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

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

To prevent leaks and seal out contaminants, these metric screws have an O-ring under the head.

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.

18-8 stainless steel screws have good chemical resistance.

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

Beveled under the head for use in countersunk holes, these steel screws press threads into material for a tight, secure hold.

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.
