  • Engineered Lumber Panel Fastener
    Publication number: 20120183371
    Abstract: A fastener adapted for anchoring engineered lumber panels has a threaded portion with a double included securement thread having an included angle between 15° and 25°. The ratio of the major thread diameter to the minor diameter exceeds 2.0 to provide a large thread surface to resist pull out. The fastener also includes a drill tip having an effective diameter substantially equal to the minor diameter of the thread. The fastener is configured to resist cocking upon being driven into the engineered lumber panel and to resist marring of the panel fascia.
