United StatesBetter than the originals
I have built numerous historical (replicas) wood project for many years using traditional wood working tools and was always on the lookout for affordable square headed bolts and lags. Old West has them at affordable prices and almost limitless size selections. They are exactly the same as the originals manufactured up to WW ll. As an additional plus, staff was exceptionally helpful during my phone order and it was a pleasure to speak with a human who knew the product line. Many Thanks from a new lifetime customer.
