Ideal for deck building and exterior wood projects
Made for flat or oval head screws for a finished look.
Designed with sharp teeth as a great locking mechanism, tooth lock washers create a ratchet action by biting into the material and surfaces they contact. Ideal for situations where potential loosening from corrosion or vibration is a concern, tooth lock washers are used to prevent nuts and bolts from coming loose. These fasteners contain teeth around the outer diameter that help bite into the joint material, thus providing a locking feature when tightened beneath a nut. The zinc finish provides rust resistance. Use with treated lumber in applications with like nuts and bolts of similar diameter.
Internal Tooth Lock Washers bite into the screw head while the smooth, outside rim won't snag objects. Provide greater vibration resistance than split lock washers. Used with fasteners that have small heads. Zinc-plated steel washers are corrosion resistant in wet environments.
