M5 Class 8.8 Metric Zinc Plated Set Screws / Full Thread Bolts Main Page

Lengths from 12mm up to 40mm in 5mm increments 

Description: M5 Class 8.8 metric zinc-plated set screws, also known as full thread bolts, are essential fasteners used in various mechanical and construction applications. These bolts are characterized by their fully threaded shank, making them ideal for creating strong and secure assemblies in metal-to-metal and metal-to-wood connections.

Material and Plating:

• Material: High-strength steel (Class 8.8), known for its robust mechanical properties and excellent tensile strength.
• Plating: Zinc plating provides a protective coating that enhances corrosion resistance, making these bolts suitable for both indoor and outdoor use.

Specifications:

• Thread Size: M5 (5mm diameter)
• Length: Varies (customizable according to application needs)
• Thread Pitch: Standard metric coarse thread pitch (0.8mm)

Torque Recommendations:

• Dry Torque: Approximately 6 Nm (Newton-meters)
• Lubricated Torque: Approximately 5 Nm (Newton-meters)

These torque values ensure optimal clamping force without over-tightening, which can lead to bolt or component failure.

Spanner Size:

• Spanner/Wrench Size: 8mm Use an 8mm spanner or socket for tightening and loosening M5 set screws/bolts.

Drill and Tap Links and Information:

• Drill Size for Tapping: 4.2mm To create a threaded hole for an M5 bolt, use a 4.2mm drill bit before tapping.
• Tap Size: M5 x 0.8 Use an M5 x 0.8 tap to cut the internal threads in the drilled hole, ensuring a perfect fit for the M5 bolt.

Applications: M5 Class 8.8 metric zinc plated set screws/full thread bolts are widely used in:

• Machinery and equipment assembly
• Automotive and aerospace industries
• Construction and structural applications
• DIY and home improvement projects
• Furniture and cabinetry

These versatile fasteners provide reliable performance in demanding environments, ensuring secure and durable joints.

By adhering to the torque recommendations and using the appropriate tools for installation, these set screws/bolts will deliver optimal performance and longevity in your projects.
