This 4-40 x 5/8 18-8 stainless socket set screw is a size-specific listing for Cone, Flat, Oval, and 1/2 Dog point selections in mechanical assemblies. Oval point versions use a radiused tip that contacts at a tangent, which can suit curved seating surfaces, splines, grooves, and repeat positioning work.
Common application reviews include control handles, adjustment screws, and replacement assemblies. Because 18-8 stainless is not heat treated, holding torque is below alloy steel; compare alloy socket 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, used for general atmosphere, moisture exposure, and clean appearance. Cold Headers has supplied specialty socket fasteners since 1962 and supports exact-size sourcing for hard-to-find socket products.
