Customisation M3 M16 Titanium Alloy TA1 TA2 TC4 Hex Metal Bolts for Aerospace and Medical Machines

Hexagon head bolts, also known as hexagon head screws, are metal fasteners primarily used for connecting components in construction, machinery, photovoltaic mounting systems, bridges, and chemical equipment. Classified by performance, they comprise standard bolts (e.g., Grade 4.8, Q235 material) and high-strength bolts (e.g., Grade 8.8, Grade 10.9, utilising 45# steel or 20MnTiB material). High-strength bolts are further categorised by load transfer characteristics into friction-type (where plate sliding defines the ultimate limit state) and bearing-type (where connection failure defines the ultimate limit state).
Materials encompass carbon steel, stainless steel (SUS304/316L), and silicon bronze, with surface treatments including hot-dip galvanising and blue-white zinc electroplating to enhance corrosion resistance. Thread specifications range from M4 to M100, with lengths up to 500mm, conforming to international standards such as GB/T, DIN, and ISO. Anti-loosening measures incorporate methods such as spring washers and split pins. Ordinary bolts are suitable for temporary connections and are reusable, whilst high-strength bolts are predominantly used for permanent connections.

Hex bolts are widely used across various industries due to their simple design, high strength, and ease of installation. Below are key applications and advantages:

• High Strength-to-Weight Ratio: Ideal for aerospace and automotive applications where weight reduction is critical.
• Superior Corrosion Resistance: Resistant to rust, seawater, and harsh chemicals for long-term durability.
• Biocompatibility: Safe for medical implants and prosthetics with no allergic reactions.
• Thermal Stability: Maintains mechanical properties at high temperatures.
• Non-Magnetic Properties: Suitable for MRI machines and sensitive electronic environments.
• Fatigue Resistance: Withstands repeated stress cycles for extended service life.
• Aesthetic Appeal: Distinct silver-gray finish for applications where appearance matters.
• Recyclability: Environmentally friendly with high recyclability.
• Design Flexibility: Allows creation of complex shapes for optimized performance.

• High Strength-to-Weight Ratio: Tensile strength exceeding 930 MPa with density half that of steel.
• Corrosion Resistance: Forms passive oxide film to withstand harsh environments without protective coatings.
• Biocompatibility: Excellent for medical implants including hip/knee replacements and dental applications.
