Is it possible to use rivets in my design?

Yes, you can use rivets in your design. We do not stock any rivets, however, we can certainly order them for you (this could lead to increased cost and lead time) and install them in your design.

What studs do you stock?

Protocase stocks many studs in a variety of lengths and threads. View the full list of studs we stock here, as well as a list of non-stock studs that we can order for you in a minimum quantity (subject to vendor availability and may extend manufacturing lead times).

What if you don't stock the fastener I need?

We can order the fastener you need. Please note this may affect our 2-3 day turnaround. Contact us for more information.
