    They are: G9409145 (3/8" -24 X 1/2") 6 Required. You could not find these anywhere now, unless a few are at some Studebaker Vendors.

    Can you post some pictures? They do sound like place head screws.

      Yes those are place head or place screws. The head design provides more elasticity making it act like a longer bolt. This provides better resistance to loosening. They are considered self locking. They are available comercially. I have used them in military applications where we were trying to avoide loosening in critical applications. This is a grade 8 screw.

        Good to know David, a "Place Head Screw". Maybe Auveco or one of those Fastener Co's actually still has those.

        Used where vibration is an issue, I immediately thought of Helicopter Parts.
