Profleet Exhaust Manifold Taperlock Stud - 12PK - M10x1.5x85mm High Temperature Fastener for CT C12 C13 Diesel Engines, Heavy Duty Trucks, Replaces 1163715

Engineered for Extreme Heat and Security: The 1163715 Exhaust Manifold Taperlock Stud. This is twelve genuine 1163715 Taperlock Stud, a critical, high-temperature fastener designed by Caterpilar for its heavy-duty diesel engines. This stud's primary function is to securely mount the exhaust manifold, a component subjected to immense heat, vibration, and thermal expansion. The 1163715 stud is a fully threaded metric fastener with an M10 x 1.5 mm thread pitch and an overall length of 85 mm. Its distinguishing feature is the Taperlock design, which locks the stud into the cylinder head threads, ensuring it remains properly seated during manifold assembly and throughout the engine's service life. This locking action is vital for preventing manifold leakage and failure. This stud is commonly used on some of the most popular CT engines found in commercial trucks, construction equipment, and motor graders.
