Metric DIN 7349 thick flat washers for bolts with heavy type spring pins are circular flat washers with a central hole that are. thicker and have a larger outer diameter OD than the most commonly used metric flat washer DIN 125 Consequently the. DIN 7349 thick flat washers have a larger surface area and are used where larger bearing surfaces are required. Aspen Fasteners offers over 500 000 unique fastener products from stock in inch and metric standard in a variety of materials. and finishes The following sizes of DIN 7349 thick flat washers are available for immediate shipping from stock Diameters. ranging from M3 to M30 in regular zinc plated steel and stainless steel A2 and stainless steel A4 View parts by clicking on the. following link Metric DIN 7349 Thick Flat Washers or contact our knowledgeable and friendly sales staff for more information. and or an immediate quote, DIN Deutsches Institut f r Normung German Institute for Standardization standards are issued for a variety of components. including industrial fasteners as Metric DIN 7349 thick flat washers for bolts with heavy type spring pins The DIN standards. are commonly used in Germany Europe and globally even though the transition to ISO standards is gradually taking place. DIN standards continue to be used for parts which do not have ISO equivalents or for which there is no need for. standardization as DIN 7349 thick flat washers, 1 Mechanical properties of stainless steel for metric DIN 7349 thick flat washers. Stainless steels can be divided into three groups austenitic ferritic and martensitic 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 DIN EN ISO 3506 governs screws and nuts. made from stainless steel,Screws Nuts and Bolts,Steel group Steel grade Strength class. Tensile strength Nut Load,strength Dia range,N mm2 N mm2. 50 500 70 000 M39 500,Austenitic A2 and A4 70 700 100 000 M20 700.
