What is Moisture Impact on HSFG Bolts: Grades 10.9 vs 12.9 about?

The document compares the effects of moisture on High Strength Friction Grip (HSFG) bolts of Grade 10.9 and Grade 12.9, highlighting that Grade 12.9 is more susceptible to corrosion, hydrogen embrittlement, and stress corrosion cracking. Recommendations include avoiding moisture contact, using appropriate coatings, and ensuring clean surfaces to maintain performance. Overall, Grade 10.9 is preferred for outdoor use unless Grade 12.9 is necessary and adequately protected.
