Drilled flange-head M10 bolt for a measured lockwire installation. This Tianswer fastener is listed in Grade 5 Ti-6Al-4V (TC4) titanium alloy with M10 × 1.25 threads and small holes in the head. A drilled head provides a place for correctly installed safety wire; it does not secure the bolt on its own.

Installation checks
Verify the original thread pitch, head bearing surface, length and thread coverage. Safety wiring must follow the equipment or racing organization's procedure, with wire orientation that resists loosening. Use manufacturer-approved hardware and tightening requirements for any safety-critical assembly.

FAQ
Is a hole the same as a locking mechanism? No. Correct wire selection and installation are separate steps.
