The integrated flange distributes clamping load across the mating surface, making it well suited for fuel system connection points where a secure, leak-resistant joint is required.\u003c\/p\u003e\n\n\u003cp\u003eGrade 8.8 denotes a medium-carbon steel bolt with a minimum tensile strength of 800 MPa and a proof load rating appropriate for demanding mechanical assemblies.
