If you sometimes have to wiggle the board around, that would indicate that the connector (the board mount receptacle) isn't the greatest. You could solder them in and that should be much more reliable. If you really want them to be removable, one thing I have used (for 7 pin dual FETs and for transistors) are pin receptacles from Mill-Max. Note that you would need to mic the pins on the board, and order the appropriate size of these. You most likely would also have to enlarge the holes in the board (PCB drill), which if it is a single sided board, or if all connections (traces) are on the bottom of the board is not that big of deal (with a drill press).
