6-40 x 3/16 Knurled Point Alloy Steel Socket Set Screw is a headless set screw for shafts, hubs, and stops where the knurled cup point provides localized 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 6-40 x 3/16 include machine repairs, replacement assemblies, and point-style controlled maintenance work; it may also fit fixtures, stops, and removable parts that still need a positive point bite 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 3/16 in. length should be checked against tapped depth, contact location, and drive access.
This style should be reviewed against shaft material, access, adjustment frequency, and the amount of surface marking the assembly can tolerate. Cold Headers helps buyers keep specialty point geometry, exact size, and material together during quoting.
