No pilot needs to be drilled and saved time. Holds TV wall mount very securely

Strong and exactly as described.

I wouldn’t use anything else to hang cabinets. These are the best your going to get.

Yes! As advertised they penetrated the wood at the precise chosen point cutting its pathway to the correct depth! How pleasurable to screw!

Can never find these in the hardware stores, but them here and get what you want. Really strong, but pricey.

I'm using this particular fastener to attach two-by-six ceiling joists to roof rafters in an attached garage I'm reframing, and decided these were the perfect length so as not to protrude, while providing exceptional holding power.

They hold well! Not that expensive for the amount of hold they provide.

Strong and easy to use

They are not cheap, but you get what you pay for. I built my second story deck exclusively with GRK structural and framing screws. I enjoy helping family and friends building their outdoor projects but under one condition: If you're using GRK screws? I will help you for free!!! Use any other screws and I will charge for my labor. GRK screws will not slip, saving you time and no headaches.
