4-40 x 1 3/4 Alloy Steel Socket Head Cap Screw gives engineers an internal-hex fastener for mechanical joints where socket engagement and dimensional consistency matter. With a 4-40 thread and 1 3/4 in. length, it fits socket-drive service locations where size interchangeability matters. Industrial buyers may specify it for machine tools, automation systems, and fixture design where head geometry and drive access need to be predictable.
