Subsea Control Module Fastener joints experience constant compressive stress from hydrostatic pressures exceeding 1,000 bar in deepwater fields. This long-term pressure exposure leads to material creep and joint relaxation. To counteract this, Subsea Control Module Fastener materials are selected based on long-duration yield retention, using precipitation-hardened alloys such as Inconel 718 with documented behavior under ASME VIII Div 2 and ISO 13628-1 loading conditions.
Exposure to chloride ions, hydrogen sulfide, and microbial agents in subsea conditions makes localized corrosion a principal design concern for any Subsea Control Module Fastener. To address this, fasteners are fabricated from corrosion-resistant alloys like Super Duplex UNS S32760, Nitronic 60, or Alloy 625, with surface conditioning that meets NACE MR0175 and ISO 15156 requirements. Crevice geometry is reduced through optimized thread root design, with full heat lot traceability and corrosion testing per ASTM G48 Method A.
Subsea Control Module Fastener engagement affects not only mechanical clamping but also alignment of internal hydraulic and electrical conduits. Thread concentricity, pitch tolerance, and fastener straightness are tightly controlled within ISO 965-4 Class 5e6e or tighter, to prevent flange misalignment and port sealing failure. Every Subsea Control Module Fastener is machined with coordinate metrology verification to ensure interface fidelity with standardized SCM bolt hole arrays, preserving sealing integrity and ensuring proper torque transmission to O-ring loaded interfaces.

Secures hydraulic and electrical interfaces within vertical or horizontal trees, ensuring joint integrity under extreme hydrostatic and axial loads.
Maintains structural connection of valve and sensor housings, preventing preload loss due to pressure cycling and thermal gradients.
Fastens internal components within SDUs, providing stable support for routing hydraulic lines and electrical harnesses across seabed infrastructure.
Supports mechanical joints in UTAs, ensuring corrosion-resistant clamping in high-pressure, high-salinity deepwater environments.
Joins electronic and hydraulic compartments, maintaining enclosure sealing and torque retention during ROV installation and retrieval operations.
Provides secure anchoring of SCM interfaces to pipeline hardware, accommodating bending stresses and local thermal expansion effects.
Subsea Control Module Fastener interfaces are designed for secure engagement with ROV and diver tools, using non-slip hex, bi-hex, or spline drives that resist biofouling and marine growth. Surface hardness is optimized to prevent drive wear, while torque-tension behavior is validated per ISO 16047 and DNV-RP-C203 to ensure accurate preload in subsea conditions.
Subsea Control Module Fastener materials are selected for low hydrogen diffusivity and tempered post-machining to prevent embrittlement in cathodic zones. Hardness is controlled below 35 HRC, and SSRT testing in seawater confirms resistance to hydrogen-induced cracking near galvanic systems.

Frigate uses CNC machining with in-process metrology to achieve sub-50 micron tolerance levels. Thread concentricity and perpendicularity are verified using coordinate measuring machines (CMM). This prevents misalignment between hydraulic ports and sealing faces in SCM housings. All fasteners are qualified against ISO 2768 and ISO 965 thread standards.
Frigate conducts ASTM G48 Method A and NORSOK M-650 corrosion tests on all fastener batches. Materials are sourced with 3.1 certificates and verified for PREN > 40 for chloride resistance. Post-machining passivation and electrochemical testing confirm protection against crevice and pitting corrosion. This ensures long-term integrity in H₂S and chloride-rich zones.
Fasteners are subjected to tensile, proof load, and stress rupture testing as per ASTM A193 and API 20E/20F where applicable. Finite element simulations validate stress behavior under bolt-up loads and external hydrostatic pressure. Mechanical properties are cross-checked with heat treatment charts and hardness profiles. Frigate maintains full lot traceability for mechanical verification.
Frigate uses galling-resistant alloys like Nitronic 60 and applies solid film lubricants where applicable. Surface finishes are held within Ra 0.8–1.6 μm to balance friction and preload reliability. Thread rolling or cold working is applied selectively to increase fatigue strength. Lubricated torque-tension tests validate smooth assembly under ROV tool conditions.
Frigate selects materials with low hydrogen uptake and controls fastener hardness below 35 HRC to meet NACE MR0175. Post-machining thermal treatment removes residual stresses that can attract hydrogen absorption. SSRT testing in simulated cathodic environments ensures embrittlement resistance. This guarantees safe performance near galvanic systems like anodes and ICCP setups.
