  • For your toughest fastening applications, use Grade 8 fasteners every time
  • Grade 8 Cap Screws comply with SAE J429, ANSI/ASME B18.2.1 hex cap screws

Rule of thumb to figure bolt thread length:

  • For bolts under 6": Twice the bolt diameter plus a 1/4"   
  • For bolts over 6": Twice the bolt diameter plus a 1/2"    
  • This gives you the approximate bolt thread length available
