Hello - These rivets are steel. We do make 1/8" rivets in stainless steel. Look for Arrow rivet number RSST1/8. Thanks for your question. - Your Arrow Fastener Team
From what I understand, the 1/2" pertains to the depth of the material the rivet is securing whereas the 1/8" pertains to the size of the hole the rivet is going through. This hasn't been explained elsewhere but I had to look at a few videos on YouTube.
Hello, The photo is correct. They are 1/2-inch or "long" length. The diameter is 1/8". Thanks. -- Your Arrow Fastener team
Hey Ricco, Arrow’s aluminum rivets should fasten your steel gutters just as well as steel rivets would. In fact, the aluminum rivets should not rust like steel rivets eventually would. And Arrow's aluminum rivets come in white finish, as well as unpainted. One tip we'd give would be to touch up the drilled holes in the steel gutter with paint before fastening with aluminum rivets to help deter the exposed steel from rusting prematurely; you could also spray 2 layers of clear coat to the exposed steel to help with this. If you have any other questions or if you'd like to chat with us directly about this, feel free to reach out to firstname.lastname@example.org or 800-776-2228. -Your Arrow Fastener team
