U-nuts can attach two sheet-metal panels quickly and easily – in place of welding. The U-nut clips to the edge of one panel and stays in place as a screw is driven into the U-nut, securing the panels to each other. U-nuts can adjust slightly to accommodate panel misalignments.

U-nuts weigh less than other fasteners, yet still provide a strong, reliable hold. No special skills or tools are required for installation or removal.

Quick, one-hand installation or removal, allows for minor panel realignments, quality, on-time delivery & competitive pricing. Available for: sheet-metal screw sizes #4B to #14B, machine screw sizes 6-32 to ¼-20 & metric sizes M3 to M6.

Various styles, including: barbs on one or both legs, up-turned corner, straight upper leg, no extrusion on lower leg & relief notch and corners cut off. Various finishes, including: soluble oil, phosphate & oil, phosphate & water-based paint, zinc electroplate & water-based zinc coating.
