Metric Steel Torx Flat Head Screws
Zinc Plated
Torx
These screws are twice as strong as standard steel Torx flat head screws. A Torx or 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. They’re angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.
Zinc-plated steel screws have a layer of zinc that protects the steel underneath from rusting in wet environments.

Metric 18-8 Stainless Steel Torx Flat Head Screws
Torx Drive
These 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. Screws are passivated for added protection against oxidation and corrosion. Torx and Torx-Plus drives have 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 . Screws are angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.
