About Class 10.9
Class 10.9 is a high-strength metric fastener grade, one step above the Class 8.8 standard used in most general-purpose automotive and industrial applications. At 1,040 MPa minimum tensile strength — roughly 30% stronger than Class 8.8 — it's built for applications where joint integrity under sustained load and vibration is critical.
The "10.9" designation reflects the grade's tensile and yield properties under ISO 898-1: a nominal tensile strength of 1,000 MPa and a yield-to-tensile ratio of 0.9. In practice, this means Class 10.9 maintains clamping force in high-vibration environments where Class 8.8 hardware may loosen over time.
Zinc plating provides corrosion resistance for indoor shop use and most equipment applications. For outdoor, marine, or high-moisture environments, consider our stainless steel assortments.
