A local company in my area has 8620 bolts that are made in their shop for a pretty good price.
They are a very reputable company in my area and have some good quality parts.
Their bolts are made from 8620 steel instead of 158 Carpenters. Any benefits to a 8620 bolt over a 158?
They are MP tested but not HP. Thinking about getting a spare bolt, most likely will be a BCM, but just wanted to know thoughts on the difference in materials used.
