WHITWORTH All Metal Locking Nuts

Whitworth all-metal locking nuts are precision-engineered fasteners designed to provide reliable, vibration-resistant locking for BSW (British Standard Whitworth) threaded bolts and studs. Unlike standard nuts, these all-metal lock nuts do not rely on nylon inserts or washers to maintain a secure hold, making them ideal for applications exposed to high temperatures, heavy vibration, or frequent maintenance cycles. Their robust design ensures consistent performance and long-term durability across multiple uses.

At Arun Fasteners, we offer a wide range of Whitworth all-metal locking nuts in various sizes and finishes, perfect for both industrial and classic machinery applications. These nuts are widely used in vintage vehicles, heritage equipment, and precision engineering projects, delivering a secure and reusable fastening solution that minimizes maintenance while maximising safety. Whether you are restoring a classic car or assembling heavy-duty machinery, our Whitworth all-metal locking nuts provide the strength and reliability you need.
