I'll preface this review with the information that I'm a fan of the other Strong-Tie products we've purchased for this owner-build house project. We are currently building a steel frame residence (cold formed steel with metal studs ranging from 20 to 16 gauge).
Because of the open C channel design of the metal studs it is not possible, in most cases, to hold the screw at a perfect 90 degree angle. These self-drilling screws have a propensity to skate when held at even a small angle of attack - as little as 75 degrees.
Prior to ordering these Simpson Strong-Tie screws, we were using identical size Grabber self-drilling #10 x 3/4" screws that performed much better when coming into the work surface at an angle.
Had I known these Strong-Tie screws have this tendency to wander off from the intended target point, I would have stayed with the Grabber product. I now regret this purchase.
