This 1-1/2" coarse thread, #2 square drive washer head screw works well in 1" thick, softer material. The washer head of this screw is our most popular head style as the wide bearing surface of the head will not overdrive in the bottom of the pocket. This is especially important in softer material such as plywoods and composites. The screw also features a type 17 auger tip that self-taps its' own hole, eliminating the need to predrill in even the hardest materials. Kreg screws also have larger diameter steel shanks than many other screws on the market today making for an impressively strong screw that is almost impossible to break. Our screws have a zinc finish and a dry-lubricant coating that eases driving torque and provides greater rust resistance. For maximum rust resistance, look to our Sun-Seal coated weather resistant screws.

I will be using the screws to attach my vinyl siding to the house and garage so I decided to put these screws to the test to see if they would rust. Test period 1-1/2 months: I placed two Kreg screws in a bucket along with old screws, nails , rocks, dirt and dirty water for 1-1/2 months in my driveway. Result: only 1 of the 2 Kreg screws had a small rust spot on the smooth part of its shaft but the head and threaded areas were slightly tarnished but Rust Free. Not bad for an indoor use screw. I 'm totally convinced that I could use these screws to attach my vinyl siding to the house and garage.
