About 18-8 Stainless Machine Screws
Grade 18-8 stainless steel (Type 304) provides excellent corrosion resistance in atmospheric, marine, and mild chemical environments. For machine screws, 18-8 is the standard stainless alloy for enclosure and panel fastening where the combination of corrosion resistance and standard thread engagement is required.
Anti-seize is recommended when threading stainless screws into stainless tapped holes — the alloy can gall under torque without lubrication. For saltwater immersion, consider Type 316 stainless (with molybdenum) for additional chloride resistance. Questions about material selection? Contact us.
