China Suppliers Factory Titanium Chamfered Hex Socket Cap Bolt with Washer for Motorcycles and Bicycles
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
Q
What material is used for these chamfered hex socket cap bolts?
These bolts are manufactured from Grade 5 Titanium (Ti-6Al-4V), offering high tensile strength (≥ 900 MPa) and yield strength (≥ 830 MPa) while remaining lightweight compared to steel.
Q
What are the benefits of the chamfered top design?
The chamfered top edge creates a smooth contour that minimizes the risk of scratching adjacent painted or aluminum parts. It also allows for safe and compact installation in tight, restricted spaces.
Q
How does the semi-fixed washer function?
The integrated semi-fixed washer helps maintain a stable and even clamp load under vibration, reduces micro-movement between joint components, and protects mounting surfaces from wear.
Q
What thread sizes and length ranges are standard?
The standard diameter range is M5 to M8, with lengths spanning from 10 mm to 40 mm. Thread options include both metric coarse and fine pitches.
Q
Are custom finishes and OEM options available?
