Primary Characteristics & Applications for Lag Screws

Lag screws differ from other screws in design and intended application use. Lag screws are large and heavy-duty, featuring coarse threads and a tapered point for driving into wood surfaces. Lag screws can have fully or partially threaded shafts depending on the application requirements. With a larger head size and diameter than typical metal screws, lag screws are designed for load-bearing applications and can attach objects and other materials to wood structures. Common applications for lag bolts include:

  • Structural support for construction applications
  • Securing wood beams, posts, and joists
  • Mounting brackets to walls & ceilings
  • Attaching heavy-duty HVAC components to wood studs or bases
  • Constructing docks & piers in marine applications
