Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the aluminum screw, which can lead to thread stripping or galling due to the relatively softer nature of aluminum compared to steel.Always use a calibrated torque wrench and adhere to the specified torque values for the material and thread size. Avoid excessive force.
Using inappropriate tools that can damage the hex head, such as worn or ill-fitting wrenches.Employ high-quality, properly sized hex wrenches or sockets to ensure full contact and prevent slippage and damage to the fastener head.

Common Applications

  • Lightweight structural assemblies
  • Corrosion-sensitive environments
  • Aerospace and automotive components

⚠️ Engineering Warnings

  • Aluminum 6061 has lower tensile strength and hardness compared to steel fasteners; select appropriate torque values to prevent damage.
  • Ensure compatibility with mating materials, especially in dissimilar metal applications, to mitigate galvanic corrosion risks.
