Buying advice

When choosing self-clinching nuts, consider material compatibility with your sheet metal (steel, stainless, aluminum), sheet thickness range, thread size, and environmental exposure. Popular PEM brand offers various types: Type PS4 for general steel, CLS for stainless, FH for flush, AS for lightweight, and PFT for floating alignment. Ensure the nut matches your installation tooling and desired performance (pull-out, torque, corrosion resistance). For high volume production, verify availability and cost per piece.
