GRK772691121370 Fasteners-96025 RSS-185 10 by 3-1/8-Inch Structural, 50 Screws per Package-772691121370, Gold, 50 Count

Great item to secure some pt boards.

Making a junior (low) loft 4 ft high we have low ceilings. 8x8 feet wide and long. Used these screws for framing as I have back and neck problems and it’s easier to use the drill than hammering into thick wood. No need to drill pilot holes if you go slow at first.

I used these to attach my kitchen cabinet counter support brackets. I feel confident that these will hold my very expensive granite counter.

I love all GRK screws. It is my go-to screw for a variety of applications. I use these to drive 2x4 into 4x4 treated post. They are structural, so I consider these beefy enough for my needs. The washer head provides a more stable attachment.

I use GRK screws when I can (that is, when they are right for the application and the size I need is available). They are hardened so they will not twist apart under torque that and the heads will not cam out (and then strip out) like some other screws will (even with Torx heads). They are not indestructible, but they do seem stronger than Swan Secure, GripRite and other brands I have tried. It works as designed to drill _closer_ to an edge without splitting wood than other screws (as designed), but it has it's limitations.The down side is that they are more expensive than other screws, and they don't always offer the specific size I would like, but they make up for that many times over by the frustration they have saved me by not breaking or stripping out.

Well Worth the few extra $.

I have no idea of the 'structural' strength of these things as i'm not sure what test would actually prove it's strength. But in the field, it seems to be a very well made and easy to use fastener. I have driven roughly 50-60 of the 3 1/8" so far and not one has even hinted at wanting to strip out the head. They drive very easily in pressure treated 2 or 4x..Because of their composition (hardened steel), they have the strength of a nail, along with the usefulness of a screw. You can't say that about ceramic coated exterior screws which will simply snap in half under the right conditions.

A bit pricey but I got them fast. Their a great quality. Most installers use plan wood screws which are not recommended by Simonton. These screws are designed for vinyl windows.

When I need the best fasteners without any second guessing on quality: GRK’s are the first choice. I’ve installed literally over ten thousand of various GRK screws, with many of them being the RSS and the cabinet style fasteners. I use size ranging from 1-1/2” to 3-1/8” cabinet style, medium size #8s, #9’s and #10 deck-style, 2-1/2” to 12” structural screws. Always pleased. Comes at a premium on first cost. Saves me time and heartache with no second guessing on strength of hold and ease of application. Cry once. Never cry again.When appropriate (price or availability), I also use WoodPro and PowerPro screws as closeseconds. They have similar qualities, although are not always less expensive.
