Hillman 15 Pcs U-Nuts (3/8"-16) | Extruded Speed Nuts for Automotive Panels & Sheet Metal | Steel Clip-On Fasteners for Quick Assembly, Industrial Hardware & Mechanical Applications

Product Description Hillman regular extruded U-nuts provide a reliable fastening solution for sheet metal assemblies and automotive hardware installations. Also known as speed nuts or clip nuts, these fasteners are designed to slide over the edge of sheet metal panels to create a threaded attachment point for screws or bolts. U-nuts are commonly used in automotive body panels, trim components, electrical enclosures, equipment housings, and industrial sheet metal assemblies where access to the backside of the material is not possible. The extruded design creates durable internal threads that match 3/8"-16 coarse-thread screws, allowing the fastener to securely engage the screw once installed. The U-shaped clip holds itself in place on the material, simplifying installation and making it easier to align the screw during assembly. Because they function as both a nut and a locking component, U-nuts help reduce hardware complexity while still providing reliable fastening performance. Manufactured from durable steel with a dark gray corrosion-resistant finish, these fasteners offer moderate protection against rust and wear while maintaining long-lasting performance in automotive and industrial environments. Packaged in a convenient refill box containing 15 extruded U-nuts, these fasteners are ideal for mechanics, automotive technicians, contractors, and DIY homeowners working on vehicle repairs, equipment installations, and sheet metal fastening projects. From the Manufacturer Extruded "U" Nuts are specialty nuts widely used for automotive purposes but also for various other industrial uses. They are durable and long-lasting with low maintenance, as well as easy to assemble. The steel construction provides corrosion resistance.
