6-40 x 1 Knurled Point Alloy Steel Socket Set Screw supports maintenance replacement work where thread, length, material, and point style must match the existing part.
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 6-40 x 1 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 6-40 thread designation identifies a inch-series inch thread with 40 threads per inch, and the 1 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.
