Style A	Style B

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.

Zinc-Plated Steel—Zinc-plated steel nuts resist corrosion in wet environments.

Style B—Style B nuts can also be welded for a stronger, permanent hold. The three projections on their base concentrate your weld and create room for heat to dissipate, protecting threads from deforming.

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.

A286 Stainless Steel—A286 stainless steel nuts are corrosion resistant.

Cadmium-Plated Carbon Steel and Cadmium-Plated Steel—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.

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.

Self-Tapping Adhesive Snap-In Standoffs


Center Mounting Hole	Corner Mounting Hole

Tightly mount circuit boards without drilling. Stick these standoffs to flat surfaces using the adhesive backing. Then, a screw cuts threads into the standoff as you drive it in, creating a tight hold. These standoffs are made of plastic, so they're nonconductive and won't allow electrical currents to pass between circuit boards. Also known as snap-in supports.

Nylon 6/6—Lightweight and stand up to daily wear and tear. Nylon swells and weakens when exposed to moisture, so these standoffs are best for dry environments.
