3/8-16 x 1 3/4 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 five-point structure lets the same square-head size serve locating, bearing, and seating requirements. Half Dog points register into shallow holes or slots when location matters under load.
Cold Headers supports square-head set screw sourcing with a catalog organized around exact size, standard, and point selection. Review the selected point, wrench clearance, and mating feature before substitution. For cup point square heads, use the separate Cup Point Square Head Set Screws category rather than this five-point family.
