No, in the case of the speaker, two conventional round head bolts are used which have a "square" for lack of a better term under the rounded head. This "square" locks into the holes in the mounting ears of the U-28 speaker used in the 38-1. A washer and nut are attached to each bolt, on top of the speaker mounting board.
