These fasteners provide excellent corrosion resistance, mechanical strength and durability over time. Subsea Fasteners are intended for critical service conditions and used in highly pressured subsea equipment where reliability is very important.

Our Subsea Bolting 20E products are available in various thicknesses and finishes to fit specific operational requirements. We provide diameters ranging from 1/4” to 4” and M6 to M120 that can be installed in flexible configurations. Our coating options include SermaGard, Xylan and Moly with special finishes such as silver plating and electroless nickel for extra protection. Available in various types including Hot Formed Bolts, Hot Formed Nuts and Machined Stud Bolts and Nuts. The subsea bolting 20E material offers impressive tensile strength, excellent performance in extreme conditions and good thread quality to meet high-risk application needs.

Subsea Bolting 20E is utilized in a wide variety of industries in which safety, strength and longevity of the fastener are paramount. It is used in the oil and gas industries, where API-compliant fasteners provide assurance that subsea drilling equipment will perform reliably. In the mining and construction industries, it is commonly used for the toughness and durability of the fasteners. Other important industries include power plants, refineries, sugar mills and marine, where durability and dependability are critical in adverse conditions. In shipbuilding, Subsea Bolt Tensioners are used to facilitate secure assembly of fasteners subjected to extreme stress and vibration.

Every Subsea Bolting 20E product undergoes quality checks for compliance to national and international standards. The API bolting standards enhance Subsea Bolting and its products with well defined bolting specification levels which are BSL1, BSL2 and BSL 3. Each bolting specification is classified based on testing and documentation that the product is subjected to. For external threaded bolting like studs, bolts and screw grades include ASTM A193 Grade B7, B7M and ASTM A320 Grade L7, L7M, L43. Internal threaded bolting like nuts include grades ASTM A194 Grade 2H, 2HM, 7, 7M and 43. By following these standards we ensure that every fastener provides reliable performance in extreme subsea conditions.
