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

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. They may be mildly magnetic.

Closely spaced threads on these screws fit in holes with a fine pitch. They're not compatible with standard metric threads.

Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

These metric screws are twice as strong as standard steel Torx flat head screws.

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

Lower strength than alloy steel, use these screws for light duty fastening.

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

Stainless steel screws have excellent corrosion resistance in most environments.

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.

To vent fluids and gases trapped under the screw, these metric screws are drilled through the shaft.

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