2-56 x 1/4 Alloy Steel Socket Head Cap Screw gives engineers an internal-hex fastener for mechanical joints where socket engagement and dimensional consistency matter. This size keeps the specified 2-56 thread and 1/4 in. length visible for bill-of-material consistency. Selected for tooling, assembly equipment, and power transmission, it gives maintenance teams a searchable alloy steel socket screw callout. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. This keeps the listing focused on the fastener geometry rather than broad catalog language.
