1-8 is a size-level square head set screw entry for quote-driven ordering across standard lengths and specified point styles.

Typical applications include legacy equipment repairs that need the square-head form called out on older drawings. The row represents a square-head size, while the point selection is made from Half Dog, Full Dog, Cone, Oval, and Flat. Flat points bear against a machined flat without intentional penetration into the mating surface.

Cold Headers can review less-common square-head sizes, long lengths, and point combinations when the standard catalog matrix does not cover the need. The family runs UNC coarse thread throughout, the traditional square-head series. When the assembly cannot accept an exposed square head, compare headless socket set screw families before substituting.
