Frequently Asked Questions
What is the difference between Grade 5 and Grade 8?
Grade 5 (medium carbon steel, 120 ksi tensile strength) is suitable for most industrial applications. Grade 8 (alloy steel, 150 ksi tensile strength) is used for high-strength applications like automotive suspension and machinery. Grade 5 hex heads have 3 radial lines; Grade 8 has 6 radial lines.
Why does a carriage bolt have a square neck?
The square neck beneath the round head wedges into the wood as the nut is tightened, preventing the bolt from rotating. This allows tightening from one side only — perfect for deck and fence construction where you can not access the back side of the bolt.
