304 Stainless Steel Tamper-Resistant One-Way Round Head Screws
Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. They’re passivated for added protection against oxidation and corrosion. The S-shaped drive can be installed with a standard slotted driver, but requires a special tool for removal (sold separately). For removal tools, see one-way bits and drivers. Length is measured from under the head.
