Steel Hex Head Drilling Screws for Metal
These steel screws have corrosion-resistant finishes. A hex head provides a secure grip with a wrench and a flange reduces the risk of crushing thin metal. They save you time and effort by drilling their own holes and fastening in a single operation. Length is measured from under the flange. Head height includes the flange.
Zinc-plated steel screws resist corrosion in wet environments.

Drilling Screws for Joining Fabric to Metal
These screws have a free-rotating, permanently attached washer that remains stationary while tightening to prevent bunching while attaching tarps and other fabric to metal. They save you time and effort by drilling their own holes and fastening in a single operation. Made from steel, they're zinc-plated to resist corrosion in wet environments. Length is measured from the edge of the head.

Steel Hex Head Screws for Wood
These steel screws have corrosion-resistant finishes. Also known as lag bolts, they have a hex head for a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from under the head.
Zinc-plated steel screws resist corrosion in wet environments.

Steel Rounded Head Thread-Forming
Screws for Brittle Plastic
These steel screws have alternating high and low threads to minimize cracking and splitting in brittle material such as phenolic and glass-filled plastic. Length is measured from under the head.
All of these screws are zinc plated to protect the steel from corroding in wet environments. Black zinc-plated screws blend in with dark surfaces and reduce glare.

Medium-Strength Metric Class 8.8
Steel Square-Neck Carriage Bolts
These Class 8.8 steel bolts are suitable for fastening most machinery and equipment. They have a zinc or zinc yellow-chromate plating to resist corrosion in wet environments. A square neck keeps them from turning when tightening a nut. A smooth, rounded head provides a finished look. Length is measured from under the head.
