5/16-18 x 3/8 Knurled Point Alloy Steel Socket Set Screw provides a size-specific alloy steel option for designs that rely on knurled cup point contact.
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 5/16-18 x 3/8 include production machinery that uses internal hex set screws to avoid external head clearance; it may also fit shaft collars, control knobs, and hub-mounted components where a headless set screw keeps the outside of the component clear while point contact provides the holding action.
The 5/16-18 thread designation identifies a UNC inch thread with 18 threads per inch, and the 3/8 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 focuses on specialty socket products where item-level details matter to the final order.
