    Description

    This study examined nails and screws exposed to ACQ-treated wood for up to 12 months in a controlled environment. The environment (27ºC, 100% relative humidity) was chosen so that comparisons could be made with previous exposure tests run using CCA-treated wood in the same environment. Five types of fasteners (common 8d nail, hot-dipped galvanized 8d nail, 4d aluminum alloy nail, 64-mm electroplated galvanized screw, 64-mm stainless steel screw) were inserted into wood treated with ACQ to a retention of 4 kg m–3 and exposed to a 100% relative humidity environment for periods from 1 to 12 months. The fasteners were cleaned and weighed to quantify corrosion rate.
