Black oxide coating is a chemical conversion coating process that converts the top layer of a metals to a naturally occurring black iron oxide. This black oxide coating provides a clean aesthetic finish with minimal change to thickness or dimensional tolerances (a low as five millionths of an inch). Also, this coating does not affect the sharpness of precision fastener components or increase the brittleness like some coatings.Fastener materials that can receive black oxide treatment include stainless steel, carbon steel, and non-ferrous metals, such as copper, under suitable conditions.
Black oxide cannot be produced over plated parts. In such cases, the plating must be stripped prior to the black oxide process. Adding a black oxide coating to metal fasteners provides both a decorative finish and protective barrier for added abrasion and corrosion protection. When treated with an after-finish, such as oil or wax, black oxide fasteners offer high levels of performance and dependability in mission-critical systems and applications.
Black oxide fasteners and U-bolts offer the following benefits and advantages:
U-Bolt-It not only offers high-quality fasteners that are designed and manufactured in a wide range of materials, we also offer specialty coatings to further enhance the performance properties of our fasteners. For example, our standard and custom black oxide U-bolts offer a protective barrier that enhances both the appearance and performance at a cost-competitive price compared to other finishes and coatings.
During the black oxide process, we pay careful attention to temperature, chemistry, and processing times to produce complete and uniform coverage of the entire surface of the fastener or part. Also, we can add after-finish to help determine the fastener configuration and end use. We offer black oxide coating to different fastener types, including:
Black oxide is often used where tight tolerances are required with minimal change to surface dimensions. Also, because of its clean aesthetic finish, it is also used for decorative purposes. Meeting high industry standards, our black oxide fasteners are used in a wide variety of industries, including:
U-Bolt-It offers high-quality, certified-engineering coating services to improve fastener performance and reliability and increase life span. We offer low friction, corrosion protection, and wear protection coatings that are tailored to your industry standards and applications. For example, our black oxide coatings do not add to part thickness, which allows it to retain its dimensional tolerances without affecting its sharpness.
Since 1988, we have been providing world-class customer service, quick turnaround times, and high-quality fastener products and components to a wide range of industries and applications. While we offer an industry-leading range of superior-quality fasteners, it is our extensive expertise and product knowledge that is the difference maker. Our team of professionals is dedicated to building a long-term customer relationship and providing valuable advice to help our clients pick the right fastener type, material, and coating for every application. Let us treat your next large batch or short run of premium fasteners with our in-house black oxidizing process.

"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."
