Abstract

The effect of incising and preservative treatment on resistance to nail withdrawal was investigated using Douglas-fir and hem-fir lumber. Incising has no significant negative effects on resistance to nail withdrawal for either wood species. Treatment with chromated copper arsenate also had no significant negative effects on nail withdrawal resistance, and ammoniacal copper zinc arsenate treatment was associated with significant improvements in resistance. The results indicate that no changes to current design practices for fasteners are required to account for the use of incised wood.
