Press-Fit Nuts for Sheet Metal

Add permanent threads to thin panels in seconds. The knurls on these clinch-style nuts deform and grip sheet metal to create a permanent hold. Push them into a drilled or punched hole with an arbor press around your workpiece to install—no messy welding required.

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

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

High-Temperature High-Strength A286 Stainless Steel—Our strongest press-fit nuts are hard enough to install in stainless steel panels. They also withstand temperatures up to 1150° F and resist corrosion from chemicals such as bleach and chlorine.
