International Standardization for Threaded Fasteners

(Recent Development Activities and their Technical Backgrounds)

Abstract

ISO/TC 2, which are one of the oldest technical committees in ISO since 1947, is responsible for the International Standards for fasteners such as bolts, screws, studs, nuts, pins, rivets and washers on their geometry, sizes, tolerances, mechanical and physical properties, testing methods and quality assurance systems. ISO/TC 2 and its sub committees publishes 195 ISO Standards and 36 ISO Standards are now under development as new Standards or updated ones. This article depicts the recent development activities of ISO/TC 2 concerning the mechanical properties of the threaded fasteners with the technical backgrounds (research works) to justify such activities.
