5/16-24 x 1/2 Knurled Point 18-8 Stainless Steel Socket Set Screw identifies a stainless knurled point set screw where the end geometry matters as much as the thread and length.

Cup-point serrations add bite at the contact area, making this style useful for shaft collars, stops, knobs, and adjustment parts that need localized holding contact.

For stainless assemblies, review thread fit and installation practice because stainless-on-stainless contact can raise galling concerns if the joint is assembled dry or repeatedly adjusted.

Use cases for 5/16-24 x 1/2 include instrumentation, equipment panels, and stainless control hardware and shaft collars, hubs, and positioning collars where a headless internal-hex screw keeps the component exterior clear.

For 5/16-24, UNF has 24 threads per inch; check the 1/2 in. length against tapped depth and point location. Check the screw length against the contact location so the point reaches the intended surface without bottoming out. Cold Headers works with socket fastener requirements where small catalog details can affect the final order.
