spring , Iran

A spring pin is a mechanical fastener used to secure components and absorb shear stress and vibration in industrial assemblies. The outer diameter typically ranges from 1 to 50 mm, and length is designed from 5 to 200 mm. Common materials include carbon spring steel, stainless steel, or fatigue resistant alloys. Surface hardness after heat treatment ranges from 45 to 55 HRC. The slotted or grooved structure provides elasticity and reliable locking capability. The surface is protected with phosphate, galvanized, or black oxide coating for corrosion resistance.

Structurally, spring pins are manufactured through precise bar cutting, cylindrical forming, longitudinal slot creation, and stress relief heat treatment at 250 to 450°C. Grinding and surface finishing ensure dimensional accuracy up to ±0.01 mm. Shear strength and compression tests evaluate mechanical performance. These components are designed according to ISO 8752 and DIN 1481 standards. Spring pins are widely used in automotive, industrial machinery, mechanical equipment, and precision assemblies.You can order and buy spring from Iran by contacting us through whatsaap and email.

How to Select the Proper Spring Pin Size in iran

To select the proper spring pin size, first measure the installation hole diameter and applied load accurately. The spring pin diameter should typically be 0.1 to 0.3 mm larger than the hole diameter to ensure a secure fit. The pin length must match the component thickness and hole depth to provide uniform stress distribution. The spring pin material should be selected based on operating conditions, environmental humidity, and vibration level. Using hardened spring steel increases shear strength and connection lifespan. Following these criteria ensures safe installation, prevents looseness, and provides stable mechanical performance.
