Our DIN 436 Square Washers are high quality square flat washers manufactured in strict compliance with the German DIN 436 standard. Made of premium 304 / 316 stainless steel, these square washers provide excellent load distribution, surface protection, and anti-loosening performance for heavy duty mechanical and structural connections. They are widely used in construction, steel structures, railings, brackets, wooden construction, and various industrial assembly applications where a large bearing area and stable support are required.
Compared with standard round flat washers, DIN 436 square washers feature a larger square outer shape, which effectively increases the contact area between fasteners and the connected surface. This design reduces pressure concentration, prevents surface damage, improves connection stability, and avoids bolt or nut sinking into soft materials. With precise stamping, uniform thickness, smooth edges, and no burrs, our square washers ensure perfect fit and reliable performance in long term use.
