Stainless Bolt Industries is a prominent stainless steel fasteners manufacturer and Supplier in Dubai. We deliver a broad range of SS hex bolts, stainless steel nuts, and SS screws in the UAE. Our fasteners are completely manufactured using top grade SS 304 and SS 316 stainless steel. We assure that our fasteners provide durability, precision, and superior performance across various industries.
Dubai’s project mix is tough on fasteners. Construction sites near the coast deal with salt-laden air. Oil and gas installations demand materials that don’t corrode even under high pressure. Marine projects requires fasteners that hold up in seawater contact. That’s the reason why we stock both 304 and 316 grade. So buyers can match the grade to the environment, not simply just the price tag.
Whether you’re sourcing a small quantity for a maintenance job or placing a bulk order for a large infrastructure project, our dispatch process is built around UAE delivery guidelines. We do work with procurement teams, contractors, and trading houses in Dubai on a routine basis, so we understand what the market needs: correct specs, appropriate certificates, and no surprises on lead time.
SS Hex Bolts in Dubai
Stainless steel hex bolts are among the most widely used fasteners in Dubai’s industrial and construction units. We do supply them in two grades, i.e. Grade 304 and Grade 316 across a complete range of metric and inch sizes.
SS hex bolts in Dubai are commonly specified for petrochemical plant assembly, marine construction, HVAC duct mechanisms, facade cladding on high-rises, and general structural bolting. The grade 316 hex bolts, in particular, are highly preferred for any coastal or offshore uses in the UAE where chloride exposure is a concern.
Available Types:
- Fully threaded hex bolts
- Partially threaded hex bolts (hex cap screws)
- Heavy hex bolts for structural applications
Available Sizes: M6 to M100 | 1/4″ to 4″ in inch sizes
Standards: ASTM A193, DIN 933, DIN 931, ISO 4014, ISO 4017
SS Hex Nuts in Dubai
A bolt is only as good as the nut it pairs with. We do supply stainless steel hex nuts in matching 304 and 316 grades, so the buyers get a consistent material mixture throughout the joint.
In the Dubai’s market, stainless steel hex nuts are heavily utilised in pipework flanges, structural steel connections, marine superstructures, and process equipment. For high-temperature or high-pressure lines, we can supply heavy hex nuts certified to ASTM A194 on request.
Available Types:
- Standard hex nuts (DIN 934 / ISO 4032)
- Heavy hex nuts (ASTM A194)
- Coupling nuts (extension nuts)
- Nylon insert lock nuts (SS hex nyloc)
- Flange nuts
Sizes Available: M4 to M100 | 1/4″ to 4″
Standards: ASTM A194 2H & 8M, DIN 934, ISO 4032
SS Screws in Dubai
SS screws cover a broad range of fastening applications where bolts are impractical, such as thinner sections, enclosures, sheet metal work, and light structural assemblies. We stock a comprehensive range of stainless steel screws in SS 304 and SS 316 for the Dubai and UAE market.
SS screws in UAE projects are used heavily in HVAC ductwork, electrical panel boxes, modular construction, food-grade equipment, and external facade mechanism. Grade 316 self-tapping screws are a very common request for outdoor marine applications in Dubai where the proximity to saltwater makes lower grades unreliable over time.
Available Types:
- Self-tapping screws (pan head, countersunk, hex washer head)
- Machine screws (pan, CSK, round head Phillips and slotted)
- Hex head self-drilling screws (tek screws)
- Socket cap screws (Allen screws)
- Set screws (grub screws)
Available Sizes: M3 to M20 | #6 to 3/4″ in inch series
Standards: DIN 7981, DIN 965, DIN 912, ISO 1481

Applications of Stainless Steel Fasteners in Dubai
Dubai’s construction pace, its coastal geography, and the concentration of energy and industrial projects in the UAE create a consistent, specific demand for quality SS fasteners across several sectors.
- Construction and Infrastructure Dubai’s skyline is the most obvious example high-rises, mixed-use towers, metro expansions, and bridge works all consume large volumes of hex bolts and nuts. Grade 304 covers most structural and architectural fastening needs where the material isn’t exposed to seawater or aggressive chemicals.
- Oil and Gas From onshore pipelines in the broader UAE to offshore platform components, the oil and gas sector in Dubai and Abu Dhabi relies on certified fasteners primarily ASTM A193 B8M (316 grade) studs and bolts for flange connections at pressure and temperature.
- Marine and Coastal Projects Dubai’s marinas, waterfront developments, desalination plants, and dry dock facilities all demand Grade 316 as a baseline. SS 316 hex bolts and self-tapping screws are standard in anything that sees regular saltwater exposure or sits near the Arabian Gulf coast.
- HVAC and Electrical Dubai’s massive commercial and residential developments require large quantities of SS screws and light-duty fasteners for duct systems, panel boards, cable trays, and mechanical rooms. Self-tapping SS 304 screws cover most of this work.
- Food and Pharmaceutical Food processing units, commercial kitchens, and pharmaceutical plants in Dubai’s industrial zones use SS 316 fasteners where hygiene and chemical cleaning are routine the resistance to chloride-based sanitizer’s matters here.
- Modular and Prefabricated Construction The growth of modular construction in the UAE means factory-fabricated modules arrive on site with pre-installed fasteners. Suppliers are being asked for larger, pre-packed quantities in standard sizes which is exactly the kind of bulk supply we handle.
Why Dubai Buyers Source SS Fasteners from Stainless Bolt Industries
- Export-ready documentation: Mill test certificates, material test reports, and product certificates are standard with every order. Buyers in Dubai and across the UAE regularly ask for EN 10204 3.1 certificates, and we supply them.

Frequently Asked Questions
The main difference is molybdenum SS 316 has it, SS 304 doesn’t. That 2–3% molybdenum in 316 makes a real difference in resistance to chloride corrosion, which is what you get from salt air, seawater, and many industrial chemicals. For general indoor construction in Dubai, SS 304 holds up fine and costs less. Anything coastal, marine, or chemically exposed in the UAE go with SS 316. It’s not a big price jump, and the service life difference is significant.
SS 316 is the standard for marine applications in Dubai and across the UAE coast. The Arabian Gulf environment is a chloride-heavy, high-humidity exposure exactly what 316’s molybdenum content is designed to handle. For submerged or splash-zone applications (jetties, boat fittings, marine structures), some engineers specify SS 316L (low carbon variant) for even better corrosion performance at welds. We can supply 316L on request.
