This guide is for anyone needing to prevent fasteners from rotating, particularly in applications requiring robust security. The key benefit is its high-strength steel construction and mechanically galvanized finish for superior durability and corrosion resistance, ensuring a secure and long-lasting connection. A potential caveat is that it's designed for specific fastener sizes and may not be universally compatible with all bolt types. This Hillman Anti-Turn Washer is engineered from high-strength steel and features a mechanically galvanized finish, conforming to ASTM A153 standards, to provide a secure, rotation-resistant installation for various applications.

The primary purpose of an anti-turn washer is to prevent fasteners (like bolts and screws) from rotating or loosening due to vibration, stress, or movement in an assembly. This helps maintain the integrity and security of the connection.
Mechanically galvanized finish refers to a coating process where zinc is applied to the steel fasteners through a mechanical plating method rather than hot-dipping. This provides excellent corrosion resistance and a uniform finish, often preferred for certain types of hardware.
This specific washer is designed for 3/8-inch diameter bolts. While it is effective at preventing rotation, its size compatibility is crucial for proper function. Always ensure the fastener size matches the washer.
The primary function of this washer is to prevent rotation. While it distributes the load slightly over a larger area, it is not designed to significantly increase the load-bearing capacity of the fastener itself.
Yes, the mechanically galvanized finish provides good corrosion resistance, making it suitable for many outdoor applications. However, prolonged exposure to harsh environmental conditions might still affect its longevity.
ASTM A153 is a standard that specifies the requirements for hot-dip galvanized coatings on iron and steel hardware. Conformance indicates that the galvanization process meets established quality and performance criteria for corrosion protection.
Ensure the washer is properly seated between the mating surfaces and the nut/bolt head. Verify that the fastener size (3/8-inch) matches the washer and that the components are adequately tightened.
While the galvanized finish offers protection, prolonged exposure to highly corrosive environments may eventually cause degradation. Inspect for damage and consider applying a rust-inhibiting coating if needed for extreme conditions.
Confirm that you are using a 3/8-inch fastener. This washer is specifically sized for 3/8-inch bolts and screws. Check if the fastener has any unusual coatings or dimensions that might interfere with the fit.
Setup: To install the Hillman Anti-Turn Washer, simply place it onto the bolt or screw before threading the nut or fastening the component. The washer should sit between the bolted surface and the nut or bolt head. Ensure the fastener size matches the washer's specification (3/8-inch in this case) for optimal performance.
Compatibility: This washer is designed for 3/8-inch diameter fasteners. It is compatible with bolts, screws, and nuts of the corresponding size. Its primary function is to prevent rotation, so it is best used in applications where this is a concern.
Care: Due to its mechanically galvanized finish, the washer offers good corrosion resistance. For routine maintenance, inspect the hardware periodically for any signs of damage or excessive wear. Clean with a dry cloth if dust accumulates. Avoid using abrasive cleaners or solvents, as these can degrade the protective finish.
