SPRING DOWEL PIN
SPRING DOWEL PIN (SLOTTED SPRING PIN)ISO-8752
📌 Overview
The Stainless Steel Spring Dowel Pin (Slotted Spring Pin) is a high-performance fastening component designed to secure, align, or join machine components while providing flexibility and vibration resistance. Its slotted, hollow cylindrical design allows the pin to compress during installation, creating a firm grip in pre-drilled holes without additional fastening hardware.
Manufactured from SS304 (A2) and SS316 (A4) stainless steel, these pins deliver excellent corrosion resistance, high fatigue strength, and long-term durability, making them ideal for industrial machinery, automotive, marine, and outdoor applications.
