4-40 x 1 1/2 18-8 Stainless Steel Socket Set Screw is intended for headless fastening where drive access is through the socket and point style determines the seating action. 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 instrument housings, lab fixtures, and moisture-exposed equipment. A flat point can protect a hardened or finished seating surface better than a cone point, while an oval point can help where the seating surface is rounded or angled.
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. When standard catalog searches are too broad, Cold Headers supports precise socket set screw sourcing by size and point-style requirement.
