## 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: Solid screw, great price - This isn’t always the case but, this time they sent five 100qty packs, instead of one 500 pack, which is totally fine with me. I do like using screws instead of the nails just in case I have to take it apart… it’s super hard to disassemble hangers when they are nailed. I’ve used these for most of my Simpson strong tie hanger installations. I generally use these shorter ones when screwing horizontally into the two by to secure the joist hanger. Then use the longer ones like the 2 1/2 for when I’m screwing into something thicker.
Review: Looks like what you get at the home center and works just the same. - I noticed these are slightly different in appearance (stamp on end looks a bit more washed out and harder to read on the batch I received) than what home depot carries, but that doesn't really matter since it's the exact same. A lot of workers make fun of these for their cost over nails, but boy these are great later when you make a mistake and need to take some straps/hangers down.

### ⭐⭐⭐⭐⭐ Good fasteners and hold well. If you can afford their extra cost over nails they are handy to have.
*by M***M on July 1, 2025*

Cost over nails is a factor, but I didn't need a whole lot. I needed more than the $10-12 120-pack at Lowes so buying this larger pack helped to keep cost lower. I used them for attaching joist hangers and hurricane ties for a lean-to and a deck. So-far-so-good. A battery-powered impact driver to get these in weighs less than a nail gun, but you also have to apply more pressure to get it to sink into the wood vs. it just spinning (and getting hot), so that's the pro/con when you're on a ladder putting up hurricane ties. Good to always keep in mind what problem you're trying to solve and what is the best tool to do that. This was a good solution for my problem at least.
