When you can’t find what you need from the big box vendors
Needed these Grade 8 3/4” bolts for my DIY sheet metal roller, since the commonly available versions from big box stores are not hard enough to withstand the constant compression of the nut against the bolt’s threads, making them distorted, which jammed up the tightening, requiring removal/disposal. Now these Grade 8 bolts, while not widely available, really hold up to such chronic abuse. Glad I now have a source for more robust hardware for my shop equipment.
