M6 304 Stainless Steel Tamper-Resistant Button Head Torx Screws
Made from 18-8 stainless steel, these button head screws have good chemical resistance and may be mildly magnetic.They’re passivated for added protection against oxidation and corrosion. The tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools. For installation tools, see tamper-resistant Torx drivers and bits. Length is measured from under the head.
