The plier-operated (K) series cleco sheet holder clamp is the standard temporary fastener solution. These spring-loaded and steel bodied fasteners are dedicated to light clamping forces (No more than 25lbs.) and are a simple, plier-actuated, inexpensive, alternative to competitive fasteners.
The cleco fastener (sometimes spelled cleko), also known as a skin pin, is a fastener that was originally developed by the Cleveland Pneumatic Tool Company.
Cleco fasteners are widely used in the manufacture and repair of aluminum-skinned aircraft and in automotive repair, where they are used to temporarily fasten multiple sheets of material together before the pieces are permanently joined.
Cleco Pliers
Cleco pliers are specially designed for installing spring-loaded temporary fasteners. A specially designed ''body seat'' holds the fastener in place while the plunger is depressed. These nickel-plated or black-oxide coated pliers are constructed of forged steel, thus resisting wear, abuse, and corrosion.
