M6x20mm Titanium Bolts for MTB Caliper
This pack uses durable TC4 Titanium Alloy designed for anti-corrosion performance. It’s suitable for caliper fixing and may also fit crank arms or some stems. Please verify the bolt size, especially OD and length, against your brake components to avoid incompatibility. The color finish is oil slick, offering a distinct look while maintaining strength and low weight.
M5x18mm Titanium Bolts for Stem
These TC4 titanium bolts are crafted for stem fixation and may also accommodate fixings for front and rear derailleur grip rings, seat post clamps, and related components. Finely polished with a nitride coating for color and wear resistance. Check the displayed dimensions to ensure compatibility with your specific stem and frame hardware.
Wanyifa Titanium M5x20mm with Washer
Details specify size, thread pitch, and head dimensions. Material is 6AL/4V TC4 Grade 5 titanium alloy with anti-corrosion and high-strength properties. The package notes emphasize correct sizing prior to purchase; verify that M5x20mm matches your stem and related fittings. Weight per bolt is light, and the set includes washers for secure mounting.
VBESTLIFE M5x18mm Stem Bolts with Washers
These multicolor round-head bolts are designed for stem applications with washers included. Made from alloy for high strength and durability, they are lightweight and portable. The product emphasizes easy handling and reliable performance for securing the stem and related components. Ensure compatibility with your stem system by confirming the M5 thread and length.
uxcell M6x35 Titanium Stem Bolts
The uxcell kit offers a durable titanium tone with M6x35mm thread size. The total size is provided to help determine fit for most mountain bikes, BMX, and road bikes. The bolts are described as corrosion-resistant with good wear resistance and strength. Before purchase, verify thread size and stem compatibility with your bike’s headset and front end.
NELboNs Titanium Bolts for Disc Brakes
Colored by PVD vacuum nitride coating, these titanium inserts and pins are designed for disc brake pad pins and related threaded components. The kit emphasizes precise threads and lightweight construction, with a focus on durability under braking loads. Check compatibility with your brake model and pad pin interface before purchasing.
Buying Guide: Key Considerations For Titanium Mountain Bike Bolts
- Material and finish: Titanium alloys (6AL/4V, TC4) offer high strength-to-weight, corrosion resistance, and durability. Finishes like oil slick or nitride coatings add color and wear resistance while helping identify different bolt types on the bike.
- Size and thread compatibility: Common sizes include M5 and M6 with pitches around 0.8 mm. Measure thread diameter, length, and head type (flat, button, or hex) to ensure a proper fit for stems, calipers, rotors, and derailleurs components.
- Head style and washers: Pan/round heads or hex heads can affect the interface with components. Washers are often included to distribute clamping force and protect soft aluminum surfaces.
- Weight savings vs. strength: Titanium is lighter than steel while maintaining sufficient torque tolerance. Ensure you’re selecting bolts with appropriate shear and clamping strength for high-stress areas like caliper mounting or stem clamping.
- Application scope: Some bolts are multi-use (calipers, stems, derailleurs, seat posts). Double-check the intended application and any notes about compatibility with other components in your setup.
- Installation and torque: Follow manufacturer torque guidance. Over-tightening titanium can strip threads or damage carbon/aluminum interfaces; use thread locker only if recommended by the component manufacturer.
- Color and identification: If you’re color-coding hardware for maintenance or trail aesthetics, verify that the color coating will endure UV exposure and braking heat without flaking or fading.
