Mounting hardware: The mounting hardware shall allow mounting the socket above, or below the panel
or chassis, and shall allow mounting and securing the relay to the socket without distributing the
mounted socket or access to the wiring side of the socket (see figures 3 and 4). The hardware shall
provide the nominal spacing between socket surface and relay mounting flange, regardless of the
mounting configuration.
Supplied with relay socket:
8 each .112-40 self locking nuts (.206 max dia x .176 max height).
8 each .112 flat washers (.220 max O.D. x .018 max thick).
4 each .190-32 self locking nuts (.330 max dia. X .190 max height).
4 each .190 flat washers (.360 max O.D. X .036 max thick).
4 each studs for loose mounting configuration only (see figure 4).
Fixed mounting studs: Studs shall be fixed into the mounting flange of the socket and shall be designed
so as to prevent rotation of the stud within the flange (see figure 3).
Contact installation tools: See table III.

Torque: Relay socket and hardware shall be subjected to torque testing as specified in table IV.
Sockets shall be installed in mounting panel when test torque is applied. No visual evidence of physical
damage shall be permitted. Torque shall be maintained for a reasonable period of time to insure stud,
socket, and associated hardware have not been damaged (see table IV).
