Slotted Spring Pin 420 Stainless (Inch)
Our Slotted Spring Pins made from 420 Stainless Steel are designed for high‑strength, wear‑resistant retention in mechanical and industrial assemblies requiring enhanced hardness and durability. Manufactured from martensitic 420 stainless steel, these spring pins provide significantly greater strength and wear resistance than standard stainless grades while offering corrosion resistance suitable for many industrial and controlled‑environment applications.
The slotted (tension pin) design allows the pin to compress during installation and then expand inside the mating hole, creating a strong interference fit without additional fastening hardware. This self‑locking action makes 420 stainless spring pins well‑suited for applications exposed to vibration, impact, and repeated motion where secure alignment and long service life are critical.
Engineered for demanding service conditions, our 420 Stainless Slotted Spring Pins are commonly used in machinery, automotive components, industrial equipment, gear assemblies, hinges, pulleys, linkages, and rotating mechanisms. The hardened stainless construction improves resistance to galling, deformation, and fatigue, supporting reliable retention under high‑stress operating conditions. Available in a wide range of diameters and lengths, these pins provide dependable performance for OEM manufacturing, maintenance, and repair applications where strength and precision are essential.
