WHITWORTH Aerotight Nuts

Whitworth Aerotight nuts are high-quality self-locking nuts engineered to provide a secure and vibration-resistant fastening for BSW (British Standard Whitworth) threaded bolts and studs. Designed for use in traditional and heavy-duty applications, these nuts are ideal for classic vehicles, vintage machinery, and industrial equipment built with Whitworth threads.

Featuring a robust all-metal self-locking design, Aerotight nuts maintain consistent locking performance without the need for nylon inserts, washers, or chemical thread-locking compounds. This makes them ideal for environments subject to constant vibration or temperature changes. The locking action remains reliable even after repeated use, offering excellent long-term security and reduced maintenance costs.

At Arun Fasteners, we supply Whitworth Aerotight nuts in a range of sizes and finishes, all manufactured to the highest standards of strength and precision. Whether you’re restoring heritage equipment, maintaining workshop machinery, or working on vintage automotive projects, our Whitworth Aerotight nuts deliver dependable fastening performance with proven British engineering quality.
