Product Description

Description

 

DIN939 Titanium Stub Bolts are used in applications that require high strength, durability, and corrosion resistance. These bolts are widely used in the aerospace, automotive, industrial, and marine industries.

The DIN939 Titanium Stub Screw is designed to provide a strong and secure connection between two components. Featuring an external flange, it increases surface contact area for greater strength and improved sealing.

Titanium stub bolts are available in a variety of sizes, pitches, and surface finishes to meet diverse engineering requirements.

Advantages

  1. High Specific Strength
    Titanium has a density of 4.51 g/cm³—higher than aluminium but lower than steel, copper, and nickel. Titanium alloys have a much higher strength-to-weight ratio, providing both lightweight and high-strength properties.

  2. Excellent Corrosion Resistance
    Titanium and its alloys are extremely stable in many chemical media, making them suitable for harsh and corrosive environments.

  3. Wide Temperature Resistance
    Titanium can operate normally at high temperatures up to 600 °C and low temperatures down to −250 °C, maintaining shape and mechanical performance.

  4. Non-Magnetic and Non-Toxic
    Titanium is a non-magnetic, biocompatible metal — safe for use in medical and sensitive magnetic applications.

  5. Superior Damping Capacity
    Titanium exhibits strong damping resistance under mechanical and electrical vibration.
    This property makes titanium components useful in ultrasonic, medical, and acoustic equipment, such as tuning forks, ultrasonic pulverisers, and speaker diaphragms.
