All measurements are in mm Metric 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.

4 Type B simply have square/straight ends. Aspen Fasteners offers over 500,000. unique fastener products from stock in inch and Metric standard in a variety of materials and finishes.

Austenitic steel is by far the most common type (>90% of commercial fasteners). The steel groups and strength classes are designated by a four-digit sequence of letters and numbers (eg A2-70) as shown in the following table.

7 DIN EN ISO 3506 governs screws and nuts made from stainless steel. Screws, Nuts and Bolts Tensile Tensile Strength strength strength Dia range Nut Load Steel group Steel grade N/mm2 PSI. class N/mm2. 50 500 70,000 <=M39 500. Austenitic A2 and A4 70 700 100,000 <=M20 700. 80 800 118,000 <=M20 800. The tensile stress is calculated with reference to the tensile stress area (see DIN EN ISO 3506-1979).
