Cleco Wing Nut (CWNL) Series Fasteners offer the same precise manual control and high clamping force as the standard CWN Series, but with an extended grip range of 0–1". Delivering substantially higher pressure than standard spring Clecos, they’re ideal for low-volume or prototype applications that require strong, adjustable holding power. For high-production environments where speed and consistent clamping are essential, the CHN Series, used with a power nut runner, offers the same performance with improved efficiency. Wing Nut Clecos deliver an adjustable clamping range from 0 to 300 lbs, providing outstanding versatility and control.
