Fasteners play a crucial, foundational role in the aerospace industry. Because they connect all primary and secondary structural areas in pressurized, non-pressurized, and load-transferring applications, they directly affect the structural weight, strength, and integrity of every aircraft and spacecraft.

Since 1988, U-Bolt-It has been a trusted single-source manufacturer and supplier of aerospace fasteners. We understand that in this industry, standard materials cannot withstand extreme atmospheric conditions. We supply specialty alloy and titanium fasteners engineered to deliver superior strength-to-weight ratios, helping make military and commercial aircraft lighter and more fuel-efficient without sacrificing safety.

Stringent Aerospace Performance Standards

Whether leaving the earth’s atmosphere or enduring the extreme temperatures of burning jet fuel, our specialty fasteners are developed to meet the most demanding aerospace requirements. Our hardware is engineered for:

Extreme Environmental Resistance: Exceptional oxidation and corrosion resistance in harsh atmospheres.
High Mechanical Strength: Maximum tensile, shear, and fatigue strength to endure extreme loads and vibrations.
Thermal & Pressure Stability: Superior performance across drastic temperature and pressure fluctuations.
Operational Security: Self-sealing and self-locking capabilities to prevent fluid leaks and mechanical loosening during flight.
Optimized Efficiency: High strength-to-weight ratios to minimize drag and reduce fuel consumption.

Frequently Asked Questions About Aerospace Fasteners

What materials are best for aerospace fasteners?

Aerospace applications require metals that are both lightweight and incredibly strong. The most common and effective materials are titanium, aluminum, high-grade stainless steel, and specialty superalloys like Inconel® and Hastelloy®.

What performance standards do aerospace fasteners need?

To keep an aircraft safe, fasteners must survive extreme environments. They are required to have high tensile and shear strength, resist severe corrosion, handle massive temperature changes, and stay locked tight during heavy, continuous flight vibrations.

Why are superalloys used in aircraft?

Standard metals can warp or weaken when exposed to the intense heat of a jet engine. Superalloys are required because they maintain their mechanical strength and structural integrity even under extreme heat, pressure, and atmospheric friction.

"We feel really happy working with you guys, it has been a short time business relationship but definitely we’ve received such a great service from your company that would be nice to keep working together. Junior is our contact point and there’s nothing but great things to say about his attentions. By the way, I truly loved the microfiber cloth. I’m always have a hard time to clean my glasses; I can use the one from U-bolt it without applying any liquid and just leaves them super clean. We appreciate your excellent service and looking forward to new projects. Kind regards and have a wonderful rest of the week."

"Our buyer received a letter from your company regarding an order I put in for some 3” stainless steel U-Bolts. I just wanted to thank you for the kind letter and let you know that your U-Bolts have been completely invaluable to us. We use them in the manufacturing process of an extremely sensitive product. Our previous U-bolts were zinc plated, therefore they became rusted too easily and risked the quality of the product. We hadn’t been able to find another U-bolt supplier with our specific size requirements (without going custom) until I came across your website! We are very grateful for the quality product you have sent us. We will definitely continue to use your company and the services provided."

"Debbie here from KKW in Mukwonago WI, just got the big u-bolts they look real good. They should work good for my project."

"I wanted to say how helpful it was to be able to order small quantities of screws from your business. As a start up business, without an established presence, it is virtually impossible to get small quantities of screws as samples. When we go into production, we will be ordering millions of screws, but we need to know that the same screws we test with our prototypes will be available at bulk prices at that time."
