Details
Strong-Point 1/4-20 x 3-1/4" Phillips Flat Head Reamer w/Wings Self-Drilling Tek Screws Zinc CR3+ Plated
Strong-Point 1/4-20 x 3-1/4" 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 contacting the steel substrate, preventing jacking action and allowing the materials to pull together tightly during installation. The flat head design provides a flush finish in countersunk holes for a clean, professional appearance. The #4 self-drilling point delivers fast, consistent drilling through steel thicknesses from .110" to .375". Zinc CR3+ plating provides corrosion protection by forming a protective barrier that helps prevent oxidation.
