Steel Press-Fit Nuts for Soft Metal and Plastic

Also known as broach-style captive nuts, these steel nuts add permanent threads to soft metal and plastic panels. Press them into a drilled or punched hole with an arbor press or similar pressure tool. The pressure forces the panel into the knurls of the nut, keeping the nut firmly in place. Installation requires access to both sides of the panel. They are tin plated to resist corrosion from 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.
