Fasteners for Critical Industries Across the GCC & Beyond
From oil & gas wellheads to offshore platforms, petrochemical reactors to high-rise construction — Asia Bolts Industries LLC manufactures certified fasteners engineered for the precise demands of each industry we serve. Every fastener leaves our Dubai facility with full material traceability, mill certification and a Material Test Report.
Industries We Serve
Every industry has unique fastener requirements — different standards, materials, coatings and certifications. We manufacture to your specification, not a generic catalogue.
Oil & Gas
Upstream, midstream & downstream — wellheads, pipelines, flanges & pressure vessels
Oil and gas operations demand fasteners that perform without failure under extreme combinations of pressure, temperature and corrosive media. Asia Bolts Industries manufactures high-strength alloy steel stud bolts and heavy hex nuts to ASTM A193 and A194 specifications — the globally recognised standard for flanged joint bolting in wellheads, Christmas trees, pipelines and pressure vessels. For sour service environments containing H2S, we supply NACE MR0175 / ISO 15156 compliant B7M and 2HM grades with controlled hardness to prevent sulphide stress cracking. All oil & gas fasteners are supplied with full MTR, heat number traceability and dimensional inspection reports. Third-party inspection by SGS, Bureau Veritas or Intertek is available on request for Aramco, ADNOC and Oman Refinery approved projects.
Key fastener grades supplied
ASTM A193 B7, ASTM A193 B7M (sour service), ASTM A193 B16, ASTM A320 L7 (low temp), ASTM A320 L7MSS316 / 316L, Duplex UNS S31803
Standards & approvals
ASTM A193 / A194, API Spec 20, ENACE MR0175 / ISO 15156, ASME B16.5, Saudi Aramco approved, ADNOC vendor
Petrochemical & Refinery
Reactors, heat exchangers, pressure vessels & high-temperature piping
Petrochemical and refinery environments expose fasteners to a combination of high temperatures, aggressive chemicals and cyclic thermal loading that few materials can withstand reliably. Asia Bolts Industries supplies alloy steel bolting to ASTM A193 B16 for service temperatures up to 650°C, duplex and super duplex stainless fasteners for chloride-rich and acidic process streams, and exotic nickel alloy fasteners — including Inconel 625, Hastelloy C-276 and Alloy 20 — for the most aggressive service conditions. Our fasteners for petrochemical service are manufactured with full chemical composition and mechanical property certification, PWHT (post-weld heat treatment) documentation where required, and hardness testing per NACE requirements for sour service applications.

Construction & Infrastructure
High-rise structures, bridges, cranes, industrial buildings & civil infrastructure across the GCC
The GCC’s construction boom demands structural fasteners that meet both international standards and regional project specifications. Asia Bolts Industries manufactures high-tensile structural bolts, anchor bolts, foundation bolts and threaded rods to ASTM A325, A490 and ISO 8.8 / 10.9 specifications, with hot-dip galvanizing to ISO 1461 for long-term corrosion protection in the Gulf’s humid coastal climate. Our in-house bending and forming capability produces J-bolts, L-bolts and U-bolts to custom embedment depths for concrete anchor applications. We hold stock of standard structural grades for fast dispatch across UAE, Saudi Arabia, Qatar, Oman, Kuwait and Bahrain — reducing project delays for time-critical construction programmes.

Power Generation
Gas turbines, steam boilers, heat recovery systems & transmission infrastructure
Power generation fasteners must maintain their mechanical properties through thousands of thermal cycles, extreme temperatures and high-pressure steam environments. Asia Bolts Industries manufactures high-temperature alloy steel bolting to ASTM A193 B16 — a chromium-molybdenum-vanadium grade maintaining strength to 650°C — alongside B7 for standard boiler and heat exchanger applications. For gas turbine casing bolting requiring elevated temperature creep resistance, we supply Inconel 718 fasteners. Our heat treatment facility, with AMS 2750-calibrated furnaces, ensures precise quench and temper operations with full heat treatment records accompanying every MTC. Stainless steel A193 B8 / B8M fasteners are supplied for pump casing, valve and superheater applications requiring oxidation resistance.

Water Treatment & Desalination
Desalination plants, pumping stations, water pipelines & treatment infrastructure
Desalination and water treatment plants in the GCC operate in some of the most corrosive environments imaginable — hot concentrated brine, chlorinated water and humid coastal conditions. Asia Bolts Industries supplies super duplex stainless steel fasteners with PREN values above 40 for Multi-Stage Flash (MSF) and Reverse Osmosis (RO) desalination plant bolting, where pitting and crevice corrosion failures can result in costly plant shutdowns. Titanium Grade 2 fasteners are available for the most aggressive high-temperature brine service. For water pipeline flanges and treatment plant civil structures, we supply hot-dip galvanized carbon steel and 316L stainless fasteners with dimensional compliance reports. We are an approved supplier to DEWA and Bapco Energies projects.

Steel Fabrication & General Manufacturing
Industrial equipment, warehouses, modular structures & machinery assembly
General industrial and manufacturing facilities across the GCC require consistent, competitively priced fasteners that meet dimensional and mechanical standards without the premium of exotic alloys. Asia Bolts Industries stocks the full range of carbon steel and stainless fasteners — from M6 to M160 — in standard and custom lengths, with same-week dispatch capability for urgent project requirements. Our in-house hot-dip galvanizing line eliminates third-party processing delays, and our CNC precision machining centre produces custom fastener profiles — T-bolts, eye bolts, lifting hooks and special shoulder bolts — to customer drawings with no minimum order quantity. ISO 9001:2015 quality management ensures every standard fastener is inspected to DIN and ISO dimensional tolerances before dispatch.

Marine & Offshore
Offshore platforms, FPSO vessels, marine pipelines & subsea structures
Marine and offshore environments present the most corrosive conditions that fasteners encounter — continuous seawater exposure, chloride-induced pitting, crevice corrosion at flange interfaces and cathodic protection interactions. Asia Bolts Industries supplies 316/316L stainless, duplex UNS S31803 and super duplex UNS S32750 fasteners with minimum PREN values of 35 and 42 respectively — ensuring resistance to pitting corrosion in seawater service. For subsea applications, our fasteners comply with API Spec 20F and IOGP S-725 corrosion-resistant bolting specifications. Hot-dip galvanized carbon steel fasteners to ISO 1461 with 85-micron zinc coating are supplied for above-waterline structural applications. All marine-grade fasteners include dimensional reports and coating thickness certification.
