Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a standard steel screw in corrosive environments, leading to premature rust and failure.Always select 304 stainless steel fasteners for applications exposed to moisture, chemicals, or saltwater to ensure longevity and structural integrity.
Over-tightening the screw, which can strip threads or compromise the material's integrity.Refer to torque charts and use a calibrated torque wrench to apply the correct tightening force, preventing damage to the screw and mating components.

Common Applications
