Rampa bolts

Ramps bolts are an excellent choice that pairs perfectly with Rampa threaded inserts. I had not used either prior to my past order, but they worked so well that I will always use Rampa products on my woods projects.

Farm Table Top

I used the Rampa bolts to attach c-channel to my daughter’s farm table build. They were easy to install and worked great. The top is flat and stable. I will surely use this product again.
