ISO 8981: 2013 is applicable to bolts, screws and studs. made of carbon steel or alloy steel, having triangular ISO metric screw thread in accordance with ISO 681, with coarse pitch thread M1, 6 to M39, and fine pitch thread M8x1 to M39x3, with diameterpitch combinations in accordance with ISO 261 and ISO iso 898 1 class 9.8

ISO 898 consists of the following parts, under the general title Mechanical properties of fasteners made of carbon steel and alloy steel: Part 1: Bolts, screws and studs with specified property classes Coarse thread and fine pitch thread. Part 2: Nuts with specified proof load values Coarse thread. ISO 8981 was prepared by Technical Committee ISOTC 2, Fasteners, Subcommittee SC 11, Fasteners with metric external thread. This fifth edition cancels and replaces the fourth edition (ISO 8981: 2009), of which it constitutes a minor revision. Hiroaki, S. Verification of the Design Concept in BoltNut Assemblies for the revision of ISO 8982 and ISO 8986, Journal of Advanced Mechanical Design, Systems, and Manufacturing, vol. 1, iso 898 1 class 9.8 Nov 16, 2006 I note that ISO 8981 limits the boron content of material used to fabricate property class 10. 9 fasteners to. 003 (. 005 provided that noneffective boron is controlled by addition of titanium andor aluminum ). ISO 898. 6. Nuts with specified proof load values Fine pitch thread 7. Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm With exception to part 7, which defines test standards, the parts of this standard define properties for fasteners made of ISO 8981: 2013 specifies mechanical and physical properties of bolts, screws and studs made of carbon steel and alloy steel when tested at an ambient temperature range of 10 C to 35 C. F568M07 Standard Specification for Carbon and Alloy Steel Externally Threaded Metric Fasteners (Withdrawn 2012) this specification was withdrawn in January 2012 because ISO 8981 is the preeminent world standard for metric externally threaded fasteners. 1. 1 This specification covers chemical and mechanical requirements for nine
