FAQs

What is the diameter of these rivets?

These rivets have a shank diameter of 4.8mm.

Can these be used on thick materials?

The 20mm length is intended for joining specific thicknesses; ensure your combined material thickness allows for the rivet to collapse properly.

Are these rivets removable?

No, these are permanent fasteners. They must be drilled out if you need to disassemble the joint.

Do I need a special tool to install these?

A standard manual or pneumatic rivet gun capable of handling 4.8mm diameter rivets will work perfectly.

What is the benefit of the extra-large flange?

The larger flange provides a greater surface area for the rivet head to press against, preventing the material from pulling through the hole.

Troubleshooting

Rivet feels loose after installation

Check that the drill hole is not too large; the hole size must be as close to 4.8mm as possible to ensure a tight fit.

Mandrel does not snap off clean

Ensure your rivet gun is positioned flush against the surface and that you are using a tool compatible with 4.8mm gauge rivets.

Flange is not sitting flush

Ensure there is no burr around the pre-drilled hole that might be lifting the flange away from the material.

Pros and Cons

Pros

  • Extra-large flange ensures a more secure grip on softer or thinner materials
  • Professional black aesthetic blends well with dark surfaces
  • High structural integrity for demanding heavy-duty applications
  • Easy to install with standard riveting tools

Cons

  • Permanent fastening style means they cannot be reused after installation
  • Specific length requirements mean they may not be suitable for extremely thin sheet metal
  • Limited to one specific size compared to adjustable fastener types

Setup, Compatibility & Care

For optimal installation, use a high-quality rivet gun compatible with 4.8mm diameter rivets. 1. Drill a hole slightly larger than the 4.8mm shank (typically 4.9mm to 5.0mm) through all pieces to be joined. 2. Insert the rivet into the gun and then through the pre-drilled holes. 3. Actuate the tool until the mandrel snaps off, indicating the rivet is fully set. To maintain the appearance of the black finish, avoid using heavy solvents or abrasive cleaners. If used in outdoor or high-moisture environments, regularly inspect for signs of oxidation at the join site, although the materials are designed for longevity.
