Stainless 402 Spring Pins (Inch)

Our Stainless Steel 402 Spring Pins are high‑strength, corrosion‑resistant tension pins engineered for secure retention, precise alignment, and long‑lasting performance in demanding mechanical assemblies. Made from 402 stainless steel, these pins offer superior hardness and wear resistance compared to standard stainless grades, while still delivering dependable protection against rust, moisture, and environmental exposure.

Designed with a slotted, compressible body, these spring pins flex during installation and expand outward once seated, gripping firmly inside the mating hole. The 402 stainless alloy provides enhanced mechanical strength, making these pins ideal for assemblies subjected to repetitive motion, vibration, shock loading, or high‑stress conditions. Their clean stainless finish ensures durability in both indoor and outdoor environments.
