WASHERS
DIN 125
Flat Washers
Current norm: DIN 125, ISO 7089
Materials: Iron, Steel, Stainless Steel
Hardness: 100HV, 140HV, 200 HV, 300HV
Coatings: Plain, Zinc Plate, Zinc Flake, HDG
DIN 125 Flat Washers are standard metric flat washers – a circular metal disc with a central hole. Typically used to distribute the load over a larger bearing surface either positioned below the head of a bolt or below the nut. This even distribution over a larger area reduces the chance of damaging the bearing surface. A washer could also be used if the outer diameter of a mating nut is smaller than the hole through which the screw is placed.

DIN 9021
Large Plain Washers
Current norm: DIN EN ISO 7093-1, ISO 7093
Materials: Iron, Steel, Stainless Steel
Hardness: 100HV, 140HV, 200 HV, 300HV
Coatings: Plain, Zinc Plate, Zinc Flake, HDG
DIN 9021 Flat Fender Washers are round flat washers with a larger outer diameter (OD) approximately 3 x inner diameter (ID). These larger OD washers are typically used to distribute the load over a larger bearing surface than a standard flat washer. The washer is to be positioned below the head of a bolt or below the nut. This even distribution over a larger area reduces the chance of damaging the bearing surface. A washer could also be used if the outer diameter of a mating nut is smaller than the hole through which the screw is placed.

DIN 127 B
Spring Washers
Current norm: DIN 127 B
Materials: Iron, Steel, Stainless Steel
Hardness: 100HV, 140HV, 200 HV, 300HV
Coatings: Plain, Zinc Plate, Zinc Flake, HDG
DIN 127 Helical Spring Split Lock Washers are commonly used metric lock washers – It is a split metal ring that is bent into a helical shape. Split Lock Washers are a left hand helix and allow the nut to be tightened in a right hand direction only. When compressed by tightening the nut, the washer bites into the substrate and exerts a spring force between the bolt and the substrate creating frictional resistance to rotation. DIN 127 are available in two forms, type A and type B. Type DIN 127 A have bent up tang at both ends of the washer. Type B simply have square/straight ends.

DIN 128 A
Curved Spring Lock Washers
Current norm: DIN 128 A
Materials: Iron, Steel, Stainless Steel
Hardness: 100HV, 140HV, 200 HV, 300HV
Coatings: Plain, Zinc Plate, Zinc Flake, HDG
DIN 128 Type A and B Spring Lock Washers are specialty spring lock washers – Both are split metal rings that are bent into a curved (Type A) or waved configuration (Type B). Unlike standard split helical spring lock washers, the DIN 128 lock washers are non-directionally specific allowing the screw and or nut to be tightened in a clockwise or counter-clockwise manner. When compressed by tightening the nut, the DIN 128 lock washer exert a spring force between the tightened bolt and the substrate creating frictional resistance to rotation.

Coatings: Plain, Zinc Plate, Zinc Flake, HDG
DIN 6796 Conical Spring Washers for bolted connections are conical shaped washers that act as heavy duty spring discs when loaded in the axial direction. They are designed to be used in bolted connections where they help prevent loosening or unfastening of the connection due to thermal expansion/contraction and/or vibrational forces.
