Outdoor Accents® Structural Wood Screw 

Exterior Wood Screws

This product's information may differ depending on the category of use. You are currently viewing details related to Exterior Wood Screws. You can also view product information related to the categories of: Outdoor Accents® Essentials, Outdoor Accents® Avant Collection™, Outdoor Accents® Mission Collection®

The Outdoor Accents structural wood screw reduces installation time by driving easily without predrilling. When combined with the patented, load-rated Outdoor Accents hex-head washer, the solution delivers the decorative appearance of a bolt connection but with a much easier installation. The structural wood screw is now available in three sizes: 2", 3 1/2" and 5 1/2", and can be used with either the Mission Collection® or Avant Collection™, as well as separately to add flair to any outdoor project.

The 3 1/2" and 5 1/2" screws are ideal for structural applications. They feature a bold thread design that enables superior holding to attach ledgers and other secure connections. The 2" screw is ideal for use with 2x lumber, and for adding style to any DIY project. Note: The 2” screw has lower load values than the 3 ½” and 5 ½” screws. It may not be substituted where the longer screws are required.
