Checkout paper concerning this issue in SEAOC 1996 Proceedings. Over driven nails in 3/8" plywood. Tested walls with 20%, 50% & 80% of nails overdriven. Panels with 20% & 50% overdriven (about 1/8" overdriven; nails driven proud, then flush then set with pin punch to 1/8" depth) performed well when compared to handriven common nails. Panels with 80% overdriven did not perform so well. All nails were nominal 8d nails (common .131" dia, gun nails .113" dia). Sorry I cannot suggest a cheap remedy for this condition unless you can get by with reduced capacity & leave as is. Ask APA for suggestons. regards Robert Kazanjy, PE **Disclaimer: I speak for myself not UC-Irvine** Senior Development Engineer Civil & Environmental Engineering UC Irvine E4130 EG, Zot: 2175 rkazanjy(--nospam--at)uci.edu James Allen wrote: > Earlier this summer there was a thread regarding overdriving nails > into shear wall sheathing.
