Great screws
Would RecommendI’ll be looking for these screws whenever I need more. They never strip out on me while using an impact driver and have pretty good shear strength.

Would RecommendThese worked great for building the base of my built in cabinets as well as securing them to the studs. The included drill bit was useful as I didn't have to search for the compatible bit in my supplies.

These screws grab and bite like a 10 foot croc!
Would RecommendI bought these to use on a lean to on my shed. The bite these screws had was impressive. Easy to start and drove in with ease. No splitting with any shot which is a first for me.
