Titanium oil plug bolt

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

Titanium oil plug bolt are high-performance fasteners designed for demanding automotive, aerospace, and motorsport applications where lightweight strength, corrosion resistance, and thermal stability are critical. They serve as premium replacements for standard steel or aluminum drain plugs in oil pans, transmissions, and differentials.

1. Core Characteristics

• Material Science:

  • Constructed from Grade 5 (Ti-6Al-4V) or Grade 2 commercially pure titanium

  • Strength-to-weight ratio surpasses steel (40% lighter with comparable tensile strength)

  • Natural oxidation layer provides self-healing corrosion resistance

• Performance Attributes:

  • Temperature stable up to 600°F (315°C)

  • Immune to saltwater, acids, and automotive fluids

  • Non-magnetic (unless modified with embedded magnets)

2. Technical Advantages

• Weight Reduction:
  Saves 50-60g per plug vs. steel – critical for motorsport unsprung mass calculations.

• Corrosion Performance:
  Outlasts stainless steel in marine and road salt environments.

• Thread Integrity:
  Titanium’s self-lubricating properties resist galling, even with repeated removal.

3. Industry Applications

• Motorsports:
  Mandatory in F1, WEC, and MotoGP for weight savings and reliability under vibration.

• Aerospace:
  Used in helicopter gearboxes and auxiliary power units.

• Marine:
  Ideal for jet skis, speedboats, and offshore rig components.

• Premium Automotive:
  OEM option in Porsche GT3, McLaren, and Tesla Plaid track packages.

4. Economic Considerations

• Cost Premium:
  5-8x more expensive than steel plugs, but justified by:

  • Titanium oil plug bolt

  • Prevention of seized/stripped threads

  • Weight savings in competitive racing

5. Limitations

• Not for Impact Tools: Brittle under hammer force

• Thermal Expansion: Requires retorquing after extreme heat cycles

• Conductive Risk: Can create galvanic corrosion when paired with aluminum pans
