Screws are beveled under the head for use in countersunk holes.

18-8 stainless steel screws have good chemical resistance.

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

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

These steel screws are zinc plated to resist corrosion in wet environments.

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.

These steel screws are zinc plated to resist corrosion in wet environments.

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

These screws cut threads into drilled holes as they’re turned, so they require less driving torque and cause less stress on material than thread-forming screws. Made of steel, they have an ultra-corrosion-resistant coating to resist corrosion in wet environments.

Thread-forming screws press threads into drilled holes for a tight, vibration-resistant assembly.

The neoprene-backed washer seals out contaminants.

Install these thumb-screw-head screws through a hole and thread on a retainer to keep secure—no special tools are required.

Install in soft material such as aluminum and low-carbon steel at least 0.036" thick with an arbor press or similar pressure tool.

The base flares out during installation, creating a backside flange in hard materials and near edges in panels up to 0.312" thick. Install with a flare-in installation tool and an arbor press.

Press these wing head nuts into a closed-end hole or thick panel in applications where the back of the panel is inaccessible. A quarter-turn locks and releases access panels, doors, and covers.

Press these rounded head nuts into the backside of a panel in applications where you have access to both sides of the panel. A quarter-turn locks and releases access panels, doors, and covers.

These wing-head screws have a clip-on nut that allows you to mount them near the edge of a thin panel. Use them to lock and release access panels, doors, and covers with a quarter-turn.

These rounded head nuts can be riveted into thin panels for a flush fit. They can be mounted without spaces between the panels. A quarter-turn locks and releases access panels, doors, and covers.

These rounded head screws have a nut that clips onto the edge of a thin panel, allowing you to mount the screw near edges. A quarter-turn locks and releases access panels, doors, and covers.
