Strong-Drive® XL LARGE-HEAD METAL Screw 

Strong-Drive® XL LARGE-HEAD METAL Screw

Strong-Drive XL® Large-Head Metal screws are load-tested and code-listed, allowing you to get the for maximum load values for installation. These screws are the perfect choice when high shear or uplift resistance is required and can be excellent 1-for-1 replacements for pins.

Key Features

  • 5/16" hex drive (driver part #BITHEXLB516)
  • #5 drill point
  • Quik Guard® coating
  • 5/8" diameter hex washer head
  • Available collated.

Applications

Steel decking or other cold-formed steel framing or connectors to structural steel supports up to 3/8" in thickness where high shear and pullover values are needed.
