    Pentagon Head Screws

    Image of Product. Front orientation. 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.

    Pentagon Bits

    Image of Product. Front orientation. Screwdriver Bits. Pentagon Bits.
    These unique five-point bits turn pentagon screws. Use them to access manhole covers, valve boxes, and other types of public infrastructure.
    Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included).
    Steel—Best for dry environments, since moisture will cause these bits to rust.
