Jon... yup... "Robertson screwdrivers are easy to use one-handed, since the tapered socket retains the screw, even if it is shaken. They also allow for the use of angled screw drivers and trim head screws. The socket-headed Robertson screws are self-centering, reduce cam out, stop a power tool when set, and can be removed if painted-over or old and rusty. In industry, they speed up production and reduce product damage."

There sould be none other allowed.

McGrath... no way for sure I know of but I hope you make out okay with that annoying problem.
