Hex Head Lag Screws

Hex Head Lag Screws: Cost-Effective Zinc Plated or Unfinished Plain Steel Options for Reliable Timber Fastening
 
Hex head lag screws are the cost-effective workhorses of timber construction—practical, reliable, and built to get the job done without breaking the bank. These versatile lag bolts deliver strong holding power for securing brackets to beams, joining timbers, mounting hardware, assembling barn doors, and completing a wide range of structural and decorative projects.
 
At Cutting Edge Metals, our hex head lag screws are available in two practical finishes to suit your needs:
  • Zinc Plated — Bright, corrosion-resistant coating that offers solid protection and a clean professional look. The most popular choice for general use and a great, affordable addition to any bracket package.
  • Unfinished Plain Steel — Bare metal with no coating, allowing natural rust patina to develop over time for a raw industrial or rustic appearance. Ideal when you want to apply your own finish (paint, oil, or clear coat) or prefer an authentic weathered look.
The hex head design makes installation quick and easy with standard wrenches or our matching hex head sockets—no slipping or stripped heads, just solid torque every time. Coarse threads and a sharp tapered point ensure deep bite and excellent pull-out resistance in wood.
