The M3 M4 M5 M6 M24 Dacromet Double Fold Self-Locking Washer is a high-performance fastener designed to protect connected surfaces, prevent fastener loosening, and serve various specialized purposes. These washers comply with DIN25201 standards and are available in multiple materials and finishes.
The self-locking washer consists of two washers with inner bevel tooth surfaces that create lifting tension when subjected to vibration, ensuring 100% locking. Flat washers increase contact area and disperse pressure, while spring washers provide additional friction between nut and bolt.
