1. amper-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.

2. 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 time and effort by drilling their own jams 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.

3. Strip-Resistant Drilling Screws for Metal. Serrations under the head act as a brake to prevent overtightening and damaging threads. The flange reduces the risk of crushing thin metal. They save you time and effort by drilling their own holes and fastening in a single operation. A hex head provides a larger gripping area for installation with a wrench or socket driver. Length is measured from under the flange. Head height includes the flange. External Hex/Torx drive screws give you a choice to install with a wrench or a Torx driver. Zinc-plated steel screws resist corrosion in wet environments.

4. Torx Drilling Screws for Joining Wood to Metal. A Torx drive has more points of contact than a Phillips drive, allowing you to apply extra force with less slippage or damage to the recess—these screws speed installation by drilling, tapping, and fastening wood and metal in a single operation. Made from zinc-plated steel, they resist corrosion in wet environments. Length is measured from the top of the head.
