This document specifies the mechanical and physical properties of bolts, screws, s tuds and nuts, with coarse pitch thread and fine pitch thread, made of corrosion-resistant stainless s teels (i.e. martensitic stainless steels and precipitation hardening aus tenitic stainless steels) and nickel alloys, intended for use at high temperatures up to 800 °C . Tests in accordance with Clause 9 are performed at the ambient temperature range of 10 °C to 35 °C , and other tes ts can be performed at higher temperatures, see Clause 10. NO TE Fas teners specified in this document are also suitable when used at low temperatures, typically down to -50 °C . For more information, see ISO 3506 - 6 . The term “fasteners” is used in this document when bolts, screws, s tuds and nuts are considered all together. nickel alloys as well as their properties . This document applies to fasteners: — with ISO metric thread in accordance with ISO 68-1 , — with diameter/pitch combinations in accordance with ISO 261 and ISO 262 , — with coarse pitch thread M3 to M39, and fine pitch thread M8×1 to M39×3 , — with thread tolerances in accordance with ISO 965-1 and ISO 965-2 , and — of any shape but with full loadability. Stainless steel and nickel alloy fas tener s ymbols can be used for sizes outside the diameter limits of this document (i.e. for bolts, screws and s tuds with d < 3 mm or d > 39 mm and for nuts with D < 5 mm or D > 39 mm) , provided that all applicable chemical, mechanical and physical requirements are met. Fas teners with reduced loadability (i.e. thin nuts and bolts, screws and studs with head or unthreaded shank weaker than the threaded shank) are not dealt with in this document. This document does not specify requirements for functional properties such as: — torque/clamp force properties, — shear s trength, — fatigue resistance, — weldability, 1 or — properties ofbolted joints and fasteners in high temperature environment (see test methods at high temperature for fasteners in Clause 10).
