Grade 10.9 Anchor Bolts & 10.9 Grade Bolt Manufacturers In India

Hsfg Bolts Grade 10.9 belong to the ASTM A324 specification. These are intended for high stress applications because they have high tensile strengths. Suraj Metal Corporation is a leading manufacturer of the different bolts from the Grade 10.9 Bolt Material which has high tensile strength. The bolts can be in different sizes ranging from M20 to M100. There are different finishes to the Grade 10.9 Screw and other types of fasteners can come with different finishes as well.

The hot dip galvanized, zinc plated or plain types of finishes are available for the Grade 10.9 Nuts and other fasteners. The difference between the Class 10.9 Bolt and the grade 8 fasteners is that that grade 10.9 has more toughness. The toughness makes it useful in motorized applications where high power and stress are applied. The chromium based low carbon steel used to make the Grade 10.9 Steel Bolts makes them more corrosion resistant as well. The fasteners have 940MPa minimum yield strength and 1040MPa minimum tensile strength. As a leading supplier, we have all different types of Grade 10.9 Stainless Steel Bolt in different sizes as well. Please contact us for a complete price list and the different types of fasteners such as the Hex Bolt Class 10.9 in this same grade.
