KFB3™ broach/flare-mount standoffs are designed for enhanced pullout performance in printed circuit boards, combining a broached shank with a flared base to secure the fastener in non-plated holes. The part number KFB3-440-8ET corresponds to a #4-40 thread size with a length code of 8 (equivalent to 0.250 inches), and is rated for a maximum sheet thickness of 0.065 inches, with a minimum hole-to-edge distance of 0.09 inches. The standoff features a threaded length of 0.219 inches and an overall height of 0.250 inches, with a head diameter of 0.335 inches and a bore diameter of 0.179 inches for screw clearance. It is intended for installation in PCB materials and compatible substrates such as aluminum, acrylic, casting, and polycarbonate. The design ensures a permanent, rotation-resistant fit without requiring additional hardware.
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.
