The AU-VE-CO PRODUCTS 18449 is a metric U nut designed for M6x1.00 screw thread applications where a floating or panel-edge fastener is needed. This extruded tapped hole U nut clips onto sheet metal panels ranging from 0.8 to 3.8mm thick, providing a captive threaded anchor point without welding or secondary operations. The black phosphate finish offers corrosion resistance and reduces galling during installation. The 13.5mm center-to-edge dimension positions the threaded hole consistently for repeatable assembly. HVAC technicians, auto-body fabricators, and sheet metal workers rely on this type of nut for quick access panels, equipment covers, and electrical enclosures.
This U nut is suited for light-gauge sheet metal assemblies in residential and commercial HVAC equipment, electrical panels, and mechanical enclosures. It installs by sliding or snapping onto the edge or flange of a panel, allowing an M6x1.00 fastener to be driven from the opposite side. The floating design tolerates minor hole misalignment, speeding up assembly on production lines or in the field. Trade professionals installing access panels, blower compartment covers, or control box lids will find this a direct fit for standard M6 panel-fastening applications.
Designed as an OEM-style replacement or service fastener for light-gauge sheet metal panels requiring M6x1.00 threaded retention in HVAC, electrical, and mechanical enclosure applications.
Installation does not require specialized tools - the U nut slides or snaps onto a panel edge or punched flange before the mating fastener is driven. Power down or de-energize any enclosure or equipment panel before removing or replacing access hardware. Ensure panel thickness falls within the 0.8 to 3.8mm range before seating the nut to prevent loose fit or thread damage. Minimum order quantity is 50 units per order.
