Our GI Big OD Flat Washers are manufactured to DIN 9021 specifications, featuring a larger outer diameter than standard washers (such as DIN 125). This provides improved load distribution and prevents surface indentation, especially on softer base materials like wood or aluminum.
Zinc-coated (galvanized iron) surface ensures basic corrosion resistance for indoor and general-purpose outdoor applications. These flat washers are ideal for use under bolt heads or nuts to spread clamping force and prevent fastener pull-through.
The DIN 9021 standard makes these washers widely interchangeable with international equivalents, supporting efficient maintenance, assembly, and replacement workflows.
Roxon Fasteners – the wholesale fasteners supplier in UAE – delivers high-volume stock of DIN 9021 GI Big OD Flat Washers for contractors, assemblers, and industrial buyers across Abu Dhabi, Dubai, and the GCC.
