1/4" x 1‑1/2" Coiled Spring Pins – High Carbon Steel, Plain

Deliver high strength and long‑term vibration resistance with durable 1/4" x 1‑1/2" coiled spring pins manufactured from high carbon steel. Featuring a multi‑coil design, these plain‑finish spring pins distribute load evenly across the hole diameter, reducing stress concentrations and increasing fatigue life compared to slotted pins. Ideal for automotive assemblies, industrial machinery, equipment repair, and heavy‑duty mechanical applications, they provide secure self‑retention, excellent shear strength, and reliable performance under repeated shock and vibration.
