About M16×1.5 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.
