About M14×1.5 fine pitch bolts

Automotive, precision machinery.

Fine pitch threads (1.5 mm) have more threads per unit length than coarse threads. This provides:

  • Better resistance to vibration loosening
  • Finer adjustment capability
  • Higher tensile stress area (stronger)
  • More susceptible to galling and thread damage

Common applications include automotive engines, aerospace, and precision machinery where vibration resistance is critical.
