in several material options suited for locking, securing, and fastening applications across mechanical, automotive, and industrial use. Whether you're pinning a clevis, anchoring hardware, or securing shafts and components, our cotter pins are built for strength and reliability across a variety of environments.
Stainless Steel 18-8
A versatile and corrosion-Resistant material for most general-purpose applications. 18-8 stainless steel cotter pins offer a clean finish and long-lasting durability, especially in mildly corrosive environments such as indoor assembly work, HVAC systems, and general manufacturing. They're ideal where both appearance and strength matter.
Stainless Steel 300
This broader classification of stainless steel includes multiple grades designed for strength and Resistant to oxidation and moisture. Stainless 300-series cotter pins provide added Resistant in damp or semi-corrosive conditions, making them a go-to in outdoor assembly, marine equipment, and structural applications that demand non-rusting performance.
Steel
Steel cotter pins are cost-effective and widely used in everyday fastening and retaining tasks. With a strong base material that holds its shape under stress, plain steel cotter pins are ideal for non-corrosive indoor environments or temporary assemblies where value and rigidity are more imporPant than weather Resistant.
Cotter Pins - Available Finishes
Each finish is designed to meet different performance Standards, from rust protection to visual consistency. South Coast Fasteners offers cotter pins in:
Plain
A raw, uncoated finish best for dry environments or when the pin will be coated or painted after installation. Plain cotter pins are easy to bend and install, commonly used in machinery, light automotive work, and general-purpose equipment.
Zinc CR+3
This finish adds a layer of corrosion Resistant with a clean, silver appearance. Zinc-plated cotter pins are a popular choice for hardware exposed to light moisture, mild chemicals, or general outdoor use. The coating protects the steel beneath from rusting prematurely, extending the life of the assembly
