Specialized Design: Automotive hexagonal nuts are specifically engineered for securing connections in automotive manifolds, piping systems, muffler interfaces, and flanges. They deliver reliable clamping force under the sustained extreme temperatures and intense vibrations inherent in engine systems
Precision Dimensions: Hex nuts are manufactured strictly to the M8×1.25 thread standard with precise dimensions (hex width 0.5 inches, height 0.25 inches, inner diameter 0.34 inches). Please verify the thread specifications of your vehicle's original nuts before purchasing
Hexagonal Design: The hexagonal nut features a standard hexagonal shape for easy tightening with open-end wrenches or sockets. The flange design at the nut's base increases the contact area with the connecting component, facilitating more even distribution of preload force
10 Pieces: Each package contains 10 premium hexagonal nuts (OEM reference part number A1201420072). This ample quantity not only suffices for a complete manifold or pipe repair but also provides spares for future maintenance or replacement of lost nuts
Durable Material: The M8 x 1.25 hex nut body is forged from high-strength iron, delivering exceptional mechanical strength and tensile resistance. Its copper-plated surface significantly enhances rust resistance, enabling it to withstand harsh environments
