What are Large Flange Rivets?
Large flange rivets use a wider head to spread load over a larger area. This helps reduce pull-through and surface damage on thin or soft materials.
When should I pick large flange instead of standard dome?
- Thin gauge sheet where pull-through is a risk
- Soft substrates like plastics and soft aluminum
- Slightly irregular holes that benefit from extra bearing
What drill size for 1/8 in and 3/16 in large flange rivets?
Use a snug, clean hole and deburr both sides. Typical pairings follow.
| Nominal rivet diameter | Recommended hole size (in) | Common drill size |
|---|---|---|
| 1/8 in | 0.129–0.133 | #30 |
| 3/16 in | 0.192–0.196 | #11 |
| 1/4 in | 0.257–0.261 | Letter F |
How do I choose size and material?
- Grip range: match to total stack thickness
- Head placement: when possible, place the large flange on the thinner or softer side
- Materials: aluminum, steel, stainless; consider galvanic compatibility
Common issues and quick fixes
- Head pulls through sheet: move up diameter or use a backing washer
- Rivet spins: hole oversized; step up drill or diameter

FAQs
High-intent answers for choosing and installing large flange rivets.
Where should I place the large flange?
On the thinner or softer side when possible to maximize bearing and reduce pull-through.
Do large flange rivets work with plastic or fiberglass?
Yes. The wider head distributes load. For very soft or brittle materials, consider tri-fold rivets or add a backing washer.
