NITHA AEROSPACE PRIVATE LIMITED
By Nitha Aerospace Private Limited – Pioneering Indigenization in Critical Fasteners
In aerospace, every component matters – but the smallest can often be the most critical. Self-locking nuts may seem simple, yet they are trusted to secure engines, fuselage assemblies, and spacecraft systems where failure is not an option.
At Nitha Aerospace Pvt Ltd , we design and manufacture aerospace-grade self-locking nuts that perform under extreme vibration, thermal cycling, and high dynamic loads . Made in India, trusted globally, our locknuts are precision-engineered from aerospace superalloys like Titanium, Inconel, and A286 stainless steel , and manufactured to AS, NASM, MS, and MIL-SPEC standards .
Self-locking nuts (or locknuts) feature an integrated locking mechanism – metallic or non-metallic – that prevents loosening due to vibration or torque. Unlike standard nuts, they maintain preload even under turbulent flight conditions, high temperatures, and repeated load cycles .
In aerospace manufacturing, these nuts are produced with tight tolerances, certified materials, and advanced coatings to ensure long-term performance and reliability.
Aerospace locknuts demand materials that combine strength, temperature resistance, and corrosion protection.
Titanium Grade 5 (Ti-6Al-4V) – Lightweight, high strength, corrosion-resistant
Inconel 718 / 625 – Exceptional at 700°C+, ideal for engines
A286 Stainless Steel – Excellent high-temperature capability
Alloy Steel (Plated) – High strength with protective coatings
Cadmium Plating – Corrosion protection in marine & aerospace environments (restricted in some regions)
Dry Film Lubricants (MoS₂) – Reduce friction & galling in high-torque assembly
Aerospace-grade locknuts fall into two main categories:
Nylon collar provides thread grip
Limited to low-heat applications
Distorted Thread Type – Interference fit for vibration resistance
Elliptical / Crown Lock Nuts – Engineered deformation for secure fit
Collar Nuts – Used in high-heat engine zones
We manufacture in full compliance with:
AS (Aerospace Standard)
NASM (National Aerospace Standard Metric)
We manufacture in full compliance with:
Vibration Resistance – Maintain preload in the harshest conditions
Thermal Stability – Operate flawlessly above 700°C
Weight Efficiency – Titanium versions reduce aircraft mass without compromise
Corrosion Protection – Built to survive marine & tropical climates
Zero Re-Torque Design – All-metal designs remain secure for the long term
Before choosing, consider:
Application temperature range
Frequency of disassembly
Material compatibility (avoid galvanic corrosion)
Required preload & torque
Applicable aerospace standards
Pro Tip: Avoid nylon insert nuts in high-heat or fuel-exposed zones — choose all-metal variants instead.
At Nitha Aerospace Pvt Ltd , we manufacture mission-critical aerospace fasteners designed for absolute reliability . From fighter jets to satellites, our self-locking nuts are precision-engineered in India for global aerospace performance.
When your assembly depends on the smallest component, choose a partner who understands that in aerospace, there are no second chances.
