5/16" x 2" Coiled Spring Pins – High Carbon Steel, Plain

Deliver exceptional strength and vibration resistance with durable 5/16" x 2" coiled spring pins manufactured from high carbon steel. Featuring a multi‑coil construction, these plain‑finish spring pins distribute load evenly within the hole, reducing stress concentration and significantly improving fatigue life compared to slotted spring pins. Ideal for automotive assemblies, industrial machinery, equipment repair, and heavy‑duty mechanical applications, they provide secure self‑retention, high shear strength, and reliable long‑term performance under repeated shock and vibration.
