Grade2 Titanium Hex Allen Socket Button Head Screws is a high-strength fastener made of titanium alloy material with hexagon socket on the head, widely used in aerospace, medical equipment, chemical and high-end manufacturing fields. It has excellent characteristics such as lightweight, high specific strength, corrosion resistance, and non-magnetic.
Core Features and Advantages
Ultra light and high strength: The density is about 4.51 g/cm ³, which is only 58% of steel, but the strength is comparable to medium strength steel, significantly reducing structural weight and suitable for scenarios sensitive to weight reduction (such as the C919 aircraft requiring about 200000 pieces of titanium fasteners per unit).
Excellent corrosion resistance: The surface can form a dense oxide film, which is stable in oxidizing, neutral, and weakly reducing media. Its resistance to seawater and acid-base corrosion far exceeds that of stainless steel, making it suitable for marine engineering and chemical equipment.
Good biocompatibility: non-toxic, non allergenic, in compliance with medical implant standards, commonly used in medical devices such as fracture fixation and dental implants.
Non magnetic: The magnetic permeability is close to 1, suitable for strong magnetic field environments such as MRI equipment and precision electronic instruments, to avoid signal interference.
Colorable and aesthetically pleasing: Through anodizing treatment, it can present various colors such as blue, gold, purple, etc., enhancing the appearance design of the product, commonly seen in high-end consumer goods.

What are the common grades of titanium used for screws, and how to select the right titanium material based on working conditions?
The selection of titanium material for hexagon socket button head screws should be based on operating temperature, corrosive media, and load requirements as the core matching criteria. The common titanium grades and their recommended applications are as follows:
| Grade | International Equivalent | Tensile Strength | Key Characteristics | Recommended Applications |
|---|---|---|---|---|
| GR2 | CP Titanium | 345–480 MPa | Commercially pure titanium; excellent corrosion resistance, good plasticity, but relatively low strength | Marine engineering, chemical equipment, seawater desalination devices, decorative parts, and other low‑load applications |
| GR5 | Ti‑6Al‑4V | 900–1100 MPa | α+β duplex titanium alloy; best overall performance, accounting for about 70% of the titanium screw market | Aerospace, medical devices, automotive tuning, high‑load structural connections (engines, suspension systems, etc.) |
| GR7 | Ti‑0.2Pd | ~345 MPa | Palladium addition further improved corrosion resistance, especially against crevice corrosion | Medium‑to‑high temperature corrosive environments (300–400 °C); special connections in chemical equipment |
| GR12 | Ti‑0.3Mo‑0.8Ni | ~483 MPa | Molybdenum and nickel addition; strong resistance to reducing acids | High‑temperature chloride environments, evaporation crystallisation equipment, and chemical processing units |
| TB3 | Beta titanium alloy | 800–950 MPa | β‑type titanium alloy; good elasticity and excellent fatigue resistance | Frequently disassembled parts, quick‑release devices |
Selection advice:
GR5 for high‑load structures
GR2 for corrosion‑priority but low‑load applications
TB3 for frequent disassembly/reassembly
GR7 or GR12 for high‑temperature corrosive environments
In biomedical implant applications, both GR1/GR2 commercially pure titanium and GR5 meet biocompatibility requirements – no metal ion release after 20 years of implantation.
Applications of Grade 2 titanium hex Allen socket button head screws
Grade 2 titanium hex Allen socket button head screws are a reliable and long-lasting choice for a variety of applications, including but not limited to aerospace, medical devices, marine equipment, automotive parts, and outdoor equipment.
Marine Equipment: Saltwater environments can be incredibly harsh on metal components. However, Titanium Grade 2 hex Allen socket button head screws are highly resistant to corrosion, making them suitable for marine equipment such as boats, ships, and offshore platforms.
Automotive Industry: The high strength and light weight of Titanium Grade 2 make it an attractive option for automotive manufacturers looking to reduce weight and improve fuel efficiency. Hex Allen socket button head screws made from this material are commonly used in engine components, suspension systems, and exhaust systems.
Outdoor Equipment: Titanium Grade 2 hex Allen socket button head screws are also commonly used in outdoor equipment such as camping gear, bicycles, and climbing equipment, where their corrosion resistance and strength are highly valued.
How are the strength grades of titanium screws classified, and what is the highest grade they can achieve?
The strength grades of titanium screws are generally divided into 8.8, 10.9, and 12.9 according to international standards. The specific parameters are as follows:
| Strength Grade | Tensile Strength | Yield Strength | Applicable Scenarios |
|---|---|---|---|
| Class 8.8 | ≥800 MPa | ≥640 MPa | General connection applications with moderate loads |
| Class 10.9 | ≥1000 MPa | ≥900 MPa | High‑load applications (e.g., automotive chassis, engine surroundings) |
| Class 12.9 | ≥1200 MPa | ≥1080 MPa | Ultra‑high strength special applications (e.g., aircraft engines, racing car components) |
GR5 titanium alloy screws have a tensile strength of 900–1100 MPa, which corresponds to approximately Class 10.9 to near Class 12.9. It is worth noting that the specific strength (strength‑to‑density ratio) of titanium screws is 2.2 times that of steel; therefore, under the same strength requirement, the weight of titanium screws can be significantly reduced.
Special note: Although the absolute tensile strength of titanium screws is comparable to that of high‑grade alloy steel, their elastic modulus is about half that of steel. This means that under the same load, titanium screws exhibit greater elastic deformation, and the tightening torque must be adjusted accordingly.
