Use the 5/16-18 x 1/2 18-8 stainless socket set screw size when a bill of materials requires one thread and length with selectable Cone, Flat, Oval, or 1/2 Dog points. 1/2 dog point versions use a short cylindrical tip that locates in a drilled hole or slot for fixed positioning where a pin-like set screw point is specified.

Common application reviews include pump accessories, collars, and rotating-component retention. A 1/2 dog point is useful when the assembly already includes a locating hole or slot, while cone point versions are often selected for fixed settings on unhardened shafts.

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.
