The K3S50-1 Set of 25 1/8” & 25 3/16” Standard Cleco Fasteners w/ Mesh Carry Bag comes with a durable, polyester zippered carry bag (6” H x 8.5” W). 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.
