Specifications

12-point head titanium screw typically refers to a screw with a 12-pointed, star-shaped head design, which offers a higher level of torque and grip compared to traditional screws. 
12-point head titanium screw is a specialized fastener designed for high-strength, lightweight, and corrosion-resistant applications, featuring a unique drive system that requires a matching 12-point socket wrench.

 

 

 

 

Head Design

 

The screw features a 12-pointed head, meaning there are twelve contact surfaces for the driver. This design allows for better torque transfer and a more secure fit compared to hex or square heads.

  • Also Known As: Double Hex or Triple Square (though true triple square has a different profile, the terms are often used interchangeably in some industries).
  • Design: The head has 12 equally spaced recessed points (forming 24 contact points) that engage with a matching 12-point socket.
  • Purpose and Advantages:
  • High-Torque Capability: Allows for higher torque application with less risk of rounding compared to standard 6-point hex (Allen) drives.
  • Multiple Engagement Angles: The socket can be engaged at 30-degree increments (12 positions), making it ideal for tight spaces where swing arc is limited.
  • Reduced Fretting and Wear: The design distributes driving force more evenly.
  • Secure Fit: The geometry provides excellent grip, minimizing cam-out.

 

Material

 

The screw is made from titanium material which is a lightweight, corrosion-resistant, and high-strength metal, making it ideal for applications where strength-to-weight ratio, durability, and resistance to harsh environments (like seawater or chemicals) are critical.

  • Grade 5: This is the most commonly used titanium alloy for bolts, offering exceptional strength, lightness, and resistance to corrosion. It has a high tensile strength, excellent fatigue resistance
  • Grade 2: This is a commercially pure titanium, often used in applications that require excellent corrosion resistance and strength without the need for the higher strength of alloyed titanium grades.

 

Size/Threading

 

The size (diameter) and length of the screw can vary depending on the application. Commonly, screws of this type come in standard sizes such as M4, M5, M6, etc., with appropriate threading (metric or imperial) for the intended use.

 

Load Capacity

 

The screw's titanium material offers excellent strength while keeping the overall weight low. The 12-point head also ensures that the screw can withstand high amounts of torque without stripping or slipping.

 

Application

 

These screws are typically used in precision industries like :

  • Aerospace: Structural components in airframes and jet engines where weight savings and reliability are paramount.
  • Automotive (High-Performance/Racing): Engine components, drivetrain, and suspension systems.
  • Medical Devices: Orthopedic and spinal implants.
  • Precision Machinery: Where high clamp loads and repeated disassembly are required.
  • Marine and Chemical Processing: Due to titanium's corrosion resistance.
