F436 Flat Steel Washer, 1/4'' - 4'', Black Oxide For Oil And Gas Industry
Standard:F436
Description:
The F436 Washer is specified by the ASTM F436 standard, which ensures that the washer meets specific requirements for its dimensions, material composition, hardness, and performance. This standard is widely recognized and used in North America for structural applications.
The Zinc Plated Washer refers to the surface treatment applied to the washer. Zinc plating provides a layer of corrosion resistance, which helps protect the washer from rust and other forms of degradation. This makes the washer suitable for use in both indoor and outdoor environments, especially in applications where exposure to moisture or other corrosive elements is a concern.
