Install nuts on thin or unweldable workpieces with pressure
KALEI Nuts

Joints are strong because the knurl anchors workpieces after attachment.Cross section of KALEI Nut Kalei Nuts can be installed not only in steel, but also aluminum and stainless steel unsuitable for welding.

Provides high torque & anti-pull out resistance because of press nuts' hexagonal section
ST Nuts

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.Cross section of ST Nuts Can be put into both the surfaces and backsides of pre-pierced workpieces.

Press nut's hexagonal section provides high torque & anti-pull out resistance
SG Nuts

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.Cross section of SG Nuts Can be put into both the surfaces and backsides of pre-pierced workpieces.

Spacers can be pressed from the surface
POP Spacers

Spacers for attaching to metal pieces from the surface as a spacer for printed circuit boards. Because of POP's original shape, high strength can be obtained.

Provide high anti-pull out resistance because they are inserted from the back
Through Spacers

Have high anti-pull resistance because they are attached to metal workpieces from the backside with flange part. Spacer height is from 4.0mm to 12.0mm by 1.0mm and 14.0mm is also available.

Fully embeds in both surface or backside of the workpiece
Flat Nuts

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.
