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.
What is the difference between partial thread and full thread?
Partial thread (also called shoulder bolt or tap bolt) has an unthreaded shank for shear strength. Full thread (fully threaded cap screw) provides more clamping engagement. Standard cap screws above 6 inches long are typically partial thread.
