China Suppliers Titanium Chamfered Hex Socket Cap Bolt with Washer - Factory Direct 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.

Application Scenarios
Well-suited for caliper bridges (M6–M8 × 15–30 mm). The titanium chamfered hex socket cap bolt with washer eases tool entry and keeps preload consistent in vibration-prone areas, making it reliable motorcycle hardware.
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.
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.
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.
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) provides an exceptional strength-to-weight ratio, delivering the high tensile and yield strength of steel at a fraction of the weight. It also offers outstanding natural corrosion resistance against moisture, salt, and mild chemicals.
What is the purpose of the chamfered top design?
The chamfered top features a smooth, sloped edge that minimizes the risk of scratching adjacent painted or aluminum surfaces. It also allows for easier installation and tool access in tight, compact spaces where standard cylindrical bolt heads might cause interference.
How does the semi-fixed washer improve joint stability?
The integrated semi-fixed washer helps distribute the clamp load evenly across the mating surface. This reduces micro-movement between assembled parts and maintains a stable preload, which prevents the bolt from loosening under dynamic vibration.
What sizing and customization options do you offer?
We supply standard diameters from M5 to M8 and lengths ranging from 10mm to 40mm. For customization, we support OEM requests for specific thread types, head styles, custom finishes (like anodizing or PVD coatings), and logo engraving.
What standards do these hex socket cap bolts comply with?
Our titanium chamfered hex socket cap bolts with washers are manufactured in compliance with DIN 912 and ISO 4762 dimensional and mechanical standards, ensuring reliable compatibility and performance.
