Z1 Replacement Exhaust Bolt & Nut Hardware for all models and most exhausts. The bolt has a M10x1.25 thread pitch with a thread length of 45mm. The prevailing torque lock nut was chosen over the standard serrated flange nut to ensure there is no backing out once this hardware is installed. As well as eliminating the need for any washers or lock washers. Prevailing torque lock nuts are designed to prevent loosening from vibrations by deforming the mated bolt's threads, making them perfect for exhaust hardware. Nissan & Infiniti typically use prevailing lock nuts on exhaust manifolds and catalytic converters due to their high reliability to not back out over time.

Once this hardware is installed, it is not recommended to be reused due to the prevailing nut's locking mechanism deforming.

Includes

• 1 - High Strength Grade 10.9 Zinc-Coated Flanged Bolt
• 1 - Prevailing Torque Lock Nut

Sold as a single bolt and nut.
