1. The bolts are designed to metric M10 x 1.25 specifications, effectively preventing exhaust manifold loosening and leakage during engine operation while ensuring exhaust system sealing integrity2. The bolt kit is crafted from high-strength carbon steel, offering high hardness and load-bearing capacity, suitable for harsh automotive operating environments3. The bolts include both the bolt and a specialized spring. The flange surface increases the load-bearing area

• Premium Material: The bolt kit is crafted from high-strength carbon steel, offering superior hardness and load-bearing capacity. It withstands the high-temperature environment of the engine exhaust system. The surface undergoes rust-proof treatment, ensuring long-term use without rusting or breaking.
• Standard Specifications: The exhaust pipe bolts are designed to metric M10×1.25 specifications with high thread precision. They match the mounting holes on most vehicle exhaust manifolds, ensuring a tight connection and preventing installation difficulties or leaks caused by dimensional deviations.
• Key Features: The unique thread design of the exhaust flange bolts delivers powerful clamping force, effectively preventing exhaust manifold loosening and leaks during engine operation. This ensures exhaust system sealing, enhancing engine performance and fuel efficiency.
• Complete Set: Each exhaust bolt includes a bolt and specialized spring. The enlarged flange surface increases load-bearing area for enhanced connection stability. The spring washer provides elastic compensation to absorb vehicle vibrations during operation, preventing bolt loosening.
• Easy Installation: Equipped with spring mechanisms, these intake manifold bolts enable quick and straightforward installation. Simply align with the exhaust pipe and tighten the bolts. You will receive two intake manifold bolts with spring mechanisms, each measuring 2.9 " in total length with a stud diameter of 0.82 ".
