China Titanium Chamfered Hex Socket Cap Bolt with Washer - Motorcycle Supplies from Trusted Factory Suppliers
Key Features
Chamfered Top for Safe & Compact Fit
The titanium chamfered hex socket cap bolt with washer features a smooth chamfer around the top edge, reducing the risk of scratching nearby painted or aluminum parts and allowing secure installation in tight spaces. Its compact head design fits well in areas where standard cylindrical heads may feel crowded.
High Strength, Low Weight
Made from Grade 5 titanium, this bolt provides excellent tensile and yield strength while weighing much less than steel counterparts. The Titanium chamfered hex socket cap bolt with washer ensures strong, reliable fastening for motorcycles, bicycles, and other lightweight assemblies.
Semi-fixed Washer for Stable Preload
The integrated semi-fixed washer maintains even clamp load under vibration, reduces micro-movement between assembled parts, and supports long-term joint stability in dynamic applications.
Hex Socket Drive
The internal hex socket ensures precise tool engagement, allowing controlled torque application and reducing the risk of rounding. This provides reliable fastening even in compact or high-vibration assemblies.
Installation & Maintenance Guidance
Check Washer Seating: After tightening, ensure the semi-fixed washer is properly seated. This keeps clamp load even and protects painted surfaces.

Frame Nodes & Subframe Interfaces
Ideal for frame joints (M6–M8 × 20–35 mm). Its chamfered head reduces edge interference and ensures precise alignment, providing durable titanium fasteners for structural motorcycle assemblies.
Suspension Linkages & Pivot Blocks
Designed for lightweight linkage points (M5–M6 × 12–25 mm). The chamfered head allows easier wrench access in compact areas and supports even preload for consistent assembly performance.
Engine Side Covers & Thin-wall Casings
Suitable for slim covers (M5–M6 × 10–20 mm). The chamfered top reduces interference with surrounding parts, ensuring secure fastening in visible or thin-wall motorcycle components.
Bicycle / E-bike
Accessory Mounts
Perfect for bottle cages, fenders, and light mounts (M5 × 10–18 mm). The titanium chamfered hex socket cap bolt with washer combines lightweight design with aesthetic appeal, providing secure attachment while minimizing edge impact risk.
Frequently Asked Questions (FAQ)
What are the main advantages of using Grade 5 Titanium for these bolts?
Grade 5 Titanium (Ti-6Al-4V) offers an outstanding strength-to-weight ratio. It provides a high tensile strength of ≥ 900 MPa and yield strength of ≥ 830 MPa while weighing significantly less than steel. Additionally, it offers excellent resistance to corrosion from moisture, salt, and mild chemicals.
How does the chamfered top head design benefit installation?
The chamfered top features a smooth, rounded edge that prevents the tool or bolt head from scratching nearby painted or aluminum components. It also allows for a compact fit, making it ideal for tight, narrow, or crowded installation spaces.
What is the purpose of the integrated semi-fixed washer?
The semi-fixed washer helps to distribute the clamping force evenly across the contact surface. This maintains a stable preload, reduces micro-movement or loosening under high vibration, and protects critical surfaces from damage.
What sizes and thread standards do these bolts conform to?
These bolts are available in diameters ranging from M5 to M8 and lengths from 10mm to 40mm, with metric coarse or fine thread pitches (0.8–1.25 mm). They conform to DIN 912 and ISO 4762 standards with an ISO 6g thread tolerance.
Can I customize the surface finish or request OEM options?
Yes, OEM customization is fully supported. You can select from various surface finishes, including Natural Titanium, Polished, Anodized, and PVD Coating. Custom lengths, thread types, head styles, and logo engraving are also available.
