Dear Customer,
As you may be aware of in march 2009 ISO published the revision of spec. 898-1 “Mechanical properties of fasteners made of carbon steel and alloy steel -- Part 1: Bolts, screws and studs”. This spec. was finally approved on July 9th 2009.
The new edition, contrary to the previous one, requires for the material of class 8.8 a sufficient hardenability to ensure a structure consisting of approximately 90% martensite in the core of the threaded section for the fasteners in the “as-hardened” condition before tempering.
Bontempi Vibo would like to point out that its whole production, even before year 2009, fulfils the spec. requirements.
We would also like to inform you that all our screws have been manufactured in our Italian plants.
If you need any further clarification, please feel free to ask us at any time.
Best Regards
Vittoriano Calomeni
