NUT

The PAI Industries 40115 Nut is a precision-engineered fastener designed to provide superior holding power and thermal stability in heavy-duty applications. Commonly used on turbocharger mounts, exhaust manifolds, and engine assemblies, it’s manufactured from hardened steel and treated with a high-temperature, corrosion-resistant coating.



PAI’s high-tolerance manufacturing ensures this nut maintains torque retention and thread integrity even in extreme vibration and heat environments, making it ideal for long-haul trucks and fleet vehicles.



This nut is compatible with several Cummins, Detroit Diesel, and Volvo engine platforms and is often paired with turbocharger studs (like PAI 40112 and 40113). It’s built to OEM quality and trusted across maintenance shops for dependable installation and long service life.
