Grade 8.8 Bolts

Class 8.8 Nuts, High Tensile Class 8.8 Studs Manufacturer in India

Grade 8.8 Bolts belong to the DIN 933 grade 8.8 standard. This is a structural grade for bolts. This is a medium carbon steel bolt specification. These bolts are heat treated by quenched and tempered methods. Navstar Steel is a leading manufacturer and supplier of the Grade 8.8 Bolts in different types.

Call us to know more about Ready stock of BS 3692 Grade 8.8 Hex Bolt, M20 Grade 8.8 Galvanised Bolts, ASME SA324 8.8 Stainless Steel Bolts

These are suitable for low tensile strength applications as the medium carbon material has low tensile strength. But the medium carbon content makes the Class 8.8 Nuts to have high ductility and workability. The High Tensile Class 8.8 Studs are metallic rods with threads on both ends. The threads on the studs are male and they connect to the equally sized female threaded components on both ends of the stud.


The BS 3692 Grade 8.8 Hex Bolt and others in the 8.8 grade come with different lengths ranging from 20mm to 100mm and different finishes. There could be zinc plated, hot dip galvanized or plain types of bolts. The M20 Grade 8.8 Galvanised Bolts are dipped into the galvanizing solution and get a galvanized coating. The products are used in a variety of industrial applications ranging from domestic, commercial to industrial applications. The ASME SA324 8.8 Stainless Steel Bolts are cost effective, long lasting and ductile bolts. They are suitable for low strength applications with low corrosion risks. Please contact us for more information on the products and pricing.
