Thread-Forming Screws for Joining Wood to Metal
Thread-forming screws press threads into drilled holes for a tight vibration-resistant assembly. All are beveled under the head for use in countersunk holes. A Torx drive allows you to apply extra force with less slippage or damage to the recess. They're black-phosphate steel to resist corrosion in dry environments. Length is measured from the top of the head.
