These nickel plated steel rivets have a 7mm stem length and an extra wide 13mm cap size.
They are double capped rivets, which means that they look good from both sides.
To achieve a strong fix, you will need around 2mm of your rivet stem to stand proud of the layers you want to join, before adding the cap and hammering the two halves together.
You can fit these rivets without a fixing tool by resting the stem on an anvil and hitting the cap with a hammer, but this will result in a flattened appearance to the rivet.
If you want to preserve the curved shape of the rivet cap, you will need to use the extra wide rivet fixing tool, shown in related items below.
These rivets are available in packs of 100, 200 and 500.
