Description
SUS304 Positioning Screws - Semi Threaded High Load Ship Component
M5 positioning screws, semi-threaded screws, and special-head adjusting screws - high-precision marine hardware
Typical Applications in Shipbuilding Industry
Hull Structure & Deck System
  • Marine Flat-head Eye Bolts with Hole: Connection of deck railings, hatch covers, ladders, bollards, ventilators and other movable/detachable structures. 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: High-strength fastening for hull shell stiffeners, bulkhead frames, deck machinery foundations. Large flange surface distributes stress, prevents plate crushing, and adapts to irregular mounting surfaces.
Marine Power & Propulsion System
  • Flat-head Positioning Screws for Main Engine & Gearbox: Positioning and fastening of engine cylinder heads, crankcases, gearboxes, thrust bearing seats. Side flat structure ensures precise positioning, withstands explosion pressure and torsional impact.
  • Flat-head Locking Screws for Propeller Shafting: Locking and anti-loosening for propellers, intermediate shafts, stern shaft sealing devices. Cooperate with shaft keyways/flats to transmit high torque and prevent rotation loosening.
Marine Piping & Valve System
  • Flat-head Screws for Pipe Clamps & Supports: Fixing of seawater pipes, fuel pipes, hydraulic pipes, fire-fighting pipes. Flat head fits the clamp surface, suitable for narrow engine room spaces.
  • Flat-head Screws for Valve Bonnet: Fastening for marine globe valves, check valves, safety valves, pressure reducing valves. Anti-rotation flat ensures even loading of sealing surfaces, resistant to medium corrosion.
Marine Electrical & Outfitting Equipment
  • Flat-head Screws for Electrical Boxes & Equipment Foundations: Mounting of bridge consoles, radar & navigation equipment, emergency generators, lighting. Anti-loosening, suitable for frequent vibration, ensuring reliable electrical connection.
  • Flat-head Screws for Marine Furniture & Interior: Fixing of cabin furniture, galley equipment, sanitary units. Low-profile flat head, polished/passivated surface, suitable for humid indoor environment.
Offshore Engineering & Special Vessels
  • Flat-head Lifting Eye Screws: Lifting and fixing of offshore modules, crane booms, life-saving equipment. Integrated flat and lifting eye, high load-bearing capacity.
  • Flat-head Sealing Screws for Underwater Equipment: Pressure-resistant sealing for ROVs, diving bells, subsea valves. Face seal with O-ring, withstands high pressure; titanium alloy for anti-magnetic and corrosion resistance.
