18-8 stainless steel button head screws have good chemical resistance and may be mildly magnetic.
Made from 18-8 stainless steel, these metric screws have good chemical resistance and may be mildly magnetic. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.
18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange distributes pressure across a wide surface, eliminating the need for a separate washer.
These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.
