These stainless steel hex head lag screws are for contractors, maintenance teams, and other commercial buyers securing heavy lumber or other materials under demanding loads. They provide a larger fastening option when standard wood screws are too short or too small.

Each lag screw measures 5/16 in. x 3-1/2 in. and is made from 304 stainless steel. The 100-pack can be used with lag shields for masonry applications involving concrete, brick, and mortar. A pilot hole may be pre-drilled in some applications to help prevent splitting or snapping.


Key Features:

  • 304 stainless steel: Provides stainless steel construction for fastening tasks.
  • 5/16 in. x 3-1/2 in. size: Offers a larger lag screw option where standard wood screws do not provide enough length or size.
  • Hex head design: Supports installation with a compatible hex-driving tool.
  • 100-piece pack: Supplies multiple screws for project and maintenance needs.
  • Lag shield compatibility: Allows use with lag shields in concrete, brick, and mortar applications.

Choose these 5/16 in. x 3-1/2 in. stainless steel lag screws for heavy lumber connections and compatible masonry fastening with lag shields.
