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

A nylon patch bonded to the threads adds friction to prevent loosening from vibration. Made of 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic.

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

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

18-8 stainless steel screws have good chemical resistance.

Stronger and more wear resistant than 18-8 and 316 stainless steel, these screws are mildly chemical resistant.

These square-drive screws are beveled under the head for use in countersunk holes.

Install and remove these screws with a tamper-resistant spanner driver.

Made from 18-8 stainless steel, these screws are chemical resistant.

Made from stainless steel, these screws are more corrosion resistant than steel, and almost as strong.

With a drilling tip, these metric screws cut their own pilot hole and threads as you fasten them into material.

These steel screws cut threads in drilled holes as they’re turned, so they require less driving torque and cause less stress on your material than thread forming screws.

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.

18-8 stainless steel screws have good chemical resistance.

These screws are beveled under the head for use in countersunk holes.

With more points of contact than Phillips-, slotted-, and square-drive screws, you can firmly press these Torx-drive screws into wood without stripping them or damaging the recess—their threads create a tight hold.

Brass screws are corrosion resistant in wet environments and electrically conductive.
