The users of this document are engineers involved in design, analysis or verification of joints on structures used for space missions. It is a guidelines document; therefore it includes advisory information rather than requirements. This document is intended to be applicable to any type of joint that is mechanically connected by threaded fasteners (e.g. bolts, screws, etc). It is written for joints made from metallic materials. However, subject to the engineering judgement of the user, many of the procedures presented herein may be applicable to joints made from composite materials.
