MS Hex Bolts Grade 4.6, 8.8, and 10.9 are high-demand mild steel fasteners designed for secure, reliable joining in industrial, construction, fabrication, and infrastructure applications. Available in metric sizes from M6 to M30, these hex bolts are supplied in full thread and partial thread options to suit different load-bearing and assembly requirements. The product is manufactured to ISO standard specifications, making it suitable for buyers who need consistent quality, dimensional accuracy, and export-ready fastener supply. These mild steel hex bolts are offered in three practical surface finishes: zinc plated for improved corrosion resistance, hot-dip galvanised (HDG) for enhanced outdoor durability, and plain finish for applications where coating is not required or will be applied later. The availability of multiple strength grades—4.6, 8.8, and 10.9—allows buyers to source the right bolt for light-duty, medium-duty, or high-strength fastening needs. The hex head design enables easy installation using standard tools, while the broad size range from M6 to M30 makes these bolts suitable for machinery, structural assemblies, heavy equipment, steel fabrication, and general industrial fastening. As one of the most exported fastener products from India, these MS hex bolts are a dependable bulk procurement choice for distributors, wholesalers, and industrial supply buyers looking for factory-direct sourcing through The Sunrise Group. For B2B buyers searching for mild steel hex bolts, metric hex bolts, ISO hex head bolts, HDG hex bolts, zinc plated hex bolts, and Grade 8.8 or 10.9 fastening solutions, this product offers a versatile and export-ready option with multiple specifications under one listing.

These grades indicate different tensile strength levels. Grade 4.6 is suitable for light-duty applications, Grade 8.8 is used for medium to high-strength fastening, and Grade 10.9 is selected where higher mechanical strength is required.
For outdoor or corrosion-prone environments, hot-dip galvanised (HDG) hex bolts are generally preferred because they provide stronger corrosion protection than plain or standard zinc plated options.
Yes, this product is available in both full thread and partial thread versions, allowing buyers to choose based on the required clamping length and structural application.
