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.

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

Press-Fit Nuts for Soft Metals and Plastic

The ridged knurls on these broach-style nuts cut into soft metal and plastic without deforming them. They add permanent threads to everything from soft brass panels to brittle circuit boards.

Tin-Plated Steel—The plating resists corrosion from mild chemicals and salt water.

Closed-End Press-Fit Nuts for Sheet Metal

Fasten sheet metal without scratching or damaging nearby parts. The closed barrel on these nuts covers screws entirely once inserted and shields them from leaks and debris. Use them in electronics with sensitive components and CNC machines exposed to liquids and dust.

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

Press-Fit Locknuts for Sheet Metal

The nylon insert inside these nuts grips screws so they won't back out or loosen. Use them to keep thin parts fastened on engines and other vibrating machinery.

Steel—Best for dry environments since moisture will cause these nuts to rust.

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

Cadmium Yellow-Chromate-Plated Steel—Thread fasteners on these nuts smoothly without sticking. The plating also creates a stronger barrier against rust than zinc.

Self-Aligning Press-Fit Nuts for Sheet Metal

Fasten together parts with off-center holes. The threaded hole within these nuts shifts up to .01" in any direction, so screws pass through every time.

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

Thread-Masking Press-Fit Nuts for Sheet Metal

Shield internal threads from paint and debris during finishing processes. The removable rubber plug withstands high-temperature treatments such as powder coating. When you're ready to insert a screw, just push out the plug with a screwdriver or other tool.

Steel—Best for dry environments since moisture will cause these nuts to rust.
