3-48 x 3/8 Knurled Point Alloy Steel Socket Set Screw is selected when cyclic loading, access limits, and point geometry all matter to the assembly review.
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 3-48 x 3/8 include conveyor hardware, packaging machinery, and compact mechanical controls; it may also fit handles, couplings, stops, and light indexing components where a headless set screw keeps the outside of the component clear while point contact provides the holding action.
The 3-48 thread designation identifies a UNC inch thread with 48 threads per inch, and the 3/8 in. length should be checked against tapped depth, contact location, and drive access.
For replacement work, match the point style before comparing only diameter and length. Cold Headers focuses on specialty socket products where item-level details matter to the final order.
