For drawings calling out 4-40 x 1 1/4, this 18-8 stainless socket set screw listing covers four point options: Cone, Flat, Oval, and 1/2 Dog. Flat point versions bear without a penetrating tip, making them useful on hardened shafts, machined flats, and assemblies that require periodic readjustment.

Common application reviews include conveyors, packaging machinery, and maintenance repair work. Review shaft material, point contact, drive access, and whether the mating component can accept an indentation before choosing the final point style.

18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material referenced to ASTM F880, used for general atmosphere, moisture exposure, and clean appearance. Cold Headers' socket fastener focus is useful when thread, length, material, and point style need to line up with an existing bill of materials.
