Jack nuts/Petal nuts are blind fasteners designed for assembly line use in thin, soft, or brittle materials.When tightened, the body collapses to form four legs which grip the inside of the mounting surface, leaving a permanent, reusable threaded insert.

1. Fasten in blind holes
2. Won't distort materials
