1. Typical Applications in Shipbuilding Industry (Specific Products)

 

1.1 Hull Structure & Deck System

 
  • Marine Flat-head Eye Bolts with Hole
     
    Application: Connection of deck railings, hatch covers, ladders, bollards, ventilators and other movable/detachable structures.
     
    Characteristics: Flat head with center hole, suitable for split-pin or wire locking; resistant to severe vibration during navigation.
     
    Material: 316L stainless steel, duplex stainless steel, titanium alloy, resistant to seawater and salt-spray corrosion.
     
  • Flat-head Flange Screws
     
    Application: High-strength fastening for hull shell stiffeners, bulkhead frames, deck machinery foundations.
     
    Characteristics: Large flange surface distributes stress, prevents plate crushing, and adapts to irregular mounting surfaces.
     
 

1.2 Marine Power & Propulsion System

 
  • Flat-head Positioning Screws for Main Engine & Gearbox
     
    Application: Positioning and fastening of engine cylinder heads, crankcases, gearboxes, thrust bearing seats.
     
    Characteristics: Side flat structure ensures precise positioning, withstands explosion pressure and torsional impact.
     
  • Flat-head Locking Screws for Propeller Shafting
     
    Application: Locking and anti-loosening for propellers, intermediate shafts, stern shaft sealing devices.
     
    Characteristics: Cooperate with shaft keyways/flats to transmit high torque and prevent rotation loosening.
     
 

1.3 Marine Piping & Valve System

 
  • Flat-head Screws for Pipe Clamps & Supports
     
    Application: Fixing of seawater pipes, fuel pipes, hydraulic pipes, fire-fighting pipes.
     
    Characteristics: Flat head fits the clamp surface, suitable for narrow engine room spaces.
     
  • Flat-head Screws for Valve Bonnet
     
    Application: Fastening for marine globe valves, check valves, safety valves, pressure reducing valves.
     
    Characteristics: Anti-rotation flat ensures even loading of sealing surfaces, resistant to medium corrosion.
     
 

1.4 Marine Electrical & Outfitting Equipment

 
  • Flat-head Screws for Electrical Boxes & Equipment Foundations
     
    Application: Mounting of bridge consoles, radar & navigation equipment, emergency generators, lighting.
     
    Characteristics: Anti-loosening, suitable for frequent vibration, ensuring reliable electrical connection.
     
  • Flat-head Screws for Marine Furniture & Interior
     
    Application: Fixing of cabin furniture, galley equipment, sanitary units.
     
    Characteristics: Low-profile flat head, polished/passivated surface, suitable for humid indoor environment.
