For drawings calling out 4-40 x 3/16, 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 electronics enclosures, instrumentation, and lab fixtures. The point choice matters as much as thread and length because it controls whether the screw bites, bears, locates, or repositions cleanly on the mating part.
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 helps maintenance teams and industrial buyers locate uncommon socket set screw sizes without adding unsupported inventory claims.
