Grade 12.9 Steel Round Head Solid Rivet — GB/T 867 / DIN 660 (Series 097)

When Round Head Solid Rivet — GB/T 867 / DIN 660 (Series 097) are required in Grade 12.9 Steel, the alternative grades and the trade-offs between them matter as much as the dimensions. This page covers both, plus mechanical and corrosion data.

Why Choose Grade 12.9 Steel for Round Head Solid Rivet — GB/T 867 / DIN 660 (Series 097)

The highest common strength class, for high-load machine assembly. For round head solid rivet — gb/t 867 / din 660 (series 097), this matters when requires plating or black-oxide protection is the primary requirement.

Mechanical & Physical Properties

Galvanic & Galling Considerations

For round head solid rivet — gb/t 867 / din 660 (series 097) in steel, the dominant compatibility issue is hydrogen embrittlement at high property classes (10.9 and above) when electroplated. Plating must be followed by an appropriate baking treatment, or a non-electroplated finish (mechanical zinc, zinc flake) should be substituted.

Comparable Grades

For Round Head Solid Rivet — GB/T 867 / DIN 660 (Series 097), class 8.8 is the comparable strength step. Move up when the joint preload approaches the proof load of the current class; move down when the joint is over-specified. For corrosion-critical service, switch to stainless A2 or A4.
