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. Dia. 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 2-1/2 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

nope. #9 is .177" (about 11/16"). For 1/4" you'd want a #14 screw, more likely labeled as a 1/4" screw.

Can these be used on pressure treated balusters or should i use something else?

Asked by MrB October 1, 2018

Answers

No - they would probably split - I use GRK multi purpose screws for that

Would these screws be the proper length for a load bearing shelf?

Asked by DepotLou August 21, 2018

Answers

Not really used for that. These are specifically for Samson hangers. I would use a 3.5" or 4" GRK fasteners. They are expensive but strong as heck.
