Titanium Dome Head Bolt - Low Profile Design from China Suppliers & Factory for Aesthetic Fastening
Key Features
The titanium dome head bolt sports a shallow dome head that reduces protrusion, helping prevent accidental contact and protecting panels or trims. Its discreet profile keeps surfaces tidy while ensuring safe operation.
The dome-shaped head offers a clean, mechanical look while maintaining minimal bolt height. This combination of subtle styling and practical protection suits visible or exposed mounting points without compromising design harmony.
Built from Grade 5 titanium, this bolt retains strength and shape under repeated stress. It performs reliably in lightweight, high-vibration assemblies, providing secure fastening where ordinary bolts may loosen or deform.
The titanium dome head bolt combines lightweight construction with corrosion resistance for long-term use. Standard hex drive ensures reliable torque, while Torx (star) drive is also available for frequent assembly or precise fastening.

Frequently Asked Questions
Grade 5 Titanium (Ti-6Al-4V) provides an exceptional strength-to-weight ratio, high tensile strength (≥ 900 MPa), and excellent corrosion resistance. This makes it ideal for lightweight, high-vibration applications like motorcycles and bicycles.
The shallow dome head reduces external protrusion. This design prevents accidental contact or snagging, protects surrounding panels or trims, and offers a clean, streamlined mechanical appearance.
Standard configurations feature an internal Hex Socket drive for reliable torque transmission. Torx (star) drives are also available for applications requiring frequent assembly or precise fastening control.
Standard sizes range from M5 to M8 in diameter and 12mm to 25mm in length. Through our OEM customization services, we support custom thread types, head styles, lengths, and surface finishes (Natural, Polished, Anodized, PVD).
Always use the correct size hex driver to prevent head stripping. Additionally, avoid using thick washers or spacers to ensure the low-profile head sits flush against the mounting surface as intended.
