U-bracket for WD bars ... issue with self tapping screws

Those self-tapping/self threading bolts are the devil. Seems to be the way of the world with fasteners these days. I see many different fasteners in different products and most of them are so soft that any extra force tears them up instantly. I assume that these soft-body fasteners are imported from overseas but I don't give US mfgs any more respect than what they deserve, either.
