COUNTER NUT (PAL NUT)
COUNTER NUT DIN-7967 (PAL NUT)
📌 Overview
The Stainless Steel Counter Nut (PAL Nut) DIN 7967 is a thin lock nut with a prevailing torque feature, designed to prevent loosening under vibration or dynamic loads. Often used in combination with a standard hex nut, it provides additional security and locking capability, making it ideal for critical assemblies in machinery, automotive, and industrial applications.
Manufactured from SS304 (A2) and SS316 (A4) stainless steel, DIN 7967 PAL nuts offer excellent corrosion resistance, mechanical strength, and durability, ensuring reliable performance in harsh and high-vibration environments.
