Strong-Point 1/4-20 x 3-1/2" Phillips Flat Head Reamer w/Wings Self-Drilling Tek Screws WAR Coated

Strong-Point 1/4-20 x 3-1/2" Phillips Flat Head Reamer w/Wings Self-Drilling Tek Screws are designed for attaching lumber or headers to steel. The reamer wings enlarge the hole in the wood before contact with the steel substrate, helping prevent jacking action and allowing materials to pull together tightly. The #4 self-drilling point delivers fast, consistent drilling through steel thicknesses from .110" to .375". The WAR coating system provides advanced corrosion protection for demanding outdoor applications and is compatible with ACQ, pressure-treated, and fire-treated lumber.
