Cleco Fasteners feature a steel body construction and spring-loaded plunger, and are a simple, inexpensive alternative to competitive fasteners. Able to apply up to 25 pounds of force per fastener, Clecos are easily operated by using the specially designed Cleco Pliers. A specially designed ''body seat'' holds the fastener in place while the plunger is depressed.

To use Cleco Fasteners, simply place the fastener in the pliers, and squeeze the plier handle to sink the plunger and extend the pins, otherwise known as step-cut locks. Once the desired holes have been lined up, thread the Cleco through the holes and release plier grip. This causes the step-cut locks to retract and expand back towards the steel body, which secures the panels together. Cleco Fasteners can be just as easily removed by following the same steps.

Before Clecos, workers had to fasten panels together using nuts and bolts, which often required two people – one on each side of the panel – to properly hold everything in place. Clecos are blind fasteners, in that the tool can be used even when the worker does not have access to the other side, granting far greater versatility and usability than other panel fastening fabrication methods.

MRO TOOLS KSG Series Side-Grip Clamps are plier-operated and designed to clamp material together where no holes are available. MRO KSG Series Side-Grip Clamps are ideal for bonding and sealant operations, but work perfectly with all types of materials. MRO KSG Series Side-Grip Clamps feature a larger surface area that minimizes scarring while its spring-loaded mechanism prevents over-tightening.
