Black & Decker Iron Model is F362WH

Sole plate is loose at rear so I'm trying to open iron to tighten it.

Tri-Wing security screw at rear is doing its job and keeping me out of the iron.

I suspect the Tri-Wing needs a #3 or a #4 size bit, does anyone know the actual size?

I bought a set [6] Wiha Tri-Wing bits from Amazon [#0 thru #6] for $15. The #3 was an exact fit.

That's the good news, I removed the screw but can't get the back off the iron, so it's an empty victory.
