Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, leading to thread stripping or component damage.Always use a calibrated torque wrench and adhere to recommended torque specifications for the specific application and materials being joined.
Using incompatible tooling that damages the hex head.Employ high-quality hex sockets or wrenches that precisely fit the M4 head size to prevent cam-out and ensure efficient torque transfer.

Common Applications

  • Aerospace structural components
  • Medical implants and devices
  • Marine hardware and offshore equipment

⚠️ Engineering Warnings

  • Titanium Grade 5 exhibits excellent strength but can gall under high pressure and low lubrication. Proper lubrication is recommended for installation.
  • Ensure compatibility with mating materials; avoid mixing with significantly dissimilar metals in corrosive environments without proper isolation to prevent galvanic corrosion.
