Product Overview
DIN912 titanium socket head cap screws M6 M8 (also known as cup-head screws or hex socket cylindrical-head screws) are among the most widely used types of titanium alloy screws in the industrial fastener sector. Their distinctive cylindrical head and hex socket design combine high-strength torque transmission with precise installation capabilities. Manufactured from aerospace-grade titanium alloy, this product achieves significant weight reduction while ensuring exceptional mechanical performance, making it an ideal fastening solution for high-end equipment manufacturing, precision instrument assembly, and weight-reduction modifications.
The product complies with the German DIN 912 standard (equivalent to ISO 4762) and features a 6g precision metric thread, ensuring perfect compatibility with all standard hex wrenches.

Surface Treatment
1. Natural Pickled Finish: Natural silver-gray metallic color-the most classic industrial style
2. Colored Anodized Finish: Gold, blue, purple, green, rainbow, etc.
-colors are produced by forming a TiO₂ interference film on the surface through electrolytic oxidation, which does not alter the thread dimensions and provides both fingerprint resistance and enhanced wear resistance
3. PVD Coating: Gold-like (TiN), black (DLC), etc.-offers a more decorative finish
4. Polished: Mirror finish or brushed effect
Key Advantages
- Lightweight: With a density of only 4.51 g/cm³, it is approximately 42% lighter than steel (7.8) and has the highest specific strength (strength/density) among metals
- Ultra-high strength: GR5 has a tensile strength of ≥895 MPa, approaching that of 45# quenched and tempered steel
- Excellent Corrosion Resistance: Virtually no corrosion in seawater, chloride ion, or acidic/alkaline environments; never rusts; no protective coating required
- Non-magnetic and Biocompatible: Does not interfere with electronic devices; suitable for equipment used in medical implant applications
- High and Low Temperature Resistance: Operating temperature range of -253°C to 400°C; does not become brittle at low temperatures
- Wide Range of Anodized Colors: Meets the personalized needs of the aftermarket
Application Scenarios and Uses
Titanium alloy cylindrical-head hex socket screws are widely used in the following fields due to their combined advantages of light weight, high strength, corrosion resistance, and non-magnetic properties:
🚴 Sports & Outdoor / Bicycle Modifications
Full-bike weight reduction for road bikes, mountain bikes, and folding bikes-including handlebar stems, seatpost clamps, disc brake adapters, water bottle cages, brake levers, and shifting components. They reduce weight, resist rust, withstand rain and sweat, and offer a premium feel.
✈️ Drones / Model Aircraft / Robots
Frame mounts, arms, gimbals, motor mounts, and precision structural components-lightweight, high-strength, and vibration-resistant; non-magnetic to prevent interference with flight controllers and electronic sensors.
🚀 Aerospace / Military Equipment
Airborne equipment, instrument mounts, cabin interiors, and precision structural assemblies-resistant to high and low temperatures, corrosion-resistant, highly reliable, and requiring no long-term maintenance.
🏥 Medical Devices / Wearables
Medical instrument mounts, surgical instruments, rehabilitation equipment, high-end eyeglass frames, watches, and smart wearable accessories-biocompatible and hypoallergenic, free of heavy metals, and non-magnetic.
⚓ Chemical / Marine / Shipbuilding
Seawater equipment, shipboard components, chemical piping, and corrosion-resistant equipment-permanently rust-free in acidic and alkaline environments and in salt-fog coastal areas.
🔬 Precision Instruments / Electronic Equipment
Testing instruments, laboratory equipment, communication base stations, radar components-non-magnetic to prevent circuit interference, high precision, and resistant to deformation.
🏎️ New Energy / Automotive and Motorcycle Modifications
New energy battery enclosures, electronic control components, race cars, motorcycle modifications, lightweight chassis, and exterior decorative fasteners.
