5/8-18 x 1 1/2 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 5/8-18 x 1 1/2 include tooling details, clamp collars, and positioning hardware; it may also fit machine repairs, replacement assemblies, and point-style controlled maintenance work where a headless set screw keeps the outside of the component clear while point contact provides the holding action.
The 5/8-18 thread designation identifies a UNF inch thread with 18 threads per inch, and the 1 1/2 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 industrial set screw sourcing when the point style is easy to overlook on the print.
