Mil. Spec. Rivet-Mount Nuts

Create threads in hard-to-work areas—where you can’t reach the back of a workpiece, or material is too thin to be tapped. For a strong grip, these rivet-mount nuts have distorted threads that increase friction with bolts. Because they mount with two rivets, they won’t spin when you’re tightening screws. However, these nuts do move inside their retainers, which lets you install bolts at a slight angle; use them to align with off-center parts. All meet military guidelines for dimensions and material.
Cadmium-Plated Carbon Steel and Cadmium-Plated Steel—Cadmium-plated nuts resist corrosion in industrial and saltwater environments, although they will lose their corrosion resistance over 450° F. The cadmium plating also adds lubricity, making these nuts easy to install.
A286 Stainless Steel—A286 stainless steel nuts are corrosion resistant.
Silver-Plated A286 Stainless Steel—Silver-plated stainless steel nuts withstand temperatures up to 800° F. The silver plating also adds lubricity and prevents seizing caused by friction between nuts and bolts.
Lubricated—Lubricated nuts thread onto bolts smoothly.
