Attach nuts from M3-M6 with pressure. Since nut's hexagonal section is pressed into the workpieces and since the metal sinks into the nut groove, high torque and high anti-pull out resistance can be obtained. Can be put into both the surfaces and backsides of pre-pierced workpieces.

Attach nuts from M8-M12 with pressure. Nut's hexagonal is pressed into workpieces and the metal sinks into the nut's groove. Gives both high torque and high anti-pull out strength. Can be put into both the surfaces and backsides of pre-pierced workpieces.

Can be fully embedded in the back or side of workpiece, so it is suitable for products in which space is limited. Because the nut's hexagonal section is pressed into the workpiece and the metal sinks into the nut groove, high torque and anti-pull out resistance are possible.
