Glispro – Jack Nut
The Glispro – Jack Nut is a versatile fastening solution designed for soft or thin materials where traditional rivet nuts may not hold effectively. Its collapsible body expands during installation, providing strong grip and load-bearing capability even in oversized or irregular holes.
Engineered for quick and secure installation from one side of the workpiece, the Jack Nut is ideal for applications in sheet metal, plastics, fiberglass, and other low-strength materials. It requires no special tools and can be installed with a standard screwdriver or wrench, making it a reliable choice for field repairs or high-volume assembly.
