Frequently Asked Questions
QWhat is a DIN 125 galvanized plain washer?
AA DIN 125 galvanized plain washer is a flat washer manufactured to the DIN 125 standard and coated with zinc for corrosion protection. It is widely used to distribute fastener loads and protect contact surfaces in construction and mechanical applications.
QWhat thread sizes are available for DIN 125 washers?
ADIN 125 washers are available for thread sizes M12, M16, M20, M22, M24, M27, M30, and M36, making them compatible with a wide range of standard bolts and screws used in industrial and construction applications.
QWhat materials are DIN 125 galvanized washers made from?
ADIN 125 washers are commonly manufactured from carbon steel or stainless steel. Galvanized carbon steel is recommended for outdoor or moderately corrosive environments, while stainless steel grades (A2/A4) are preferred for highly aggressive conditions.
QHow do I choose the correct DIN 125 washer size?
AMatch the washer to the bolt or screw thread diameter and verify the inner diameter (d), outer diameter (dc), and thickness (h) against the specification table. Ensure all dimensions meet the actual load and surface requirements of your application.
QWhat are the main advantages of galvanized flat washers?
AThe zinc galvanizing layer provides strong corrosion resistance, significantly extending service life in outdoor or humid environments. Galvanized washers also distribute clamping loads evenly across surfaces, preventing damage to the base material and improving overall joint stability.
QIn which industries are DIN 125 galvanized flat washers commonly used?
ADIN 125 galvanized flat washers are widely used in construction, electromechanical equipment, automotive assembly, infrastructure, and general manufacturing — wherever bolted connections require reliable load distribution and long-term corrosion protection.
