Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive torque, which can strip threads or deform the fastener in aluminum.Consult torque charts specific to M8 fasteners in Aluminum 6061 and utilize a calibrated torque wrench.
Cross-threading the fastener, leading to damaged threads on both the screw and the mating component.Start threading by hand to ensure proper alignment before applying any tools.

Common Applications
