Why these bolts stand out
- 8740 chrome moly delivers superior strength and fatigue resistance, helping maintain secure flexplate clamping under high engine loads
- Black oxide finish provides robust corrosion protection in the engine bay while maintaining a low-profile appearance
- Precisely sized under-head length and threading ensure proper engagement and efficient torque transfer to the flexplate
- Professional-grade sealing with Loctite 262 or equivalent is recommended to prevent loosening over time
- Replacing the bolts when installing a new flexplate is advised, as factory bolts can fatigue and lose clamping force

- Ensure threads are clean and free of debris before installation for accurate torque readings
