| Title | <p>This document specifies mechanical and physical properties of flat washers, designed to be used in bolted joints in combination with bolts, screws, studs and nuts with a specified property class in accordance with ISO 898‑1 and ISO 898‑2.</p> <p>NOTE 1 These types of washers can also be used with other fasteners such as screws forming their own mating thread.</p> <p>Washers that conform to the requirements of this document are evaluated at an ambient temperature range of 10 °C to 35 °C. They might not retain the specified mechanical and physical properties at elevated temperatures and/or lower temperatures.</p> <p>NOTE 2 Washers conforming to the requirements of this document are used in applications ranging from −50 °C to +150 °C. Users are advised to consult an experienced fastener expert for temperatures outside this range and up to a maximum temperature of +300 °C when determining appropriate choices, or for critical applications.</p> <p>This document is applicable to the following flat captive and non-captive washers made of carbon steel or alloy steel, with thickness from 0,2 mm to 12 mm:</p> <p>— plain washers (with or without knurls, ribs or chamfers);</p> <p>— square washers;</p> <p>— square hole washers;</p> <p>— shaped plates.</p> <p>It does not specify requirements for the following properties:</p> <p>— corrosion resistance;</p> <p>— weldability.</p> |
