M12 Class 8.8 Metric Zinc-Plated Bolts High Tensile
Description: M12 Class 8.8 metric zinc-plated bolts are high-tensile fasteners designed to meet the rigorous demands of mechanical, structural, and industrial applications. Manufactured to the AS1110.1 / CLASS 8.8 specification, these bolts offer exceptional strength and reliability. The zinc plating enhances corrosion resistance, making them suitable for use in both indoor and outdoor environments.
Specifications:
- Standard: AS1110.1 / CLASS 8.8
- Thread Size: M12 (12mm diameter)
- Thread Pitch: 1.75mm (standard metric coarse thread pitch)
- Length: 30mm
- Finish: Zinc Plated (RoHS Compliant)
Note: Thread length on older stock may vary.
Torque Recommendations:
- Dry Torque: Approximately 85 Nm (Newton-meters)
- Lubricated Torque: Approximately 70 Nm (Newton-meters)
These torque values ensure the bolts are tightened to the correct tension, avoiding over-tightening that can damage the bolts or the components they secure.
Spanner Size:
- Spanner/Wrench Size: 19mm Use a 19mm spanner or socket for tightening and loosening M12 bolts.
Drill and Tap Information and Links
- Drill Size for Tapping: 10.2mm To prepare a hole for threading an M12 bolt, use a 10.2mm drill bit.
- Tap Size: M12 x 1.75mm Use an M12 x 1.75mm tap to create internal threads in the drilled hole, ensuring a precise fit for the M12 bolt.
Applications: M12 Class 8.8 metric zinc-plated bolts are widely utilized in:
- Machinery and equipment assembly
- Automotive and aerospace industries
- Structural and construction projects
- DIY and home improvement tasks
- Furniture and cabinetry construction
These high-tensile bolts provide robust and reliable fastening solutions, capable of withstanding significant loads and stresses. The zinc plating ensures long-lasting performance and durability by protecting the bolts from corrosion.
By adhering to the recommended torque values and using the appropriate spanner size and drill/tap dimensions, M12 Class 8.8 bolts will ensure secure, durable, and long-lasting connections in your projects.
