Cleco Sheet Metal Fasteners with Installation Pliers – 3/16inch, 20 clecos

Cleco fasteners are cylindrical, spring-enclosed fasteners that are designed to temporarily hold parts together. They were originally developed for manufacture and repair of aluminum-skinned aircraft. These extremely handy and versatile fasteners come in an assortment of shapes and sizes and are used to temporarily fasten sheets of material together, or to hold parts such as stiffeners, frames etc. together, before they are permanently joined.

Clecos are installed in holes drilled through the workpieces (usually holes intended for permanent fasteners installed later). By drilling holes at strategic locations on the parts in your assembly, you can insert cleco fasteners to hold the parts together in perfect alignment until they are permanently joined, saving you valuable time and money. Clecos provide the ultimate peace of mind and assurance that none of your parts will move during joining and that even the tightest tolerances can be maintained. No other hardware option ensures such tight tolerances and ease of assembly.

Hand operated cleco fasteners, used throughout the aviation industry, consist of spring or plier operated, bar nut and wing nut styles and their installation requires Cleco Pliers. Power operated clecos include hex nut, cylindrical body or round body types. Most cleco clamps are available in various lengths and strengths to accommodate various manufacturing processes.
