Description

The Simpson Strong-Tie® SD Connector Screw is the only screw specifically engineered and approved to replace nails in designated Simpson Strong-Tie® connectors. Whether you're framing, installing hangers, or working in tight spaces where a hammer isn’t ideal, this screw delivers superior holding power, speed, and code-compliant performance.

The SD9 and SD10 screws replace 10d and 16d nails respectively, providing stronger single-fastener load capacities than the nails they replace. Each screw features a 1/4" hex head with an integrated washer stamped for easy post-installation inspection. The heat-treated shank is precision-sized to match connector holes, ensuring a tight, secure fit every time.

Finished with a corrosion-resistant galvanized coating, the SD Connector Screw is suitable for both interior jobs and most exterior environments.

Features:

  • Only Screw Approved for Use in Simpson Strong-Tie® Connectors: The SD screw is designed to replace nails and exceed their load capacities in tested applications.
  • More Strength, More Control: Outperforms 10d and 16d nails in single-fastener strength, with easier, more precise installation.
  • Integrated Washer Head: 1/4" hex head with 0.370" diameter washer is stamped for easy identification on the job.
  • Corrosion Resistant: Galvanized finish for long-term durability in interior and many outdoor settings.
  • Convenient Installation – Ideal for tight spaces or overhead work where hammering is a hassle. Hex driver included.

Not getting screwed

I have ordered materials over the past 3 years mostly for seismic/hurricane resistance on a 100 year old timber frame house. Always delivered correctly and timely. Reliable and straight up. Thanks

Thank you! We appreciate the opportunity to earn your business. Thanks, Tammy ~ Fasteners Plus Team
