Check thread coverage and fit
The existing listing notes that lengths up to 25 mm are fully threaded, while longer sizes differ. Confirm the selected length's shank and thread configuration, head seat, clearance and engagement against the original bolt. Use the component manufacturer's fastener specification and tightening instructions where loads or safety are involved. To learn more about fastener selection, shank geometry, and thread integrity, read our Ultimate Guide to Choosing Titanium Fasteners.
