1/2-13 x 2 3/4 Knurled Point Alloy Steel Socket Set Screw gives machine builders a headless internal hex fastener for set positions that need knurled point engagement.
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 1/2-13 x 2 3/4 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 1/2-13 thread designation identifies a UNC inch thread with 13 threads per inch, and the 2 3/4 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.
