Product Overview

The Strong-Drive SD Connector screw is specifically designed to replace nails in certain Simpson Strong-Tie connectors and is the only screw approved for that application. The load-rated SD screw has been tested and approved for use in many popular Simpson Strong-Tie products. In certain applications screws are easier and more convenient to install than nails, and the single-fastener load values achieved by the SD screw exceed those of typical 10d common or 16d common nails. In addition, the galvanized coating makes the SD screw ideal for interior and most exterior conditions.
  • Tested and approved for use in many of Simpson Strong-Tie's best-selling connectors for both interior and most exterior applications
  • Ideal for use in connector applications where more control is desired or using a hammer is inconvenient
  • 1/4-in hex head with 0.37-in diameter integrated washer reduces cam-out and is stamped with the Simpson Strong-Tie "≠" sign and the fastener size for easy identification after installation
  • Shank is specifically designed to match the fastener holes in Simpson Strong-Tie connectors
  • Optimized heat treating for ductility and strength
  • Size: #9 x 1-1/2 in.
  • Hex driver included
  • Mechanically galvanized, Class 55 coating meets the requirements for use in preservative-treated and fire-retardant-treated wood per the 2012 and 215 IRC
  • Quantity: 100
  • Common project applications: remodeling, fencing, storage, cabinets, framing

Solid screws for the price. I've used them over the years on deck joist hangers and mending plates. These screws are much easier to install and stronger than 10d nails. These screws also have a quality galvanized coating. Each box comes with a driving bit and my impact driver drives them very quickly. No need for pre-drilling.

I used these with angle brackets to attach my foundation top plate to the house's floor joists (er, the 2x6 that runs around the perimeter of the house) for seismic reasons. Most went in without a problem (some needed a little help with a hammer to get them started), didn't see any splitting in 60yr old wood. I won't know if they are really good until an earthquake hits, tho. Check back then...

Excellent. Our rental burned down and the structural engineer called for these to upgrade our deck. Used to connect a 4x10 rim joist to the ceiilng joists under the balcony. We used them with the simpson A34 and it's very strong. They may be small, but you have 8 screws per A34. City passed it right away and we'll be using about another 600 soon for the balcony rails.
