1/2-20 x 3/4 Knurled Point Alloy Steel Socket Set Screw keeps the knurled point callout visible when a generic socket set screw search would be too broad.
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 1/2-20 x 3/4 include industrial equipment where the screw installs flush within the tapped component; it may also fit automation equipment, fixture blocks, and serviceable machine covers where a headless set screw keeps the outside of the component clear while point contact provides the holding action.
The 1/2-20 thread designation identifies a UNF inch thread with 20 threads per inch, and the 3/4 in. length should be checked against tapped depth, contact location, and drive access.
The knurled point can be useful where a plain cup point has a tendency to work loose under repeated motion, but final fit still depends on the assembly. Cold Headers supports socket fastener sourcing where point geometry affects fit.
