Grade 8 Hex Cap Screws

  • Thread: Coarse
  • Finish: Yellow Zinc
  • With a tensile strength of 150,000 pounds per square inch, grade 8 hex cap screws are stronger than grade 5. 
  • This grade is heated similar to grade 5, but they are fully heat treated versus case hardened. 
  • Their strength makes them good candidates for tractor fabrication, suspension applications and other high demand fastening applications.
  • If you are looking for a larger size,  thread type, or finish, please give us a call or send us an email.
