DIN 933 Titanium Bolts

Overview

DIN 933 titanium bolts are high-strength fasteners made from titanium or titanium alloys, designed

according to the DIN 933 standard. This standard specifies the technical requirements for fully

threaded hexagon head bolts with metric coarse threads. Titanium bolts are widely used in

industries that demand lightweight, corrosion-resistant, and high-strength fasteners,

such as aerospace, marine, chemical processing, and medical applications.

Key Features

1. Material Properties
   • Titanium (Grade 2, Grade 5 – Ti-6Al-4V) offers excellent strength-to-weight ratio,
   • corrosion resistance, and biocompatibility.
   • High tensile strength, comparable to steel but with about 45% less weight.
   • Exceptional corrosion resistance, especially in saltwater, chlorine, and acidic environments.
2. DIN 933 Specifications
   • Fully threaded shank for maximum grip and load distribution.
   • Hexagon head for easy installation using standard wrenches.
   • Metric coarse threads (M1.6 to M100) as per ISO standards.
   • Property classes: Typically available in strength grades equivalent to 8.8, 10.9, or 12.9 in steel bolts.
3. Advantages Over Steel Bolts
   • Lightweight: Ideal for applications where weight reduction is critical (e.g., aircraft, racing cars).
   • Non-magnetic & Non-conductive: Suitable for electronic and MRI equipment.
   • Biocompatible: Used in medical implants and surgical instruments.
   • Oxidation-resistant: Forms a protective oxide layer, preventing rust.

Common Applications

• Aerospace: Engine components, airframe structures.
• Marine: Shipbuilding, offshore platforms.
• Chemical Industry: Reactors, pipelines in corrosive environments.
• Medical: Bone screws, dental implants.
• Automotive & Motorsports: High-performance vehicles.

Conclusion

DIN 933 titanium bolts provide an optimal combination of lightweight design, durability, and

corrosion resistance, making them indispensable in demanding industries. Their compliance

with the DIN 933 standard ensures reliability and interchangeability in mechanical assemblies

worldwide.

For specialized applications, custom coatings (e.g., anodizing) or alloy variations

(e.g., Grade 5 titanium) can further enhance performance.
