1/4-28 x 1/4 Knurled Point Alloy Steel Socket Set Screw provides a size-specific alloy steel option for designs that rely on knurled cup point contact.
The serrated knurled cup point bites the mating surface and helps resist vibration-driven back-out in blind holes, softer materials, collars, hubs, and adjustment locations.
Typical review points for 1/4-28 x 1/4 include gears, pulleys, sprockets, and adjustable stops; it may also fit hub retention, shaft-mounted accessories, and threaded adjustment locations where a headless set screw keeps the outside of the component clear while point contact provides the holding action.
The 1/4-28 thread designation identifies a UNF inch thread with 28 threads per inch, and the 1/4 in. length should be checked against tapped depth, contact location, and drive access.
The internal hex drive supports compact installation where side clearance for an external wrench is limited. Cold Headers supports socket fastener sourcing where point geometry affects fit.
