Standards, and Grades
Bolt Grades and Standards
We manufacture bolts in compliance with these international standards:
• ASTM, AISI, SAE, ISO, DIN, JIS
Metric Bolt Grades:
• 4.8, 5.8, 6.8: General-purpose to medium-strength applications.
• 8.8, 10.9, 12.9: High-tensile grades for demanding industrial applications.
SAE Bolt Grades:
• Grade 2, 5, 8: For general use, automotive, and heavy-duty applications.
Stainless Steel Bolt Grades:
• A2-70, A2-80: General corrosion resistance.
• A4-70, A4-80: Superior resistance for marine and highly corrosive environments
Raw Material Wire Rod Grades
Carbon and Alloy Steel:
• 10B21, 10B33: Boron steel for high-strength fasteners.
• SWRCH35K, SWRCH22A: Carbon steel for general applications.
• SCM435, 40Cr: Alloy steel for high-stress environments.
• Q195, 1018: Low carbon steel for lower-strength applications.
Stainless Steel:
• 304, 304L: General corrosion resistance.
• 316, 316L: Marine-grade for chloride-rich environments.
• 321: High-temperature resistant.
• 410, 430: Heat and corrosion-resistant for industrial use.
