$64.73The Story
Cover M12, M14, and M16 metric fasteners in one organized 21-hole drawer — Class 10.9 strength for heavy equipment, structural connections, and high-vibration applications where Class 8.8 isn't enough. This 147-piece assortment puts the most common large-diameter metric cap screws, nuts, and washers at your fingertips, pre-sorted and ready to pull from.
What's Included
- Class 10.9 hex head cap screws — M12x1.75, M14x2.0, and M16x2.0, 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
- 21-hole metal drawer — pre-labeled with QR codes
- 147 pieces total
Specifications
| Thread standards | M12x1.75, M14x2.0, M16x2.0 |
| Grade | Class 10.9 |
| Tensile strength | 1,040 MPa (approx. 150,900 PSI) minimum |
| Finish | Zinc plated |
| Diameters | M12, M14, M16 |
| Total pieces | 147 |
| SKU | ASST24MCS109 |
Best For
- Heavy equipment and agricultural machinery — M12 through M16 covers the large-diameter fasteners used in loaders, tractors, and construction equipment
- Commercial vehicle and fleet maintenance — high-strength replacements for structural fasteners on heavy trucks and trailers
- Structural and framing work — Class 10.9 delivers the clamping load required for high-stress structural joints
- Industrial presses and machinery — holds preload under vibration where lower-grade fasteners would loosen over time
- Shops handling a mix of metric equipment — one organized drawer covers the most common large-diameter metric sizes without juggling individual SKUs
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.
