A: Hi, I am Andrew from GRK. Based on calculated estimates from other GRK products, we have recommended that 540 screws could cover upwards of 150 square feet and 1080 screws could cover upwards of 400 square feet.
A: The GRK screws have heads ideal for wood but probably not ideal for metal plates. The Simpson screws have heads that align with the plates and are a much better choice than wood screws. The Simpson screws have threads along much of their shank - about the same amount of threads as the GRK screws.
A: Hi, I'm Andrew from GRK. No, GRK R4 products are not meant to penetrate steel studs. For wood-to-steel fastenings, we recommend you review the TEKS product line.
