Perfect for Kreg Jig Projects
These 4" Kreg screws did exactly what I needed them to on my fence project. The flat head design is ideal for pocket holes (think flat like bolt heads), no splitting like you’d get with regular cone-head screws. They went in clean, held strong, and worked great for my project. I bought a little more than I needed just to be safe, and honestly, I’d buy them again without hesitation.

Works great with the XL pocket hole kit from Kreg
These hold tight, wont split the wood and work amazing. Best outdoor pocket screws on the market IMO.

Best pocket hole system on the planet.
Have yet to find a better pocket hole system than Kreg. The screws have a great protective coating and the head hasn't stripped once. I got the big box so I always have some on hand.

GLAD I BOUGHT IT
Great tool for doing securing wall studs and other forms carpentry. The drill bit is extremely well-made and very sharp, almost like a knife edge...cuts thru wood like a hot knife thru warm butter.

Absolute beast hardware
These things are absolute beasts! I’m glad I discovered them. I’m using them to construct my heavy duty fence outside and they’re great. Constructed a several hundred pound giant picnic table with them as well and holding rock solid still.

Great screws for securing 4x4’s
Great screws, but a bit spendy. Would have been 5 stars if a bit cheaper.

Habe die Schrauben schon mehrfach verwendet, sind 100%-ig. Alle Verbindungen damit sind sehr stabil (und wieder problemlos lösbar).

As far as the screws are concerned, they are exactly as expected, no issues. The box of screws was shipped in the bubble/envelope, and through shipping, the lid of the box came loose, and the screws were loose in the shipping material. Thankfully this wasn't an issue so much as an annoyance, as I just placed the screws back in the box and could close it.
