Standard hex nut cleco fasteners. The Hex Nut (KH) series is operated with a pneumatic power tool and best suited to high-production settings requiring fast, consistent, uniform clamping force. Its 'free-wheeling' design allows it to back completely off while still remaining intact with the body. This fastener is suitable for all types of metallic and composite materials.
Clecos, or skin pins as they are sometimes called, have played an important role in automotive, racing and aircraft sheet metal repair for decades.
