Hose clips

[GMCGoat]

This is going to sound like a dumb question, but I am putting in a new fuel line and I want to know what screw or nut/bolt should I use to hold down my hose clips.

I just want it to look good and not have some sharp screw end coming out the other side of the frame.

Here is what I have as a clip, I could get something else if needed.

I was thinking of just doing some stainless nut/bolts.
