China Grade 5 Titanium Hex Socket Set Screws Suppliers - Lightweight & Corrosion-Resistant Fasteners from Factory
Key Features
Excellent Corrosion Resistance
Titanium grub screws resist rust, moisture, and road salt far better than standard steel set screws. The threads remain easier to remove or adjust after long-term outdoor use.
Stable Locking Under Vibration
Titanium responds well to repeated engine vibration and road impact. In small locking or adjustment points, these titanium set screws help maintain steady holding force during regular riding.
Lightweight Performance Upgrade
These titanium grub screws are about 45% lighter than same size steel screws while keeping the strength needed for motorcycle and bicycle assemblies. Less weight, without changing the fastening layout.
Durable Anodized Finish
Rainbow, blue, gold, black, and polished finishes give visible hardware a lasting metallic look. The anodized surface resists early fading and keeps custom details looking sharper over time.
Precision Hex Socket Fitment
The hex socket is precision formed for close wrench contact. This reduces tool slip during installation and helps protect both the socket edges and the hex key.
Installation & Maintenance Guidance
Use Anti-Seize on Aluminum Threads. Apply anti-seize when Titanium Grub Screws are installed in aluminum components. This reduces thread galling and makes later adjustment or removal easier.
Use the Correct Hex Key Size. Always match the hex key to the socket size. Worn or incorrect tools can damage small hex sockets during installation.
Match the Screw Point to the Contact Surface. Flat point screws suit smooth contact surfaces and repeated adjustment. Oval or cup point styles may be considered for uneven surfaces or stronger locking needs.

Application Scenarios
Motorcycle Applications
● Clutch & Brake Lever Adjustment
Titanium grub screws are used for clutch and brake lever reach adjustment. M4 and selected M7 sizes suit compact motorcycle control assemblies.
● Exhaust Baffle / DB Killer Retention
Titanium set screws can secure exhaust baffles and DB killers. They are useful where heat, moisture, and corrosion make steel screws difficult to remove.
● Rearset, Shift Linkage & Bar-End Mirror Locking
Used for rearset positioning, shift linkage adjustment, and bar-end mirror locking. These small fastening points need compact screws with steady hold.
Bicycle & Other Applications
● Derailleur & Handlebar Accessory Adjustment
Titanium grub screws suit derailleur H/L limit adjustment and handlebar accessory locking. They work well on lightweight bicycle assemblies.
● EDC, Optical & Precision Equipment Positioning
Hex socket set screws are used in EDC tools, optical devices, and compact precision assemblies. They fit internal positioning and hidden locking points.
Frequently Asked Questions (FAQ)
Why are titanium grub screws preferred over steel options?
Titanium grub screws are approximately 45% lighter than steel screws while matching their strength. They also offer superior resistance to corrosion, rust, and road salt, ensuring long-term adjustability and durability.
Why is it recommended to use anti-seize during installation?
Applying anti-seize compound is highly recommended when installing titanium grub screws into aluminum components. This prevents thread galling (cold welding) and ensures easy adjustment or removal in the future.
What sizing standards do these titanium set screws conform to?
These screws follow the Metric Thread standard, specifically complying with DIN 913 and ISO 4026 styles. They are available in thread sizes from M3 to M8 and lengths ranging from 3mm to 25mm.
What surface finishes and colors are available?
We offer polished, anodized, and PVD surface processes. Available colors include rainbow, blue, gold, black, and natural polished finishes that resist early fading.
Do you support custom sizes or OEM requests?
Yes, OEM customization is fully supported. We can customize the size, length, finish, color, and packaging details according to your specific project requirements.
How do I prevent damaging the hex socket during installation?
Always use the correct, unworn hex key size that perfectly matches the screw socket. The precision-formed drive ensures close contact, but using incorrect or worn tools can strip the socket edges.
