METAL LOCK NUT
METAL LOCK NUT DIN-980
📌 Overview
The Stainless Steel Metal Lock Nut DIN 980 is a thin hex nut with a prevailing torque feature, designed to provide vibration-resistant fastening without the need for additional locking devices. It is commonly used where space is limited, offering reliable locking performance in thin sheet metal assemblies, machinery, and structural applications.
Manufactured from SS304 (A2) and SS316 (A4) stainless steel, DIN 980 metal lock nuts offer excellent corrosion resistance, mechanical strength, and long-term durability, making them ideal for automotive, machinery, electrical, and industrial applications.
