Simpson Strong-Tie SD9112R500 Strong-Drive SD Connector Screw #9 x 1-1/2 in. 1/4-Hex Drive, Mech. Galv. (500-Qty)

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.

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.

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.

They’re screws. They work well in that capacity.

Exactly seller describe on web site, the same quality as Local hardware store very good quality, Price is right, I love it, Highly recommended.... great purchase, it also included the bit in every box to screw that screw.

Up to code work great. However ive found off brand ones gripp on the same wood better. Recommend for code inforced jobs.

Great price and these are great for using with the ufrp plate….makes install very easy!!

Need a lot of these for my deck. Great price for the 500 pack. Saved me a lot compared to the 100 pack from home depot.

Bonne vis, moins cher que grande surface

Went through hundreds of these when building my deck. Don't skimp on quality. Buy these for all your hangers and clips etc.

Nothing wrong can be said about these screws. Good quality and reasonable price. Totally as described.

Pricey but could at least get a bulk box. Work well for the Simpson hangers in our deck project.
