Aerotight® Nuts
Aerotight® nuts are precision-engineered, all-metal self-locking nuts designed to resist vibration, temperature extremes, and chemical exposure. Ideal for aerospace, automotive, marine, and industrial applications, they offer consistent locking performance without the need for inserts or additional components.
What's the benefit of Aerotight® Nuts?
- Proudly made in the UK.
- All-metal locking design – No nylon inserts, making them suitable for demanding applications.
- Temperature resistance – Far greater resistance to temperature than plastic locking rings.
- Chemical resistance – Some particularly harsh environments can break down nylon locking rings and require an all-metal design.
- Reusable – Maintains locking performance over multiple installations.
- Vibration-resistant – Proven performance in Junker vibration tests.*
- Corrosion-resistant – Available in A2 and A4 stainless steel for harsh conditions.
