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.

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.

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—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.

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.

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.

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.

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.
