When a threaded component must be seated with external wrench access, 7/16-14 x 3 provides the traditional square head set screw format.

Typical applications include construction machinery where large wrench flats are easier to clean and grip. The product record carries the size; the requested point is selected from the Half Dog, Full Dog, Cone, Oval, and Flat menu. Point selection should reflect the shaft feature, acceptable marking, and expected service adjustment.

Availability-row diameters and unusually long lengths are handled as quote-driven square-head requirements by Cold Headers. Review the selected point, wrench clearance, and mating feature before substitution. Cup Point Slotted Headless Set Screws are the related headless option when flush-fitting screwdriver access is preferred.
