Connector Screws for Secure Wood Connections

Connector screws are specially designed to fasten structural connectors such as joist hangers, straps, post bases, and other hardware to wood. They provide superior holding power compared to nails, ensuring long-lasting, code-compliant connections that stand up to demanding loads. Whether you’re building a deck, framing a home, or installing heavy-duty structural connectors, connector screws make installation stronger and easier.

Why Choose Connector Screws?

  • Code-Approved: Many connector screws are ICC-ES approved for use in structural applications.
  • Enhanced Holding Power: Designed with deep threads and specialized shanks for maximum grip in wood.
  • Faster Installation: Drive easily without pre-drilling, saving time compared to traditional nails or bolts.
  • Corrosion Resistance: Available in coated and stainless steel finishes to perform in outdoor or treated lumber applications.
  • Precision Fit: Engineered to work seamlessly with connectors from top brands like Simpson Strong-Tie.

When to Use Connector Screws

Connector screws should be used whenever you’re fastening structural hardware that requires reliable load transfer. Common applications include:

  • Attaching post bases and post caps
  • Securing joist hangers and framing hardware
  • Installing straps, angles, and tie-downs in wood framing
  • Deck construction and outdoor structures where code compliance is critical

If your project involves structural connectors, dedicated connector screws are the safest and most efficient fastening option.

Connector Screws FAQ

What makes connector screws different from regular screws?

Connector screws are engineered specifically for structural hardware installation. They feature shorter lengths, large diameters, and optimized threads to maximize shear strength and grip, unlike standard wood screws.

Can I use nails instead of connector screws?

Approved nails are acceptable, but connector screws generally provide stronger, more reliable, and code-compliant connections. They also make installation easier since they’re less likely to back out or loosen over time.

Are connector screws approved for outdoor use?

Yes. Many connector screws are available with corrosion-resistant coatings or in stainless steel, making them suitable for exterior and pressure-treated lumber applications.

Do I need to pre-drill for connector screws?

No, most connector screws are self-tapping and can be installed directly into wood without pre-drilling. This speeds up installation while reducing splitting.
