Titanium Nut M6 M8 M10 M12 Flange Nylon Insert Hex Lock Nuts, Pitch 1/1.25/1.5mm, by Tianswer

Self-locking Grade 5 Ti-6Al-4V titanium flange hex lock nuts engineered with an internal nylon collar for extreme vibration resistance and permanent locking reliability across motorcycle, bicycle, and automotive builds.

Engineering & Locking Mechanism

Precision CNC-machined from aerospace-grade Ti-6Al-4V (TC4 Grade 5) titanium alloy, these flanged lock nuts combine the high strength-to-weight ratio of titanium with a self-contained prevailing-torque nylon insert. As mating bolt threads engage the elastic nylon collar, the polymer deforms elastically around the threads, generating continuous frictional clamping that prevents loosening under severe mechanical shock and high-frequency engine vibration. The integrated flange distributes clamp loads over a wider surface area, eliminating the need for independent washers.

Key Applications

• Motorcycles & Scooters: Sprocket bolts, exhaust hanger brackets, shock linkage pivots, and engine mounts subjected to constant harmonic vibration.
• Mountain Bikes & E-Bikes: Suspension linkages, swingarm pivots, and disc brake adapter hardware where zero-play security is critical.
• Motorsport & Track Builds: Steering linkages, sway bar end links, and chassis subframes requiring lightweight, fail-safe fastening.

Installation & Usage Recommendations

For optimal locking performance, thread the nut by hand until the bolt reaches the nylon collar, then torque to specification using a calibrated hand wrench. Avoid high-speed pneumatic impact guns, as excessive friction heat can compromise the nylon insert. Apply a light coat of anti-seize paste to the leading metal threads to prevent titanium galling.
