Tamper-Resistant Torx Rounded Head Screws for Sheet Metal
A tamper-resistant Torx driver is required for installation and removal. Also known as pin-in-Torx, these screws allow you to apply extra force with less slippage or damage to the recess. Made from 18-8 stainless steel, they are chemical resistant and may be mildly magnetic. They penetrate 0.025" and thinner sheet metal. Length is measured from under the head.
