4-40 x 1/4 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 stop collars, sliding mechanisms, and fixture registers; it may also fit gear hubs, linkage arms, and keyed shaft hardware where repeatable register is part of the assembly design. For service work, compare the existing screw, print note, and receiving slot before ordering.

For 4-40 x 1/4, review the listed thread and length first because those catalog values control the exact SKU. The reference values for this nominal size list a ~1/16 in. dog point length. Cold Headers is useful when uncommon lengths or point-style details make an ordinary set screw search unreliable.
