Broach/Flare-Mount Standoffs – Type KFB3

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.
