Screw-Mount Nuts


These 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. The longer the barrel, the more thread engagement with your screw.
Zinc-plated steel nuts are corrosion resistant in wet environments.

Screw-Mount Nuts for Wood

These screw-mount nuts are often used to attach glides and levels to wood. Made from zinc alloy, they're corrosion resistant in wet environments.

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 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 nuts resist corrosion in industrial and saltwater environments, although will lose their corrosion resistance over 450° F. The cadmium plating also adds lubricity, making these nuts easy to install.
A286 stainless steel nuts are corrosion resistant. 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 nuts thread onto bolts smoothly.
