1/2-13 x 5 is a UNC square head set screw for applications where the installed head can project and the point is chosen separately.
Typical applications include dirty work areas where an external square head remains serviceable when recesses collect debris. The row represents a square-head size, while the point selection is made from Half Dog, Full Dog, Cone, Oval, and Flat. External wrench access is useful when an internal socket recess would be hard to keep clear.
Cold Headers brings long socket and set screw experience to older machine platforms where square-head hardware is still specified. Review the selected point, wrench clearance, and mating feature before substitution. Socket set screw families provide the internal-drive alternative where square-head projection or wrench swing will not clear.
