These are extra large and sturdy tubular brass rivets, suitable for making and mending heavy cases and strapwork, where the leather is very thick.
They have a cap on both ends so they look the same on the front and back and are very good for items where both sides of the rivet are seen.
The caps measure 11mm and the stem is 12mm long.
To use these rivets, push the stem through a hole in the leather that you want to join together, put the cap on top of the stem, and with a hard surface such as a metal vice underneath, tap the cap with a hammer. For a smooth and rounded finish to your rivet heads, you can use a rivet fixing tool.
This is a pack of 10 extra large rivets. A smaller double cap rivet is also available.
