Product Information

Full details

The Timco Flange Head Rivets are ideal for construction professionals and DIY enthusiasts requiring a secure, heavy-duty fastening solution for sheet-to-sheet applications where traditional welding or bolting is impractical. These rivets provide exceptional clamping force and a clean, low-profile finish, making them perfect for structural integrity in steel, aluminum, PVCu, and hard plastic. While they offer excellent durability and corrosion resistance in urban environments, it is important to note that they are not recommended for high-salt or harsh marine atmospheres.

FAQs

What is the required drill hole diameter?

You must use a 4.9mm drill bit to ensure a secure fit.

Can these be used on thick materials?

These rivets are designed for a grip range of 16.0mm to 21.0mm.

Are these rivets suitable for outdoor use?

Yes, they are suitable for urban and industrial environments, but avoid high-salt marine atmospheres.

Which materials are compatible with these rivets?

They are compatible with steel, aluminum, hard plastic, and PVCu substrates.

Do these rivets meet professional standards?

Yes, they comply with DIN 7337 standards for blind rivets.

Troubleshooting

Rivet spins in the hole during installation

The drill hole is likely too large. Ensure you use a 4.9mm drill bit.

Rivet does not pull flush against the surface

Verify that there is no debris between the sheets and that the materials are clamped together before riveting.

Mandrel does not break off cleanly

Check your rivet gun's nose piece size to ensure it matches the 4.8mm rivet diameter and provides enough stroke length.

Pros and Cons

Pros

  • Provides a strong, vibration-resistant connection
  • Suitable for a wide variety of materials
  • Easy to install with standard rivet tools
  • Durable zinc coating protects against surface oxidation

Cons

  • Not suitable for high-salt marine environments
  • Once installed, they are permanent and difficult to remove
  • Requires precise 4.9mm hole drilling for optimal fit

Setup, Compatibility & Care

To install these rivets, use a standard hand or pneumatic rivet gun. Begin by drilling a clean 4.9mm hole through both workpieces, ensuring all burrs are removed for a flush fit. Insert the rivet and actuate the tool until the mandrel snaps off. Regarding care, the zinc and clear Cr3 finish is low-maintenance; however, periodically inspect fastened joints for signs of debris accumulation or environmental degradation in highly polluted areas. Avoid using these rivets in salt-heavy coastal regions as the coating may be insufficient to prevent long-term galvanic corrosion.
