The water industry has become one of the fastest-growing sectors for specialist fastener exports, driven by global demand for robust, corrosion-resistant bolting solutions. From desalination plants to sludge treatment facilities, Hague Fasteners supplies precision-engineered fasteners that meet the most demanding specifications.

Our components are trusted by international water reuse companies and UK institutions including the Environment Agency and British Waterways, thanks to our expertise in manufacturing bespoke fasteners in Duplex, Super Duplex, and high-performance nickel alloys. Whether you’re sourcing engineer studs for reverse osmosis systems or corrosion-resistant socket cap screws for filtration equipment, Hague Fasteners delivers certified, project-specific solutions with full traceability and rapid turnaround.

Engineered for Harsh Conditions

Water treatment environments demand exceptional material integrity. Therefore, we manufacture in all grades of:

• Duplex and Super Duplex stainless steels (UNS S31803, S32760, S32750)
• 300 series stainless steels
• Nickel alloys such as Inconel 625, Monel 400, and Hastelloy C276

These materials offer superior resistance to pitting, crevice corrosion, and chloride-induced stress cracking—critical for reverse osmosis plants, purification systems, and filtration equipment.

Bolting Solutions for Every Application

Our specialist fasteners are designed to perform under pressure, with precision threading and dimensional accuracy. We supply:

• Engineer Studs and Waisted Stud bolts for high-integrity flange connections
• Hex Bolts, Bi-Hex Bolts, and Heavy Hex Nuts for pump and valve assemblies
• Allthread Studding for structural anchoring in treatment tanks
• Locking solutions including Nyloc Nuts, All metal Lock Nuts, Quadlock and Trilock Nuts for vibration resistance
• Socket Capscrews, Low Head Socket Capscrews, and Torx Drive Fasteners for compact, high-torque installations
• Slotted Countersunk Screws and Pozi Pan Head Screws for panel and enclosure applications

Serving Ancillary Water Sectors

Moreover, we support a wide range of water-related industries, including:

• Water Treatment and Sludge Treatment Plants
• Filtration and Purification System Manufacturers
• Desalination and Reverse Osmosis Installations
• Water Utility Companies and Infrastructure Contractors

Material Versatility

Beyond stainless and nickel alloys, we offer fasteners in:

• Copper, Naval Brass, and Brass CZ121
• Silicon Bronze UNS C65500 and Phosphor Bronze
• Aluminium, Aluminium Bronze CA104, NES833, and C63000
• Incoloy 800H/HT, Inconel 718, 825, and 904L

These materials are ideal for non-sparking, marine-grade, and low-conductivity applications.
