Alloy Steel Button Head Torx Screws
Made from alloy steel, these screws are three times stronger than standard steel button head Torx screws. A Torx-Plus drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess. For Torx tools, see Torx and Torx-Plus bits, keys, and drivers. Torx-Plus screws can be used with both Torx-Plus and Torx tools. Length is measured from under the head.
Black-oxide alloy steel screws are mildly corrosion resistant in dry environments.

Alloy Steel Torx Flat Head Screws
Made from alloy steel, these screws are twice as strong as standard steel Torx flat head screws. A Torx-Plus drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess. For Torx tools, see Torx and Torx-Plus bits, keys, and drivers. These screws can be used with both Torx-Plus and Torx tools. They’re angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.
