Info
  • All dimensions in above table are in inches.
  • Marking of these screws is not mandatory.
  • Due to the unfavourable head geometry these fasteners have reduced loadability.
  • Attention: As the thread tolerance class for thread sizes up to and including 1 inch is 3A, plating can cause thread fit problems.
