Low-Profile Rectangular Weld Nuts

Weld permanent threads in channels and other tight spaces without adding a barrel bump that gets in the way. These nuts have a short barrel that tucks under low surfaces and a slim footprint that fits between narrow channel walls.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

18-8 Stainless Steel—Suitable for outdoor use, these nuts resist rust from water and mild chemicals. Weld them to stainless steel surfaces.

Number of Projections—More projections lead to more consistent welds by concentrating heat and protecting the threads from deforming.

Offset-Barrel Low-Profile Rectangular Weld Nuts

Add permanent threads on corners and near edges. With a slim base and a short, offset barrel, these weld nuts fit in tight spaces such as channels and low-clearance areas.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

Zinc-Plated Steel—A step up from plain steel, these nuts withstand occasional exposure to moisture. Weld them to uncoated steel surfaces. If MIG or TIG welding, grind the zinc plating off the part of the nut you intend to weld.

18-8 Stainless Steel—Suitable for outdoor use, these nuts resist rust from water and mild chemicals. Weld them to stainless steel surfaces.

Number of Projections—More projections lead to more consistent welds by concentrating heat and protecting the threads from deforming.

Weld Nuts

Add permanent threads to thin metal with our go-to weld nuts. Unlike press-fit and rivet nuts, these nuts fuse to the base metal, so they won’t twist and pull out. Three evenly spaced projections concentrate heat away from the threads to prevent them from deforming and create consistent welds. All have a collar pilot that guides the nut into the hole, holds it in place while welding, and protects the threads from weld spatter. You can also install them on thick pieces of metal.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

18-8 Stainless Steel—Suitable for outdoor use, these nuts resist rust from water and mild chemicals. Weld them to stainless steel surfaces.

Grade 2 Titanium—The best choice when you need a high strength-to-weight ratio, these nuts are 40% lighter than steel nuts. They’re also our most corrosion-resistant weld nuts, standing up to salt water, strong acids, and other harsh chemicals. Weld them to titanium surfaces.

Corner Weld Nuts

Create permanent, threaded 90° joints in sheet metal. Shaped like corner brackets, they’re often used to add mounting brackets in assemblies such as motors and heaters. These nuts have two projections that concentrate heat away from the threads to prevent them from deforming and create consistent welds.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

18-8 Stainless Steel—Suitable for outdoor use, these nuts resist rust from water and mild chemicals. Weld them to stainless steel surfaces.

Square Weld Nuts

With four symmetrical projections, these nuts create the strongest hold in our offering. Unlike rectangular weld nuts, each projection is equidistant from the threads, so welds wrap evenly for extra strength and twist resistance. Projections concentrate heat away from the threads to prevent them from deforming and create consistent welds. All nuts have a collar pilot that guides them into the hole, holds them in place while welding, and protects the threads from weld spatter.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

Rectangular Weld Nuts

These nuts add permanent threads in narrow spaces such as channels. With a slim footprint, they fit where round weld nuts can’t. Plus, their barrel is twice as long as low-profile barrels, so more threads connect with your bolt for a secure hold. You can weld these nuts in two orientations: on top of a flat surface or with the barrel sticking through a hole.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

18-8 Stainless Steel—Suitable for outdoor use, these nuts resist rust from water and mild chemicals. Weld them to stainless steel surfaces.

Number of Projections—Weld these nuts on top of metal—the projections on the bottom will fuse to the surface. More projections lead to more consistent welds by concentrating heat and protecting the threads from deforming.

Long-Barrel Round Weld Nuts

With an extended barrel and a round flange, these nuts distribute force evenly to prevent pull-through. The barrel is twice as long as standard round weld nuts, so more threads connect with your bolt for a great grip. You can weld these nuts in two orientations: on top of a flat surface or with the barrel sticking through the hole.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

18-8 Stainless Steel—Suitable for outdoor use, these nuts resist rust from water and mild chemicals. Weld them to stainless steel surfaces.

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.

Round Weld Nuts

With three projections and a short collar, weld these nuts under low-clearance areas without sacrificing strength. The projections concentrate heat away from the threads to prevent them from deforming and create consistent welds. To make welding easier, their collar pilot guides them into the hole and aligns them with the surface while also shielding the threads from weld spatter.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

18-8 Stainless Steel—Suitable for outdoor use, these nuts resist rust from water and mild chemicals. Weld them to stainless steel surfaces.

Two-Barrel Low-Profile Rectangular Weld Nuts

Fuse two threaded holes to metal with just one weld. These weld nuts have two short barrels with the same threads for installing screws side by side. They add the strength of two joints with a single nut. Their slim footprint fits in tight areas such as channels.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

Weld Locknuts

Prevent screws from backing out under heavy vibration. These nuts have distorted threads that grip screws tightly. Three evenly spaced projections concentrate heat away from the threads to prevent them from deforming and create consistent welds. These nuts also have a collar pilot that guides the nut into the hole, holds it in place while welding, and protects the threads from weld spatter.

Use Grade 2 or Class 6 screws to avoid stripping threads during installation. Distorted threads require high torque for fastening and unfastening, so you may need an impact wrench to remove screws.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

Left-Hand-Thread Tube End Weld Nuts

These weld nuts prevent fasteners from backing out of assemblies that rotate counterclockwise. Their left-hand threads pair with left-hand screws and rods to stop the fastener from loosening as the assembly turns. Weld them to the end of a tube for a stronger connection than tapping the tube directly. Also known as tube adapters and weldable threaded tube ends.
