That makes it straightforward for projects requiring M4 fasteners, but less suitable if you need multiple thread sizes.

These fasteners use a flower-shaped or petal expansion structure. During installation, the petals are designed to spread behind the mounting surface, helping secure the nut in thin material. This design is presented for thin panel installation, including sheet metal and equipment panels, where conventional fastening options may be unsuitable.
