Steel flat washer (black baked finish) / FFW-B
Steel flat washer (black baked finish) / FFW-B
This product is a flat washer made from high-strength steel (iron) with a black baked finish on the surface. It is used by inserting it between the fastener and the workpiece during the tightening of bolts and screws. By distributing the load when tightening screws over a larger area, it reduces the stress on the tightening surface, helps prevent dents and scratches on the workpiece, and protects the seating surface. Additionally, using a flat washer stabilizes the fastening surface and supports the tightening condition of bolts and screws. In addition to the mechanical strength characteristic of steel, it features a calm black appearance due to the black baked finish on the surface. With its black finish that minimizes light reflection, it is suitable for assembling various devices and enclosures where visibility is not desired, including internal parts of equipment, while also considering the overall design.
