Notes
Scope: These properties apply to the specified supplier product; it does not certify every Metal-Ad item or establish full conformity to the named DIN/ISO standard.
Property class: 10.9
Hardness: Rc 33-39
Tensile stress: 1040 MPa
Yield stress: 940 MPa
Thread class: 6g
Threads: ANSI B1.13M; ISO 262, coarse series only
Standard reference: DIN 7984 and DIN 6912 are similar specifications only. Alternative DIN 7984 product dimensions may differ.
Torque guidance: Supplier torque values apply to plain screws and are calculated to induce 620 MPa in the threads. They are guidelines only; induced loads may vary by +/-25% with mating interface conditions, lubrication, finish, hardness and bolt/joint compliance. No universal installation torque is specified here.
Finish and supply: No verified Metal-Ad coating or availability is established here.
