JD Rivets are a series of rivets that have different head shape in an existing series of "negative mold".

JD rivets are shaped with a single dot in a circular shape (jog-dial), which is often found in missile hatches, bullets, and round articulations. The "Negative Mold" used to replace these parts, but the HS rivets and US rivets will increase your choice.
