💡 Selection & ordering: Choose rivet diameter based on hole size. Select rivet length so that the total material thickness falls within the rivet's grip range. Packaging: “As per Your Choice” – order the exact diameter, length, and quantity you need. All rivets are A2-70 stainless steel (body & mandrel).
🔧 Open end vs. sealed: These are open-end (standard) rivets. They are suitable for general-purpose applications where water/air tightness is not required. For waterproof joints, consider our sealed closed-end rivets (sold separately).
❓ Frequently Asked Questions – Dome Head Stainless Pop Rivets
What drill size should I use for each rivet diameter?
📏 3mm rivets → 3.1mm drill bit. 4.0mm rivets → 4.1mm bit. 4.8mm rivets → 4.9mm bit. 5.0mm rivets → 5.1mm bit. Using the correct drill size ensures proper mandrel expansion and a tight joint.
Are these rivets suitable for outdoor or marine use?
🌊 Yes – A2-70 stainless steel (304 grade) provides excellent corrosion resistance for outdoor furniture, marine trim, coastal environments, and general industrial use. They will not rust like carbon steel rivets. For continuous saltwater immersion, consider A4 (316) stainless, but A2 is perfect for most exterior applications.
How do I choose the correct rivet length (grip range)?
📐 Measure the total thickness of the materials being joined. Select a rivet with a length that slightly exceeds that thickness. As a rule, the rivet length should be about 1.5–2mm longer than the total material stack. Use our length chart as a reference; longer rivets accommodate thicker stacks.
Can I install these rivets with a standard hand rivet gun?
✅ Yes, these are standard open-end blind rivets compatible with most manual, cordless, or pneumatic rivet guns. Ensure your tool has the correct nosepiece for the rivet diameter (3mm, 4mm, 4.8mm, or 5mm). Stainless steel mandrels are strong but set easily with quality tools.
What is the difference between dome head and countersunk head rivets?
🔘 Dome head rivets have a rounded head that sits above the surface, providing a finished look and good bearing area. Countersunk (flat) head rivets sit flush with the surface for a smooth finish. Dome heads are easier to install and more common for general-purpose fastening.
