Cleco fasteners are used to temporarily fasten steel and aluminum panels before they are permanently drilled or riveted. They have a cylindrical body, top plunger, spring, two step-cut locks and spreader bar.
Standard button plungers have a spring-loaded body. They are used with pliers in precision applications.
Used 7 on heavily oxidized Airstream. Sanded off oxidation. Presto changeo, an almost mirror-like finish. Will stick with Nuvite. Important to follow instructional video.
This is an amazing aid to my fisning. Something serious inland fishermen should have. My only regret is that I didn't have this over the last 20 years.
