AB Tools Temporary Fasteners - Skin Pins - 3/32" (2mm)

Cleco fasteners are temporary fasteners used primarily in sheet metal work, especially in automotive restoration and aviation, to hold panels together during assembly, fitting, or repair before permanent fasteners are installed.

Yes, you need specialized cleco pliers designed to grip and operate the pins. These pliers pull the pin, creating the temporary clamping force.

This listing is for a pack of 10 cleco skin pins.

These 3/32" (2mm) cleco pins require a corresponding 3/32" (2mm) hole to be drilled in the panels.

No, cleco pins are designed for temporary holding only. Once the panel is finalized, they should be replaced with permanent fasteners like pop rivets, bolts, or the area can be welded.

They are best suited for sheet metal, particularly in automotive and fabrication contexts. Their effectiveness depends on the material thickness and the ability to drill the correct size hole.

Zinc coating provides a protective layer that helps prevent rust and corrosion, extending the life of the fastener, especially in environments exposed to moisture or the elements.

Ensure the hole is the correct size (3/32" or 2mm) and free of burrs. Check that you are using the correct type and size of cleco pliers and that they are functioning properly.

Verify that the pin is fully engaged and that the pliers have properly tensioned it. Check the thickness of the material; if it's too thin, the pin may not have enough purchase. Ensure the hole is not too large.

While zinc-coated, prolonged exposure to moisture can cause rust. Store pins in a dry location and clean them after use. Minor surface rust can often be cleaned off without affecting function.
