The TE Connectivity 5554858-1 is a jackscrew socket accessory from the CHAMP series, designed as a standoff screw for CHAMP D-Sub shielded vertical mount PCB connectors. It carries an M3.5 Socket thread on one end and a 6-32 Screw thread on the other, with a slotted drive for tool engagement. This is the hardware that secures the connector to the panel or board and provides the mechanical retention the signal pins alone cannot handle — without it, the mated pair drifts under cable strain and the contact interface opens.
Thread Size and Compatibility
The thread combination — M3.5 Socket and 6-32 Screw — is the fit parameter that decides which CHAMP connector bodies this jackscrew mates with. The M3.5 socket side threads into the connector's standoff boss; the 6-32 screw side passes through the panel or PCB and accepts a nut or threads into a mating bracket. This dual-thread design is standard on CHAMP D-Sub shielded vertical mount PCB connectors, so the 5554858-1 is the correct jackscrew for that family.
