Sold in sets of 50

• Have a larger pitch (fewer threads per axial distance) compared to fine threads.
  
• Are specified for most applications unless there is an overriding reason to use a fine threaded bolt.
  
• Are beneficial because they are less likely to cross thread, more tolerant in adverse conditions and facilitate quick assembly.
  
• Are used when threaded into aluminum or cast iron because the finer threads tend to strip more easily in these materials.
  
• Are stronger when assembled with lower strength nut or tapped hole materials.
