Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, leading to material deformation or fracture.Use a torque wrench to adhere to recommended torque specifications for polycarbonate fasteners, or hand-tighten until snug and then apply a small additional turn.
Using a metal hex driver that could scratch or damage the polycarbonate head.Employ a hex driver with a plastic or coated tip, or ensure the metal driver is clean and used with care to prevent cosmetic damage.

Common Applications
