Clecos are temporary, reusable fasteners that are ideal for use on sheet metal, fiberglass, Lexan, and many other fabrication projects. The special pliers are used to install & remove the Clecos. These fasteners are added as mounting holes are drilled & allow easy disassembly for trimming, deburring & removal of the metal chips. During final assembly, the Clecos are removed one at a time, and replaced with rivets. Available in 1/8 in. and 3/16 in. diameters - for use with 1/8 in. and 3/16 in. rivets. Grip Range - up to 1/4 in.
