It carries a 4-40 thread and a threaded portion below the head measuring 0.216\" (5.49 mm), with a slotted drive for hand or tool tightening. This is the screw that secures the latch lock to the D-sub shell — not a connector body, but the mechanical fastener that keeps the mated pair from backing off under vibration. ## Thread Fit and Mechanical Compatibility The 4-40 thread is the standard UNC size for D-sub hardware — the same thread used on the jackscrews of standard-density DB connectors. The 0.216\" length below head matches the typical panel thickness and latch lock clearance in a standard D-sub shell. If you are replacing a missing or stripped jackscrew on a D-sub latch lock assembly, this is the direct fit for the Molex F-SGK / FCT series latch locks.","metaTitle":"Molex 1731120405 D-Sub Latch Lock Screw, 4-40 Thread","metaDescription":"Molex 1731120405 jackscrew for D-sub latch lock, 4-40 thread, 0.216\" length below head.
