ISO/TC 2/WG 13 - Washer and non-threaded fasteners

This document specifies the characteristics of grooved pins with half-length centre oval grooves (with closed ends), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm. These grooved pins are designed to fulfil the main following functions: relative rotation of the assembled parts, and positioning or guiding, with an easy installation (due to its symmetrical shape) and a high level of pull-out resistance (due to the elastic fit behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

This document specifies the characteristics of grooved pins with one-third-length centre oval grooves (with closed ends), in steel and stainless steel, and with a nominal diameter from 1 mm to 25 mm. These grooved pins are designed to fulfil the main following functions: relative rotation of the assembled parts, and positioning or guiding, with an easy installation (due to its symmetrical shape) and a medium level of pull-out resistance (due to the elastic fit behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

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. NOTE 1 These types of washers can also be used with other fasteners such as screws forming their own mating thread. 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. 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. 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: — plain washers (with or without knurls, ribs or chamfers); — square washers; — square hole washers; — shaped plates. It does not specify requirements for the following properties: — corrosion resistance; — weldability.

ISO 4759-3:2016 specifies tolerances for flat washers of product grades A, C and F with nominal diameters of 1 mm to 150 mm inclusive, designed to be used in bolted joints in combination with bolts, screws, studs and nuts. This part of ISO 4759 may be applied to non-flat washers however it does not include all the tolerances related to these washers. It applies to non-captive and captive washers, and to standard and non-standard washers. It does not apply to dynamic disc springs. Washers of product grades F and A are intended to be used with bolts, screws, studs and nuts of product grades A and B; washers of product grade C are intended to be used with bolts, screws, studs and nuts of product grade C. NOTE The product grade refers to a specific tolerance range related to dimensional and geometrical characteristics (product grade F for fine tolerances, product grade A for precise tolerances, product grade C for large tolerances). Annex A presents tolerances taken from ISO 286‑1 and ISO 286‑2.
