A device for securing passenger seat frame structures (e.g., seat spreaders, legs) to a lateral crossbeam (130) includes a wedged clamping device (204) insertable into a pocket (308) directly adjacent to a passage allowing the crossbeam to pass through the seat frame structure. The wedged clamping device has an upper face providing a locking taper angle and a lower arcuate face opposite the upper face and in contact with the crossbeam. When inserted into the pocket, the wedged clamping device provides a clamping force securing the seat frame structure to the crossbeam without driving a bolt through, deforming, or otherwise compromising the integrity of the crossbeam. The wedged clamping device accepts a tuning bolt through a lateral face; tightening the tuning bolt can more precisely control the amount of clamping force provided on the crossbeam.
