| Steel 8.8Steel 8.8 Tensile strength Rm ≥ 800 MPa, yield Rp0.2 ≥ 640 MPa (80 % of Rm). The everyday property class for machine parts. The property class this standard is usually made in.usual | 33.6 | 46.4 | 28.8 | 53.9 | Calculate torque |
| Steel 10.9Steel 10.9 Tensile strength Rm ≥ 1040 MPa, yield Rp0.2 ≥ 940 MPa (90 % of Rm). High strength, for heavily loaded joints. | 48.1 | 60.3 | 42.3 | 79.2 | Calculate torque |
| Stainless A2-70Stainless A2-70 Tensile strength Rm ≥ 700 MPa, yield Rp0.2 ≥ 450 MPa. Austenitic stainless A2 (like AISI 304): general corrosion resistance. | 26.1* | 40.6 | 20.3 | 37.9 | Calculate torque |
* Stainless: load at yield (Rp0.2 × As); ISO 3506-1 gives no proof load.
Stainless steel: the real friction is higher and scatters widely, so the torque shown is only a starting point; type your own µ in the box.
