Washers provide a greater bearing surface under the fastener. Lock washers place tension against a nut after tightening, to help prevent the nut from loosening.
Lock washers known as split lock washers place tension against a nut after tightening to help prevent the nut from loosening. Ideal for situations where potential loosening from corrosion or vibration is a concern. Lock washers provide a locking spring action and are used to prevent nuts and bolts from coming loose from vibrations. They have split ends that help "lock" into the mating material, thus providing a locking feature when tightened beneath a nut. Hot dipped galvanized finish provides one of the highest degree of corrosion resistance when compared to a steel zinc finish. Ideal for outdoor projects such as decks, fences, wood structures and with treated lumber installations.
Lock Washers provide a locking spring action and prevent fasteners from loosening due to vibration. They are used with a bolt or screw to evenly spread the load over a wider area. Use stainless steel where corrorsion is and rust is of concern or in exterior applications. Best for general hardware use or where high strength is not required.
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.A preferred type of washer when the washer teeth must remain hidden for a finished appearance. Made from 410 stainless steel, these washers have excellent wear resistance. Use stainless steel where corrorsion is and rust is of concern or in exterior applications.
