## 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.

## Customer Reviews

### ⭐⭐⭐⭐ Excellent product, but expensive and takes ages to receive it
*by K***N on 10 August 2026*

Excellent product, but it takes ages to receive it and is very expensive

### ⭐⭐⭐⭐⭐ Strong tight screws
*by D***T on 15 December 2024*

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.

### ⭐⭐⭐⭐⭐ Wood not work without them!
*by J***N on 29 November 2017*

These structural screws are AMAZING! The hex head makes it easy for my driver to keep a good grip on them, and the screw pattern just pulls the screw into even the oldest and hardest wood. Honest! I have never felt anything like it! I am working on a home remodel where the wood has been in place for 40 years, and nails are hard to drive in without a gun. These go in like butter. Never thought I would fall in love with the design of a screw!! Better still, because they are structural (and can take shear force much better than other screws) they make installing metal construction connectors a piece of cake! No more bruised thumbs from missing the nail for me, or hard pounding in tight places!!
