During my 33 years of Millwright work we had our nuts bolts and washers delivered by a big name outfit. The quality of those bolts changes so much over the years that when we were taking apart machinery if it was a thru bolt with a nut on it we where better off just grabbing a burning outfit and burning them off. The materials had gotten so cheap and the last breads were so crude that when we hit them with an impact they were not going to be reusable anyway. If you want to use cheap imported junk go right ahead but for me I with spend a little more per bolt to use a better quality imported by lt. Goodluck and I can tell you one good think about the cheap stuff. When they snap off they are easier to drill for the easy out. Lol 😂 And yes when our Engineers came out of College they thought perfect World senerio until we showed them we always didn’t work in the perfect world.
