Review on High-Quality Prime Line 9035185 Screw - Phillips Solid: A Reliable Choice! by Mark Dahmer

Probably suitable for light softwood work. They might be suitable for hardwood if each individual screw hole was pre-punched prior to screw insertion. I pre-drilled a hole larger than the bolt shank and most bolts still broke between the top of the threads and the base of the bolt. head, so I had to switch to steel screws. I don't know if they're poorly made or if they're just not designed for anything other than easy thread holes.
