Use the 5-40 x 1 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 shaft collars, knobs, and machine controls. For replacement work, match the existing drawing callout before changing point style; the same diameter and length can behave differently with cone, flat, oval, or 1/2 dog contact.
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.
