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.
