Features and Applications of DIN 912 Titanium Alloy Cylindrical-Head Hex Socket Screws

For a complete overview of the DIN 912 Titanium Alloy Cylindrical-Head Hex Socket Screws, including materials, key features, and manufacturing processes, please refer to the detailed breakdown below.

Features of DIN 912 Titanium Alloy Cylinder Head Hex Socket Screws:

I. Basic Standards

Standard Model: DIN 912 (German Standard)

Equivalent Standards: ISO 4762, GB/T 70.1

Type: Cylindrical-head (countersunk) hex socket screw

Thread Tolerance: 6g Precision Metric Thread

Common Sizes: M3, M4, M5, M6, M8, M10, M12

II. Common Materials

TC4 / Gr5 (Ti-6Al-4V): High strength, fatigue resistance, and properties comparable to 10.9-grade steel; the primary material used in the machinery, defense, bicycle, and equipment industries.

TA2 / Gr2: Pure titanium with exceptional corrosion resistance and good toughness; suitable for applications in the chemical industry, seawater environments, and medical devices requiring corrosion resistance.

III. Key Features

Lightweight with a density of just 4.43 g/cm³, 40% lighter than steel screws, making it the top choice for lightweight modifications.

High strength and fatigue resistance: TC4 offers high strength; the roll-forming process ensures intact metal fibers, providing shock resistance and breakage resistance, making it suitable for equipment subject to long-term vibration.

Rust-proof: Resistant to salt spray, seawater, acids, alkalis, and humid environments; offers superior corrosion resistance compared to 304/316 stainless steel.

Non-magnetic: Does not interfere with precision instruments, sensors, medical equipment, or electronic devices.

High-temperature and low-temperature resistance: Does not soften at high temperatures or become brittle at low temperatures; suitable for harsh operating conditions.

Attractive finish: Available in natural finish, pickled and passivated, sandblasted, or anodized (gold, blue, purple, black) for a high-end, refined appearance.

IV. Manufacturing Process

Blanking → Cold heading to form cup heads → Fine trimming and chamfering → Precision thread rolling → Degreasing and cleaning → Surface treatment → 100% inspection with go/no-go gauges → 3.1 Material Certificate. Key points: Threads must be rolled, not machined; no tool marks, no folds, and no micro-cracks.

V. Available Options

Stock standard sizes, custom non-standard designs, custom lengths, anodized color options, EN 10204 3.1 Material Certificate.
