Core Technical Characteristics

2.1 Structural Design Advantages

• Anti-loosening: Flat head matches mounting surface/slot to prevent self-loosening.
• Stable torque transmission: Even force distribution, less prone to thread slipping.
• Space-saving: Low-profile head, suitable for confined installation spaces.
• Precise positioning: Flat structure used as positioning reference.

2.2 Material & Corrosion Resistance

• Main materials: 316L/317L stainless steel, duplex 2205/2507, titanium alloy, Monel alloy.
• Surface treatments: Hot-dip galvanizing, zinc infiltration, Teflon coating, passivation.
• Compliance: Meets high corrosion protection requirements of ISO 12944.

2.3 Mechanical Performance

• High strength: Tensile strength 800–1200MPa, yield strength 600–900MPa.
• Vibration & fatigue resistance: Stress distribution design improves fatigue life.
• Impact resistance: Withstands wave impact, engine vibration, equipment startup/shock.

2.4 Processing & Standardization

• Customized: Designed and manufactured in accordance with classification societies (CCS, LR, DNV, ABS).
• Processing: Cold heading, hot forging, CNC precision machining.
• Testing: Tensile, hardness, salt spray, NDT (UT/MT).

3. Selection & Installation Guidelines

1. Material selection: 316L/duplex/titanium for seawater/salt-spread areas; galvanized carbon steel for engine rooms.
2. Flat dimension: Thickness ≥3mm to ensure strength.
3. Anti-loosening methods: Split pins, wire locking, nylon lock nuts, anaerobic adhesives.
4. Torque: Install according to classification society torque standards.
