4-48 x 5/16 Knurled Point Alloy Steel Socket Set Screw suits serviceable equipment where a plain cup point may be less desirable under repeated motion.

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 4-48 x 5/16 include repair bins, equipment rebuilds, and exact-size set screw substitutions; it may also fit tooling details, clamp collars, and positioning hardware where a headless set screw keeps the outside of the component clear while point contact provides the holding action.

The 4-48 thread designation identifies a inch-series inch thread with 48 threads per inch, and the 5/16 in. length should be checked against tapped depth, contact location, and drive access.

The knurled cup point is usually chosen for localized bite rather than for a locating-hole function. Cold Headers helps buyers keep specialty point geometry, exact size, and material together during quoting.
