Serrated Flange Nut Integrated Washer Vibration-Resistant U-Clip

Product features

The serrated flange u clip nut combines a serrated locking flange, an integrated washer and a U-shaped clip profile to deliver secure, vibration-resistant fastening in sizes from #6–3/4" and M5–M203 with M/UNC/UNF threads, manufactured to IFI-145/DIN standards in carbon, alloy and stainless steels or brass. Available in multiple strength grades (SAE J995 Gr.2,5,8; CL4–125) and finishes (plain, various zinc platings, black oxide, nickel, chrome, HDG), it offers corrosion resistance and high load capacity backed by comprehensive QA testing (calipers, go/no‑go gauges, tensile, hardness, salt spray, 3D inspection and magnetic flaw detection). Functionally tailored for structural steel, automotive, wind energy, oil & gas and machine assemblies, the serrated teeth prevent loosening while the integrated washer evens load distribution and the U-clip form enables quick, reliable panel retention and easy installation.
