M8 Class 8.8 Metric Zinc-Plated Bolts Full Range Metric Coarse
Description: M8 Class 8.8 metric zinc-plated bolts are high-tensile fasteners designed for demanding applications in mechanical, structural, and industrial fields. These bolts are known for their exceptional strength and durability, making them suitable for heavy-duty tasks. The zinc plating provides excellent corrosion resistance, ensuring that the bolts maintain their integrity and performance over time, even in harsh environments.
Material and Plating:
- Material: High-tensile steel (Class 8.8), offering superior mechanical properties and high tensile strength.
- Plating: Zinc plating, which provides a protective coating to enhance corrosion resistance and prolong the bolt's lifespan.
Specifications:
- Thread Size: M8 (8mm diameter)
- Length: Available in various lengths to meet different application requirements
- Thread Pitch: 1.25mm (standard metric coarse thread pitch)
Torque Recommendations:
- Dry Torque: Approximately 25 Nm (Newton-meters)
- Lubricated Torque: Approximately 20 Nm (Newton-meters)
These torque values ensure that the bolts are tightened to the correct tension, avoiding over-tightening, which can cause damage to the bolts or the components they secure.
Spanner Size:
- Spanner/Wrench Size: 13mm Use a 13mm spanner or socket for tightening and loosening M8 bolts.
Drill and Taps Links and Information:
- Drill Size for Tapping: 6.8mm To prepare a hole for threading an M8 bolt, use a 6.8mm drill bit.
- Tap Size: M8 x 1.25mm Use an M8 x 1.25mm tap to create internal threads in the drilled hole, ensuring a precise fit for the M8 bolt.
Applications: M8 Class 8.8 metric zinc-plated bolts are widely used 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.
By following the recommended torque values and using the appropriate spanner size and drill/tap dimensions, M8 Class 8.8 bolts will ensure secure, durable, and long-lasting connections in your projects.
