KFB3™ broach/flare-mount standoffs are threaded fasteners designed for secure attachment to PC boards, combining broaching and flaring features to enhance pullout performance. The M4 x 0.7 thread size has a shank length of 12 (3.81 mm), a maximum sheet thickness of 1.65 mm, and minimum hole diameters of 1.27 mm in the PCB and 1 mm in the mating sheet. Thread length is full, with a minimum of 9.5 mm from the head end. The fastener dimensions include a head diameter of 6.68 mm, a body diameter of 5.23 mm, and a center-to-edge clearance of 6.36 mm. It is intended for use in non-plated holes in PCB materials and compatible substrates such as aluminum or polycarbonate.
No matter how sophisticated or advanced, electronic components must be attached reliably and securely if they are to deliver optimum performance. We offer several fastener products for use with PC boards to satisfy component-to-board, board-to-board, and board-to-chassis attachment needs.
Broach/flare-mount standoffs offer greater pullout performance.
