Premium Quality Bolts in Bahrain – ASTM A193, A320 L7, A307, SS 304, 316, Duplex, High Tensile Fasteners

All India Steel Engg. is a prominent exporter of high-quality bolts that are meant to satisfy the various needs of industrial industries across the globe. Bolts are necessary mechanical fixings to have two or more parts connected in a secure manner, which is stable structurally and can carry the weight. They are commonly used in building work, oil and gas, shipbuilding, power stations, the car industry, and heavy engineering. Being a reliable bolt supplier in Bahrain, the company aims at providing precision-engineered fastening solutions that meet the international standards and project requirements.


There are different types of bolts: hex bolts, heavy hex, anchor, carriage, eye, and stud bolts, which are used in a particular application. These fasteners are produced using various materials such as carbon steel, stainless steel, alloy steel and duplex steel to meet the different environmental and loading conditions. The focus is laid on dimensional precision, high tensile strength, corrosion resistance and long service life as a dependable fastener supplier. Modernised production methods and quality checks lead to a steady performance in challenging industrial conditions.


  • ASTM A193 B7 – High-strength alloy steel bolts commonly used in high-temperature and high-pressure applications.
  • ASTM A320 L7 – Designed for low-temperature service with excellent toughness and strength.
  • ASTM A307 – Carbon steel bolts suitable for general-purpose applications.
  • ASTM A325 – High-strength structural bolts widely used in construction and heavy engineering projects.
  • SS 304 – Stainless steel grade offering good corrosion resistance and durability.
  • SS 316 – Enhanced corrosion resistance, especially in chloride and marine environments.
  • SS 316L – Low carbon version of 316 with improved weldability and resistance to intergranular corrosion.
  • UNS S31803 (Duplex Steel) – Superior strength and excellent resistance to stress corrosion cracking.
  • Property Class 8.8 – Medium carbon steel bolts suitable for structural applications.
  • Property Class 10.9 – High tensile bolts used in heavy-duty mechanical assemblies.
  • Property Class 12.9 – Very high-strength bolts for critical load-bearing applications.


Having high representation in international B2B business, bolts are available in customised sizes, threads, coatings and finishes like hot-dip galvanised, PTFE-coated, black oxide and zinc-plated. The large-scale infrastructure and industrial projects are assisted by bulk supply capacity, competitive pricing, and timely logistics. The company serves contractors, EPC companies, and distributors, in which case the emphasis is on quality consistency, reliable documentation, and compliance with international standards of fasteners.
