A screw is captured in an assembly of concentric sleeves, the inner one of which has a flange, and an outer workpiece is clamped between the flange and the outer sleeve. The outer workpiece has a sufficiently large, beveled bore to permit radial play of the assembly. The outer sleeve has a threaded inner flange at the other end; and the two sleeves are assembled in press fit.

Screw capture

The two-part nut has a socket member and a member with an internally threaded shank and a flange which is received in a transverse groove in the socket member having a central bore traversed by the shank. The shank has a groove adjacent the flange into which reach upset portions of the socket member to hold the members together with play. The socket member has alternate bores for riveting.
