4-40 x 1 18-8 Stainless Steel Socket Set Screw is an internal-hex headless fastener supplied in Cone, Flat, Oval, and 1/2 Dog point styles. Cone point versions use a cone tip that can indent the mating shaft for strong axial holding in fixed settings, especially when a prepared dimple is part of the design.
Common application reviews include clean-looking equipment panels, small mechanisms, and production tooling. Slight magnetism can occur from cold working in 18-8 stainless, which is normal for this austenitic stainless family and should be considered where magnetic response matters.
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. For production, repair, and distributor sourcing, Cold Headers can help confirm the exact size and point-style family before quoting.
