JACKRIV-Rivet nut Steel h.10,0 gr0,4-4,8 DH M5/C/L=18

Steel.
Dome head.
Jackriv rivet nuts allow female threads to be made on thin and soft materials to accommodate metric screws with pitch M4-M5-M6-M8.
For each rivet nuts size, two different heights are available depending on the thickness of which Jackriv is used.
One of the most interesting features of these rivet nuts is having large bearing surfaces on both sides of the assembly, wide head on one side and expansion of the four-part star-shaped material on the opposite side.
This provides a secure anchorage, especially on those materials where there are difficulties with bracketing: plywood, fiberglass, plastic, plexiglass.
