3/8" x 2" Coiled Spring Pins – High Carbon Steel, Plain

Deliver maximum strength and vibration resistance with heavy‑duty 3/8" x 2" coiled spring pins manufactured from high carbon steel. Designed with a multi‑coil construction, these plain‑finish spring pins distribute load evenly along the hole wall, reducing stress concentration and significantly improving fatigue life compared to slotted spring pins. Ideal for automotive assemblies, industrial machinery, equipment repair, and high‑load mechanical applications, they provide secure self‑retention, excellent shear strength, and long‑lasting performance under repeated shock and vibration.
