Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the titanium screw, which can lead to thread stripping or fastener failure.Always use a calibrated torque wrench and adhere to the recommended torque specifications for the material and thread size.
Using incompatible tools or damaging the hex head during installation.Use high-quality, correctly sized tools that fit snugly into the hex socket to prevent cam-out and damage.

Common Applications

  • Aerospace structural components
  • Marine hardware and fittings
  • Medical implants and equipment
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Titanium Grade 5 has a lower elasticity than steel; ensure appropriate clamping force is achieved without excessive deformation.
  • Avoid using abrasive cleaners or harsh chemicals that could potentially degrade the titanium surface over time.
