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-Aligning Rectangular Weld Nuts

Help screws pass through perfectly every time. These nuts float inside a rectangular retainer that shifts and tilts to compensate for misalignment. A pilot tip locates the hole, and the retainer holds the nut in place during welding.

Steel with Steel Retainer—Best for dry environments since moisture will create rust. Weld them to steel surfaces.

Zinc-Plated Steel with Steel Retainer—A step up from a plain steel nut, the zinc plating on these nuts withstands occasional exposure to moisture. Weld them to uncoated steel surfaces.

Zinc-Plated Steel with Aluminum Retainer—Both the nut and retainer can withstand occasional exposure to moisture. Weld them to aluminum surfaces.

18-8 Stainless Steel with Stainless Steel Retainer—Suitable for outdoor use, both the nut and its retainer resist rust from water and mild chemicals. Weld them to stainless steel surfaces.

Self-Aligning Press-Fit Locknuts for Sheet Metal

Fasten together unaligned parts and keep screws in place. The threaded hole within these press-fit nuts shifts up to .01" in any direction, so you can fasten together thin panels with off-center holes. The irregularly shaped threads tightly grip screws to prevent them from loosening or backing out under vibration.

18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust and mild chemicals.

Steel Snap-In Nuts

Snap these nuts—also known as cage nuts—into square holes in thin material. They’re often used to mount servers and other equipment in electronics racks. Threads float inside the cage, so you can fasten a bolt at a slight angle to align off-center parts. Mounting legs expand to lock these nuts in place.

Install these nuts by hand, with pliers, or with a snap-in nut installation and removal tool.

Rectangular with Floating Nut

Phosphate-Coated Steel—Phosphate-coated steel nuts are mildly corrosion resistant in dry environments.

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

Stainless Steel Snap-In Nuts

For excellent corrosion resistance in most environments, these nuts are made of 18-8 stainless steel. Snap them into square holes in thin material, and the mounting legs expand to lock them in place. Also known as cage nuts, the threads float inside the cage, so you can fasten a bolt at a slight angle to align off-center parts. These nuts are often used to mount servers and other equipment in electronics racks. They may be mildly magnetic.

Install these nuts by hand, with pliers, or with a snap-in nut installation and removal tool.

Easy-Install Snap-In Nuts

Pinch the flexible nylon casing of these nuts to add threads to thin metal. Unlike typical rigid snap-in nuts, these squeeze into a square hole from the front or back of your material. Once installed, they stay put. They meet EN 61373, so they’re certified for use in environments with heavy vibration—think a bumpy railcar. NEBS GR-63-CORE tested, they’ve also passed earthquake simulations. In your facility, this means you can trust them to hold tight to sensitive equipment, like the servers suspended on your electrical racks.

Also known as cage nuts, they come in two parts—the cage and the nut—that you combine before installation. Threads float inside the cage, so you can fasten a bolt at a slight angle to align with off-center parts.

Self-Aligning Key-Locking Threaded Inserts for Soft Metal

Align threads with off-center parts. These inserts have floating threads that shift slightly so you can insert screws at a slight angle as you fasten two parts together. They're comparable to Keensert inserts.

To install, drill and tap a hole in your material. Then, thread the insert onto the installation tool and screw it into the hole. Place the tool over the keys and hit it with a hammer to drive them in.

Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.

Thin Wall—Use these inserts near the edge of workpieces or wherever you only have space for a small hole. They're also lighter than standard and extra-thick wall inserts for applications with strict weight limitations.

High-Strength Cadmium-Plated Alloy Steel—These inserts have the strength to stand up to high-pressure applications and a plating that helps screws thread in smoothly.

18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

Clip-On Nuts for Flanged Edges

Slide these nuts on the edge of a panel and position them by hand. Also known as G-style clip-on nuts, they have threads that float inside the retainer so you can install a bolt at a slight angle to align off-center parts.

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

Black Phosphate-Coated Steel—Black phosphate-coated steel nuts are mildly corrosion resistant in dry environments.

Grounding Snap-In Nuts

Pave a safe path for electricity—these snap-in nuts dig into the mounting surface and cut through coatings to touch the metal below for a proper ground. They’re often used to mount servers and other equipment into electronics racks. All meet EIA-310 (Electronic Industries Alliance) specifications for use in standard 19" electronics racks. Simply snap these nuts, also known as cage nuts, into square holes.

These snap-in nuts have a flexible nylon casing, so you can install them with a pinch. Unlike rigid snap-in nuts, you can squeeze them into a hole from either side. As you fasten a bolt, the nut in the casing is pulled up, pushing its teeth into the mounting surface.
