ISO 6157-2 Fasteners - Surface Discontinuities - Standard Test for Nuts

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ISO 6157-2 testing. It sets limits for various surface discontinuities in nuts with nominal thread diameters from 5 mm to 39 mm inclusive. It is also valid for all mechanical property classes according to ISO 898-2 and ISO 898-6.

The standard is part of the ISO 6157 series that addresses surface discontinuities in fasteners, including bolts, screws and nuts. Surface discontinuities refer to irregularities or defects on the surface of the fastener that can affect its performance or integrity.

The focus of this standard is to determine the acceptable limits of any defects on the surface of nuts. Surface defects may include cracks, notches, or other similar defects that may specifically affect the performance and reliability of fasteners.

ISO standards are often designed to meet specific industry standards and quality requirements. This standard's identification and evaluation of surface defects in nuts is intended to provide a certain level of quality to manufacturers, users and other interested parties.
