These screw-mount nuts have three mounting holes to accept screws and rivets. Insert the barrel through a hole or fasten the base with the barrel facing upward for use with thin materials. Since the base is flanged, it helps spread out the load. A larger base means more room for weight to spread. The longer the barrel, the more thread engagement with your screw.

Install threads without a drill or glue—simply peel off the backing and stick these nuts onto your part. They’re a good choice for quick jobs where you only need a light-duty hold, like prototyping. Use them on almost any surface, but keep in mind that the adhesive clings best to plastic, powder-coated metal, composites, and glass. If you need a stronger, permanent hold, choose an adhesive-ready nut instead.

Choose a larger baseplate for a stronger hold and a smaller baseplate when you need the nut to fit into a tighter space.

Adhere or mold these nuts onto a surface without gunking up the threads—the closed end blocks out adhesive, resin, and debris. It also acts as a stop, preventing screws from penetrating your material. Use them to add strong threads to material that’s too difficult and brittle to drill, such as acrylic and carbon fiber. They’re also often used when the surface is too thin to grip a threaded insert. To create a secure bond, large holes in the base let adhesive and resin flow and spread along the joint. Made of 316 stainless steel, these nuts resist corrosion from salt water and harsh chemicals.

The base of these nuts acts like a flange, distributing pressure evenly across the mounting surface. The larger the base, the more that pressure is spread out; the smaller the base, the tighter the space these nuts can fit into. Taller nuts engage more of a screw’s threads than shorter nuts. Shorter nuts fit in low-clearance areas.
