KFS2-440 is a broaching nut designed for mounting on printed circuit boards, featuring an internally threaded M4 x 0.7 metric thread. It is installed by pressing into a non-plated hole, with a minimum hole size of 1.53 mm and a maximum sheet thickness of 1.5 mm. The nut provides a pushout resistance of 680 N in FR-4 fiberglass and a torque-out value of 3.2 N·m when installed under proper conditions. It is compatible with materials including FR-4, aluminum, acrylic, casting, and polycarbonate. The fastener is secured by broaching action, creating a interference-fit with axial grooves on the shank for resistance to rotation. It is supplied in a non-threaded shank configuration for press-fit installation.
