Metric Steel Press-Fit Nuts for Sheet Metal

Often referred to as clinch style captive nuts, press these into a drilled or punched hole with an arbor press or similar pressure tool. Installation requires access to both sides of the panel. Knurls on the bottom of the nut hold them firmly in place. A zinc plating provides corrosion resistance in wet environments.

Metric Stainless Steel Press-Fit Nuts for Sheet Metal

Made from 18-8 stainless steel, these nuts have good chemical resistance and may be mildly magnetic. Also known as clinch style captive nuts, press these into a drilled or punched hole with an arbor press or similar pressure tool. Installation requires access to both sides of the panel. Knurls on the bottom of the nut hold them firmly in place.

Flush-Mount Press-Fit Nuts for Sheet Metal

A flat hex head sits flush against the material surface for use in low-clearance applications. Press them into a drilled or punched hole with an installation tool or an arbor press. Installation requires access to both sides of the panel. Made from 18-8 stainless steel, they're chemical resistant and may be mildly magnetic.

Heavy Duty Twist-Resistant Rivet Nuts

A hex-shaped body provides the highest twist resistance of any rivet nut. They're zinc plated for mild corrosion resistance. Install in a punched hole with a lever-style or power-driven rivet nut tool. The tool collapses the nut, creating a backside flange that holds the nut to the material. Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.
