Specify 4-40 x 3/4 Full Dog Point 18-8 Stainless Steel Socket Set Screw for headless fastening where the unthreaded pilot tip performs the locating work. The pilot end locates the part rather than biting or indenting the mating surface.

Common application reviews include control handles, collars, and removable shaft-mounted components. Because 18-8 stainless is not heat treated, compare alloy steel dog point set screws when maximum seating torque governs the application.

18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material referenced to ASTM F880 for general plant environments, moisture exposure, and clean appearance. Cold Headers helps buyers match uncommon stainless socket set screw sizes to existing drawings and maintenance records.
