They are specialised in this and know which roads to take. To arrive at a maximum result, the organisation must be open to setting up a good quality management system and possibly improve this. Together with the organisation, the QHSE advisor looks at and maps the most important risks. In a joint audit plan, it is agreed which business elements will be scrutinised.
Periodic audits are used to establish whether the organisation continues to meet the established standard and is still ISO worthy. Get Toolshero updates on new methods, models and theories! Join us.

The number to the left of the dot is the tensile strength in MPa divided by The number to the right of the dot indicates the tenfold of the yield point or offset yield ratio.
The property class of a nut is identified with a single number, which corresponds to the highest property class of a screw with which the nut can be paired. A nut of property class 9 can be paired, for example, with a screw up to property class 9.
Threaded fasteners are selected very carefully with regard to their industrial application and are integrated carefully into the design. Accurate determination via tensile tests of the elastic tensile modulus and the limits of elastic loading is essential, since these values determine the limit forces required for a secure, reliable threaded connection.
All variations of the tensile test Sections 9. For full-size fasteners, the tests defined in sections 9. Deciding factors for the dimensioning of a testing machine are the size and strength of the fasteners to be tested. The use of hardened specimen grips allows for efficient testing of finished fasteners, as well as turned screws and bolts and set screws. The specimen with corresponding specimen holder is inserted into the specimen grips, which are freely accessible from the front, and centers itself in the tensile axis.
An extensometer is required to determine offset yield points. For tensile testing of turned screws, any common extensometer can be used—from a contact version such as the makroXtens to the non-contact videoXtens. The proof load test section 9. The exact test load depends on the thread, diameter of the fastener and the property class. These are listed in a table in ISO
