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

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.

These steel screws have corrosion-resistant finishes.

These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low clearance applications or jam one against a hex nut to hold it in place.

Also known as Keps and K Lock nuts, these locknuts have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance.

About half the strength of medium-strength steel square nuts, use these metric nuts in light duty fastening applications, such as securing access panels.
