Pentagon Head Screws
 |
The five-sided head provides tamper resistance by making these screws difficult to remove without special tools. Install or remove with 5-point sockets (sold separately). Also known as penta-bolts and 5-point screws, they are commonly used on water and gas valves. They are made from 18-8 stainless steel, which has good chemical resistance and may be mildly magnetic. Length is measured from under the head.
