These metric brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic.

Made from alloy steel, these screws are twice as strong as standard steel Torx flat head screws.

A286 stainless steel screws have comparable strength to alloy steel with the corrosion resistance of 18-8 stainless steel.

Made from alloy steel, these screws are nearly twice as strong as stainless steel flat head screws.

With a tamper-resistant Torx or Torx Plus drive (also known as a pin-in Torx or Torx Plus drive), these screws are difficult to remove without special tools.

With an O-ring under the head, these metric screws seal out leaks and contaminants while also preventing unwanted removal.

With a tamper-resistant hex drive (also known as a pin-in hex drive), these metric screws are difficult to remove without special tools.

These screws are drilled through the shaft to vent fluids and gases trapped under the screw.

Tighten these metric screws by turning them to the left; once fastened, they prevent loosening from counterclockwise motion.
