Tamper-Resistant Rounded Head Drilling Screws for 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. They save you time and effort by drilling their own holes and fastening in a single operation. Made from 410 stainless steel, they're strong, wear resistant, and mildly chemical resistant. Not for use with aluminum. Length is measured from under the head.

Tamper-Resistant Flat Head Drilling Screws for 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. All are beveled under the head for use in countersunk holes. They save you time and effort by drilling their own holes and fastening in a single operation. Made from steel, they have a zinc plating to resist corrosion in wet environments. Length is measured from the top of the head.
