mounting configuration, (see figures 2 and 3).
Supplied with relay socket:
4 each .112-40 self locking nuts (.206 max dia x .176 max height).
4 each .112 flat washers (.220 max O.D. x .018 max thick).
2 each .190-32 self locking nuts (.330 max dia x .190 max height).
2 each .190 flat washers (.360 max O.D. x .036 max height).
2 each studs for loose mounting configuration only (see figure 2).
Fixed mounting studs: Studs shall be molded into the mounting flange of the socket and shall be
designated so as to prevent rotation of the stud within the flange (see figure 3).
