Depending on your specific application and environmental conditions, standard steel hardware can rust and degrade rapidly. Stainless steel offers a critical defense against atmospheric corrosion, harsh chemicals, and extreme temperatures.
U-Bolt-It manufactures and distributes a comprehensive variety of stainless steel fasteners, including custom U-bolts, structural bolts, transport chains, and hex nuts. From food processing facilities to highly corrosive offshore marine environments, we supply the exact grade of stainless steel required to ensure your assemblies remain secure, sanitary, and structurally sound.
Not all stainless steel is created equal. We offer fasteners in a variety of grades, each alloyed to provide specific advantages in strength, temperature tolerance, and corrosion resistance.
The most common class of stainless steel, prized for excellent corrosion resistance and non-magnetic properties.
Alloys designed to be hardened by heat treatment for high-strength applications.
Specific material specifications designated for high-temperature and high-pressure bolting.
We carry a vast inventory of standard hardware and custom-manufactured fasteners across multiple grades:
While both are highly corrosion-resistant, 316 stainless steel contains molybdenum. This addition drastically increases its resistance to chlorides, making 316 the mandatory choice for saltwater marine environments, offshore drilling, and harsh chemical processing. 304 is typically sufficient for standard atmospheric and indoor industrial exposure.
These are ASTM A193 specifications that denote fasteners designed specifically for high-temperature or high-pressure service. B-8 corresponds directly to the chemical makeup of 304 stainless steel, while B-8M corresponds to 316 stainless steel (due to the added molybdenum).
Standard austenitic grades (like 304 and 316) cannot be hardened by heat treatment—only by cold working. However, martensitic grades like 410 and 17-4 PH are specifically engineered to be heat-treated, offering much higher tensile strength and hardness for highly demanding structural applications.
Because we both manufacture and distribute fasteners, we control the quality of the hardware entering your supply chain. We understand the specific metallurgical requirements of the petroleum, aerospace, and food processing industries, ensuring you receive the exact alloy needed to prevent component failure.

"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."
