The TE Connectivity 5205817-2 is a female screwlock kit from the AMPLIMITE HD series, supplied as a 10-piece bag. It includes both a 4-40 jackscrew socket and a 4-40 screw — the hardware that secures the D-sub connector pair against vibration and cable strain. The threaded portion below the head measures 0.312" (7.92 mm), sized for standard D-sub panel thicknesses. This kit is intended for use with AMPLIMITE series HDF and HDP connectors, the high-density D-sub families that require the female screwlock on the receptacle side.
Thread Fit and Panel Clearance
The 4-40 thread is the standard UNC size for D-sub hardware, but the 0.312" below-head length sets the panel thickness limit. If your enclosure wall or mounting bracket is thicker than 0.312", the screw will bottom out before the connector face seats — check the stack-up before committing. The kit provides both the socket and the screw, so you get the mating pair in one bag rather than sourcing them separately.
The product status is Active and RoHS3 compliant.
