    Product is a generally thick, ring-shaped washer used in conjunction with threaded fasteners like bolts and nuts. It is designed to increase contact area of bolt head or nut with material surface, thereby distributing applied force over a wider area. This reduces stress concentration that might occur on mounting surface, prevents loosening, and lowers risk of damage in softer materials (e.g., wood or plastic). Product's primary purpose is to increase strength and durability of connection.

  • Material: Carbon steel (Typically ST37 or similar structural steel) or stainless steel (A2/A4).

  • Standard: Generally DIN 125 (Type A or B) or DIN 9021 (Wide series).

  • Coating: Hot-dip galvanizing (HDG) or electro galvanizing (zinc plating) for corrosion resistance.

  • Dimension: Metric sizes corresponding to bolt diameter in terms of inner diameter, outer diameter, and thickness (mm).
