Question?The ‘12.9’ is the property class according to ISO 898-1. The ’12’ indicates a nominal ultimate tensile strength of 1200 MPa, and the ‘.9′ means it will remain elastic up to 90% of that value (a nominal yield strength of 1080 MPa). This makes them suitable for high-stress applications. Question?Are these screws coated or finished in any way? Question?Screws of property class 12.9 are typically made from alloy steel, quenched and tempered. They usually have a black oxide or thermal blackening finish for minor corrosion resistance and lubricity. For specific coating details, always refer to the manufacturer’s datasheet for the specific lot number. Question?Can I use these M20x60 screws interchangeably with older DIN 912 standard screws? Question?Yes, for the most part. The ISO 4762 standard is the direct successor to DIN 912. While there might be very minor dimensional tolerance differences between the standards over the decades, for almost all practical applications, they are fully interchangeable. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
