Steel Press-Fit Nuts for Soft Metal and Plastic
Also known as broach style captive nuts, press these nuts into a drilled or punched hole in plastic and soft metal 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 tin plating provides corrosion resistance to chemicals and salt water.

Stainless Steel Low-Profile Rivet Nuts
The most corrosion resistant low-profile rivet nuts we offer, these stand up to chemicals. They're often used for light duty fastening in low-clearance applications. The threaded portion is drawn into the sleeve when installed, creating pressure against the hole to secure the nut. The tin-plating provides lubricity allowing the nut to collapse smoothly. Drill bit size listed in the table is for material with a 0.030"-0.090" thickness. These rivet nuts can be installed in thicker material, but may require larger holes. Install them using a hand- or power-driven rivet nut tool. Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.
