ISO 898-5:2012, Mechanical properties of fasteners made of carbon steel and alloy steel – Part 5: Set screws and similar threaded fasteners with specified hardness classes – Coarse thread and fine pitch thread

ISO 898-5:2012 specifies mechanical and physical properties of set screws and similar threaded fasteners made of carbon steel or alloy steel when tested at an ambient temperature range of 10 �C to 35 �C. Fasteners (the term used when set screws and similar threaded fasteners are considered all together) which conform to the requirements of ISO 898-5:2012 are evaluated at that ambient temperature range.Fasteners according to ISO 898-5:2012 are classified to specified hardness classes and are intended for use under compressive stress only.ISO 898-5:2012 is applicable to set screws and similar fasteners:made of carbon steel or alloy steel,having a triangular ISO metric screw thread according to ISO 68-1,with a coarse pitch thread M1,6 to M30, and fine pitch thread M8�1 to M30�2,with diameter/pitch combinations according to ISO 261 and ISO 262, andhaving thread tolerances according to ISO 965-1 and ISO 965-2.
