Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-torquing the screw, leading to thread stripping or material fatigue.Always use a calibrated torque wrench and adhere to the recommended torque specifications for the fastener and mating material.
Using the wrong thread pitch or diameter for the application.Verify the thread specifications of both the screw and the receiving component to ensure proper compatibility and secure engagement.

Common Applications

  • Aerospace structural components
  • High-performance marine hardware
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Titanium Grade 5 can gall if not properly lubricated or if subjected to excessive friction during installation.
  • Ensure compatibility with mating materials, as certain dissimilar metals can lead to galvanic corrosion if not properly addressed.
