BLIND NUT™ System.
Description.
The BLIND NUT™ fastener is a simple and robust solution to provide a thread. Its installation is suitable instead of conventional nut plates where a closed structure does not allow access from the back or where the fatigue criticality of the sub-structure in fatigue does not allow holes to be drilled for the installation of conventional nut plates.
Features.
- High strength threaded expander with a choice of sleeve in multiple materials and shapes
- Ideal replacement or repair of nearly any existing structural panel fastener
Tools.
Technical support and hydraulic tooling solutions to install the BLIND NUT™ fasteners onto the sub-structure are also provided by LISI AEROSPACE.
Licensed manufacturers.
BLIND NUT™ nuts are only manufactured by authorized, licensed manufacturers. To ensure you are buying only the highest quality products, see our official list of licensees here:
