Pal Nut

Pal Nuts are thin sheet-metal locknuts designed to prevent loosening of primary nuts under vibration and dynamic loads. They rely on spring-like action to grip the threads securely, acting as a secondary locking mechanism. Manufactured to ASTM and DIN standards, they are lightweight, cost-effective, and easy to install. They are commonly used in automotive, machinery, railways, and electrical applications as locknuts. Pal Nuts are valued for their simplicity and reliability in providing a vibration-resistant fastening solution.
