fevicon-logoBenefits of ASTM A193 Grade B8M Class 2 Stud Bolts

Our fasteners are strong and resistant to rust, so they are reliable even in tough conditions.  Each feature gives the user a clear benefit:

  • Corrosion Resistance- 316 stainless steel with molybdenum prevents pitting, crevice attack, and general corrosion, even in saltwater.
  • High Strength- B8M Class 2 studs are strain-hardened for superior tensile and yield strength. It performs well under pressure.
  • Temperature Resistance- These bolts hold their strength in both high-heat and cryogenic conditions.
  • Chemical Resistance- It resists acids, alkalis, and solvents found in chemical and petrochemical plants.
  • Wear & Galling Resistance- The austenitic stainless structure reduces galling during tightening and reuse, ensuring longer thread life.
  • Dimensional Accuracy- Tight tolerances and consistent threading guarantee a perfect fit during assembly.
  • Aesthetic & Surface Finish- Its polished finish improves appearance and reduces the risk of surface contamination.
  • Long Service Life- High strength and corrosion resistance work together for reliable, low-maintenance performance.

Because of these benefits B8M Class 2 studs and A193 Gr B8M Cl 2 studs are perfect for important industrial fastening applications where failure is not an option.
