Grade 8 bolt hardness– material equivalentNov 29, 2017 · Grade 8 are in the 175 ksi range. A common pre heat treat 4130 is ETD 150. It is chemically relatively unspecified, but produced to 150 ksi strength. There also used to be an ETD 175, produced to 175 ksi tensile strength. I haven't used any in a long time, so I don't know about any current availability. The ETD 175 will be much closer to grade 8 bolts.What steel are grade 8 nut and bolts made off?Feb 23, 2018Grade 8 Specs - Practical MachinistJul 10, 2007See more results
