| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an undersized wrench, leading to head stripping. | Always use a wrench that precisely fits the 23mm hex head to prevent damage and ensure proper torque application. |
| Over-tightening, which can compromise the integrity of the mating material or the screw itself. | Adhere to the recommended torque specifications for the application and materials to avoid over-stressing the fastening. |
| Using standard steel fasteners in corrosive environments, leading to premature failure. | Utilize the 304 stainless steel variant for its inherent corrosion resistance, especially in humid, saline, or chemically aggressive settings. |
