Hex Steel Rivet Nut Inserts are used in conjunction with a hexagon hole. Therefore, maximum resistance to applied torque or unscrewing torque is achieved. They are available in large flange as well as thin flange.
Flanged head Rivstuds are designed for use in hard metric dimensioned drilled or punched holes. They feature a rivnut body with a stud and can be used as an alternative to weld-studs or clinch-studs. Available from M4 to M8 from RivetLab®.
