GRK 772691111371 10 x 3-1/8" Fasteners 11137 RSS Screws 236CT, Gold, 236 Count

You know, every once in a while you run into a product that so out performs everything you've used in its place up 'til then that you are stunned in awe.I bought these in August and it is now late December. Sorry I didn't write a review earlier.These structural screws work better and hold better than anything I've ever used including lag bolts and lag screws. First, they drill their own path whereas a lag bolt or screw requires pre-drilling. Beyond that, these hold better. After driving a lag until the crushing limit of the material there could be movement forced into the joint. No movement with the GRK RSS. From now on, these will be my first consideration on anything structural I construct.BTW: Also bought the  GRK RSS516518HP RSS HandyPak 5/16 by 5-1/8-Inch Structural Screws, 50 Screws per Package  and highly recommend them too!

These screws will go thru 2x lumber like butter !!! I've gone thruogh about half of the pail ,about 100 with nobreakage. Oh, and you might have to set your drill to a lower settings !! or these screws will disappear on you!!!!

screws work great

Very nice screws.

Amazing. Ditch your gold screws from home depot for these. Great for construction where the large head does not get in the way. Some reviewer said these stripped the drivers but I have just completed a shed and had no such problems. Rather than drill into the wood to sinch up a loose connection these screws have a built in washer that tends to stay on the surface of the outer board or plywood and draw the piece into the wood below. This works so well that sometimes I use this first and replace it with a simple grk screw. If you can afford a few more dollars for your project you'll enjoy using these and other GRK products. The larger versions of this screw replace lag bolts and possibly carrage bolts.

Comes with two bits that fits the screw head. They went into the wood easy. My shed is sturdy so no complaints other than being a little pricy

Restoring older buildings

These screws are amazing. They are probably the easiest screw to drive. I used these screws instead of 3/8" lag screws for a roof remodel and they made the job very easy. Definitely worth every penny.

Same screw but lower price.

These #10 X 3-1/8" screws work really well - they don't easily split wood when you are close to the edge and have massive clamping force. The Torx drive doesn't slip and allows the large flat head to be buried into wood, even when the wood is old and dry. If you are working overhead the screws will not stay on your driver as well as Robertson design (square head for US readers) but this is a minor complaint.

These structural screws from Amazon are a terrific valve compared to the big box stores and of equal or better quality. If you have used lag screws in the past you will love switching to structural screws for both their simplicity and strength.

If you’ve never used these then you’re in for a eye opener. I used these to build my deck and the fact that you don’t need to pilot drill saves lots of time! I used these and everything in between up to their 6” ones. I really like them! Just wish they weren’t so expensive.The price is no better then my local hardware store.

These are good for heavy duty construction projects, like building large storage shelving etc.
