Also since bolts and screws with threads greater than M3 LID to anproximately Ml0 often cannot be subjected to a tensile test or proof load test due to their short lengths, minimum, breaking torques have been specified for bolts and screws Ml to Ml0 ineluding the fine pitch threads M8 x 1: The minimum breaking torques hexagon socket set screws.
Each member body interested in a subject for which a technicai committee has been established has the right to be represented on that committee. Nuts with specified proof load values — Coarse thread  5. IS0 consists of the following ical properties of fasteners: The minimum breaking torques have been determined on the basis of cross-sections resulting from the minimum values of the minor diameter of the thread tolerance 6g.
Apply the torque in a continuously increasing manner. Part 1 does not specify properties for fasteners that have head geometries that reduce the shear strength of the fastener, such as low head screws and countersunk heads.
