Cleco Fastener Kit – 50 Sheet Metal Pins (1/8″) & 10 Side Grip Clamps (1″ & ½″) with Pliers

A fast and simple way to clamp sheets together for test fitting, welding, drilling, or riveting.
Clecos offer a fast and reliable way to temporarily hold sheet metal parts together during fabrication processes. This kit includes both types: traditional Cleco pins that fit into drilled holes, and side grip clamps that grip edges where holes aren’t yet practical or needed.

In the world of sheet metal construction, there are countless tools available—some are optional, but Clecos are essential. Whether you're shaping a panel, performing a repair, or building from scratch, the ability to consistently test fit components is crucial. Clecos make this process simple by allowing you to repeatedly position and remove panels with precision.

The included Cleco pins are spring-loaded fasteners that fit into pre-drilled holes, clamping two metal sheets tightly together. They act like temporary rivets, keeping materials aligned while adjustments are made. Use the included Cleco pliers to install and remove them quickly.

The side grip clamps (also called "edge clamps") work in a similar way but are designed to grip the edges of panels without needing holes. They’re ideal for holding seams, flanges, or overlapping joints during prep and fitting. This kit includes both 1″ copper clamps (½″ max opening) and ½″ brass clamps (¾″ max opening) to suit a variety of edge clamping needs.

The included Cleco pliers are used to compress and release both the Cleco pins and the side grip clamps. For Cleco pins, they compress the spring-loaded mechanism so you can insert or remove the fastener from a drilled hole. For side grip clamps, they open the clamp's jaws so you can grip and hold the edges of sheet metal. One tool, two essential functions — making this kit ready to use right out of the box.

Clecos are reusable and come in a variety of sizes, with 1/8" (copper) being the most commonly used in aviation and automotive applications.
