What's Included Class 10.9 hex head cap screws — M6x1.0, M8x1.25, and M10x1.5, multiple lengths per size Class 10.9 hex nuts — matching every diameter and pitch in the kit Flat washers and lock washers — one set per size 24-hole metal drawer — QR-coded labeled, delivered together for ease 660 pieces total Specifications Thread standards M6x1.0, M8x1.25, M10x1.5 Grade Class 10.9 Tensile strength 1,040 MPa (approx. 150,900 PSI) minimum Finish Zinc plated Diameters M6, M8, M10 Total pieces 660 SKU ASSTMET24-10.9 Best For European and Asian vehicle repair — M6, M8, and M10 cover the majority of high-stress metric fastener needs on BMW, Mercedes, Volkswagen, Toyota, Honda, and similar platforms Machine shops and assembly operations — Class 10.9 for applications where standard Class 8.8 strength is not sufficient Agricultural and construction equipment — smaller-diameter high-strength fasteners for machinery that demands reliable clamping load Industrial maintenance teams — stocking Class 10.9 M6-M10 keeps work moving without sourcing individual SKUs Fleet shops — servicing imported or metric-spec vehicles where high-strength replacements are required by spec 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.
