Description

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 such as test fitting, welding, drilling, and riveting.

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.

A Cleco is a spring-loaded fastener that fits into a pre-drilled hole, clamping two metal sheets tightly together. It acts like a temporary rivet, holding the material in place while adjustments are made. As you refine your fit, simply remove and reinsert the Cleco to maintain alignment. These fasteners are installed and removed using a dedicated pair of Cleco pliers-handy tools that you'll find yourself using frequently.

Clecos are reusable and come in a variety of sizes, with 1/8" (copper) being the most commonly used in aviation and automotive applications. Here's a quick guide to the common colour codes:

How to use

Cleco Fasteners

Position the panels. Place one panel over the other in the desired position where you want to join them.
Drill the hole. At each fastening point, drill through both panels using a drill bit that matches the cleco size you plan on using: (3/32″, 1/8″, 5/32″, or 3/16″).
Load the cleco into pliers. Squeeze the Cleco pliers to compress a cleco fastener.
Insert the cleco. While holding the pliers compressed, insert the cleco into the drilled hole, then release the pliers so the fastener locks in place.
Repeat along the joint. Continue drilling and inserting clecos at the required spacing until the panels are secured.
Remove when finished. To remove, use the pliers to compress the cleco and pull it out of the hole.

Cleco Clamps

Align the panels. Place the panels edge-to-edge in the position you want to hold them together.
Load the clamp into pliers. Squeeze the Cleco pliers to compress a side grip clamp.
Attach the clamp. Position the clamp so the jaws grip across both panel edges, then release the pliers so the clamp grips tightly.
Remove when finished. To remove, use the pliers to compress the clamp and lift it off the panels.
