KF2 and KFS2 broaching-type fasteners are designed for use on printed circuit boards and on most brittle or hard materials; such as glass laminates, epoxy or resin with paper, nylon, or canvas bases, carbon fiber plate. They are also used on thin or unsuitable materials for threading, such as acrylic and polycarbonate panels. Once installed they provide a strong permanent thread in any printed circuit board material. 

Thread sizes #2 to #10 and M2 to M5. KF2 and KFS2 fasteners are simply pressed into the prepared hole.
