5-40 x 7/8 Full Dog Point Alloy Steel Socket Set Screw is selected when the screw point is meant to register in a mating feature rather than bite into a plain shaft. The extended cylindrical point is used as a locating element, so the mating component must provide the corresponding seat or slot.
Typical applications include couplings, collars, and parts that must return to the same position; it may also fit tooling plates, locating stops, and serviceable mechanical fixtures where repeatable register is part of the assembly design. Review the hub, shaft, or fixture detail before replacing it with a cup or flat point style.
For 5-40 x 7/8, review the listed thread and length first because those catalog values control the exact SKU. Cold Headers is useful when uncommon lengths or point-style details make an ordinary set screw search unreliable.
