For line-shaft hardware, collars, and similar mechanical locations, 3/4-10 x 2 gives buyers the square-head set screw style named on many older drawings.

Typical applications include older machine tools that were designed around wrench-driven set screws. The row represents a square-head size, while the point selection is made from Half Dog, Full Dog, Cone, Oval, and Flat. Point selection should reflect the shaft feature, acceptable marking, and expected service adjustment.

Since 1962, Cold Headers has helped industrial buyers identify specialty set screws by thread, length, head style, and point requirement. Review the selected point, wrench clearance, and mating feature before substitution. Oval points suit grooves or repeated adjustment where a radiused contact is useful.
