Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-torquing the aluminum screw, which can lead to thread stripping or material deformation.Utilize a calibrated torque wrench and adhere strictly to the specified torque values for Aluminum 6061 fasteners.
Using steel washers with aluminum screws, which can cause galvanic corrosion.Employ washers made from compatible materials, such as aluminum, nylon, or specifically designed anti-corrosion washers.

Common Applications

  • Structural components in lightweight machinery
  • Marine and nautical equipment assemblies
  • Aerospace interior fittings and fixtures

⚠️ Engineering Warnings

  • Do not exceed the maximum recommended torque for Aluminum 6061 to prevent thread damage.
  • Avoid direct contact with dissimilar metals in corrosive environments without appropriate isolation measures to prevent galvanic corrosion.
