Titanium Chamfered Hex Socket Cap Bolt with Washer for Motorcycles - China Suppliers and Factory - M5 to M8 Sizes
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
ℹ
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)
Q What material are these chamfered hex socket cap bolts made of?
These bolts are made of premium Grade 5 Titanium (Ti-6Al-4V), offering high tensile strength (≥ 900 MPa) and yield strength (≥ 830 MPa) with exceptional corrosion resistance and a low density of 4.43 g/cm³.
Q What is the benefit of the chamfered top design?
The chamfered top edge creates a smooth contour that prevents scratching on surrounding painted or aluminum components during installation. It also allows for a compact fit in tight, space-restricted applications.
Q What functions does the semi-fixed washer perform?
The integrated semi-fixed washer ensures an even clamp load distribution under high vibration, reduces micro-movements between the joined surfaces, and protects sensitive surfaces from scoring.
Q What sizes and thread pitches are available?
They are available in a diameter range of M5 to M8, length range of 10 to 40 mm, and thread pitches ranging from 0.8 to 1.25 mm. The threads conform to Metric Coarse/Fine standards with an ISO 6g tolerance.
Q Can these bolts be customized with different colors or logos?
Yes, we support full OEM customization, including surface finishes (Natural, Polished, Anodized, or PVD Coating), custom lengths, thread profiles, and custom logo engraving.
