## Description

Product Description 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. From the Manufacturer Simpson Strong Tie SD Structural-Connector Screws are designed to be used with Simpson Connectors for both interior and exterior applications.

Review: High Strength and high-grade - The screws were high quality.
Review: Strong tight screws - Hanging over 60 4 X4 holders for 4 x 4 beams. This item speeds the work. They even give you the hex head bit to use in the drill. What more can you ask for. Great Product.

These fasteners are amazing. If you’re doing any kind of framing, you’ll know Simpson is the standard. May be more expensive than others, but you get the strength and quality with this brand. They drive easy and hold tough. Only brand I’ll buy.
