• Flat washer with large ratio of outer diameter to inner diameter.
• Since the seat surface is wide, it is suitable for soft members like wood.
• The nominal diameter is the diameter of the external screw used, and the inner diameter of the washer has a slightly larger hole.
• Made of steel with UNIQLO plating (light blue color) to improve corrosion resistance.
• Especially large outside diameter washer.
• It is used to distribute surface pressure when fastening with bolts, nuts, etc., to prevent damage to the mating member, and to prevent caving when the bottom hole is large.
• Has more corrosion resistance than fabric.
