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.

Lightweight Aluminum—At one-third the weight of steel, use these nuts in robotics, aerospace parts, and other applications with strict weight limits. They resist rust about as well as stainless steel but aren't as strong, so they're best for installation in aluminum panels.
