Fasteners - General Stores, Hardware and Tools
Marine fasteners are bolts, nuts, screws, washers, studs, pins and related hardware used for ship construction, machinery installation, piping, outfitting and repairs. Selection depends on load, material compatibility, corrosion exposure, temperature and applicable class or project requirements.
ProShipWorks provides end-to-end support to source and supply Fasteners for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Common references include ISO 898-1 for carbon and alloy steel bolt mechanical properties, ISO 3506 for corrosion-resistant stainless steel fasteners, ISO 4014/4017 for hexagon bolts, ISO 4032 for hexagon nuts, ISO 7089/7090 for washers, and ISO metric thread standards. Project specifications may also require ASTM, ASME or EN compliance. |
|---|---|
| Class Approval | Class approval is not universal for general fasteners. DNV, ABS, Lloyd's Register, Bureau Veritas and ClassNK may approve or accept specific fastener materials, grades, manufacturers or bolted joints when required by vessel rules, drawings or equipment certification. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify size, thread, material, strength grade and coating before installation. Use compatible nuts and washers, clean mating surfaces, apply the specified lubricant or locking method, and tighten to the approved torque or tension. Do not mix incompatible stainless and carbon-steel components in corrosive service without suitable isolation. |
|---|---|
| Maintenance Tips | Inspect for corrosion, looseness, thread damage, cracking and coating deterioration during planned maintenance. Check critical bolted joints for torque or preload as required by the equipment maker. Replace fasteners showing deformation, severe corrosion or damaged threads with identical or approved equivalents. |
| Safety Notes | Use the correct grade and tightening procedure for the joint. Do not substitute low-strength fasteners in structural, pressure, lifting or machinery applications. Wear eye and hand protection, control dropped-object risks, and follow lockout, isolation and hot-work procedures where applicable. |
