For replacement work on older equipment, 1/4-20 x 2 keeps the UNC pitch patch, length, and square-head drive clear in the product record.

Typical applications include farm implements, mill equipment, and production machinery that need wrench clearance. The product record carries the size; the requested point is selected from the Half Dog, Full Dog, Cone, Oval, and Flat menu. Flat points bear against a machined flat without intentional penetration into the mating surface.

Cold Headers brings long socket and set screw experience to older machine platforms where square-head hardware is still specified. The family runs UNC coarse thread throughout, the traditional square-head series. Socket set screw families provide the internal-drive alternative where square-head projection or wrench swing will not clear.
