3/4" x 18" Conquest Hex Head Lag Bolt for Wood - 18-8 Stainless Steel

This 3/4" x 18" Conquest Hex Head Lag Bolt for Wood - 18-8 Stainless Steel features a 4-1/2 TPI coarse thread and stainless steel construction, built to secure through massive beams and heavy structural wood. With an 18-inch reach, it delivers maximum anchoring depth for jobs that demand strength and long-term stability. Ideal for marine environments, heavy framing, and large outdoor builds where rust resistance and holding power are non-negotiable.

3/4" x 18" Conquest Hex Head Lag Bolt for Wood – 3/4" x 4-1/2 TPI Coarse Thread Stainless Steel Lag Bolt

Use this lag bolt when anchoring stacked timbers, large pilings, or support systems in exposed weather zones. Its stainless steel build holds up to saltwater and harsh climates. With its aggressive thread and long shank, it sets deep and holds fast in heavy-duty woodwork.

Key Features

  • 18" Length: Excellent for ultra-deep penetration in multi-beam installs.
  • 4-1/2 TPI Thread: Delivers maximum bite and resistance to loosening.
  • 18-8 Stainless Steel: Prevents rust in even the harshest conditions.
  • Hex Head Design: Fits common sockets for easy installation.

Common Applications

  • Long beam anchoring
  • Outdoor public works construction
  • Large retaining walls
  • Coastal dock framing
  • Mass timber footings

Installation Tips

  • Start with a long, straight pilot hole to match bolt shaft diameter.
  • Use high-torque tools to seat the bolt fully.
  • Confirm tightness without overtightening to prevent bolt shear.

Stainless Lag Screw Review

I needed an uncommon size, and Fasteners Plus had just what I needed. It was quickly delivered, and the order was accurate, and the quality was excellent.

Small order

I was very satisfied with the lag screws I purchased. My only issue with Fastners + is with the standard shipping cost. Unless I order a large quantity, the shipping cost charged is exorbinate.
