Setup, Compatibility & Care
To achieve the best results, ensure the bolt thread diameter is slightly smaller than the internal hole of the 19mm washer to allow for a proper fit. During installation, simply slide the washer onto the bolt shank before tightening it against the material. For long-term care, while the bright zinc finish is corrosion-resistant, it is recommended to keep the washers in their original packaging in a dry location to prevent early oxidation. If used in exterior applications exposed to constant moisture, periodically check the fasteners for signs of corrosion.
