Align off-center parts as you fasten them together—these steel press-fit nuts have floating threads, so you can install bolts at a slight angle. Zinc plating protects them from rust in wet environments. Use them to add permanent threads to sheet metal like weld nuts but without the setup and mess. Also known as clinch-style captive nuts, press them into a drilled or punched hole with an arbor press or similar pressure tool. The pressure forms your sheet metal into the knurls of the nut, making the nut inseparable from the sheet. Installation requires access to both sides of the panel.
