3-48 x 1/4 Knurled Point Alloy Steel Socket Set Screw gives purchasing teams a precise catalog line for an alloy steel knurled point set screw.

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 3-48 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 3-48 thread designation identifies a UNC inch thread with 48 threads per inch, and the 1/4 in. length should be checked against tapped depth, contact location, and drive access.

Review the mating material, surface condition, and allowable witness mark before substituting a different point style. Cold Headers supports socket fastener sourcing where point geometry affects fit.
