Our rivets are wonderfully low-mass and more subtle than typical off-the-shelf rivets. Use a 3/32" drill-bit. Low mass means they are as small & light-weight as possible while still be strong enough to do their job perfectly.
For push-button connections, use a Rivet to fasten one half of the connector into your tubing and a push-button to fasten the other half. Drill & Rivet Gun needed for installation.
