The Simpson Strong-Tie TF Wood-To-Steel screws are structural fasteners skillfully designed to drill through wood and steel up to 15/32" thick. This screw provides excellent pull-through resistance due to its flat head with nibs that easily countersink into the wood. The #5 drill point with wings bores through the wood before drilling into the steel member. Simpson's TF Wood-To-Steel screws have a straight collation compatible with Quik Drive® auto-feed screw driving systems. Additionally, the 750 count pack includes (2) driver bits (replacement bit BITTX30).
