Metric 8.8 Flange Bolts are designed with an extensive surface area beneath the head, functioning similarly to a washer. These bolts are coated with yellow zinc, enhancing their resistance to corrosion, making them well-suited for both indoor environments and industrial settings. With a heat treatment process, Class 8.8 fasteners achieve a level of strength comparable to that of Grade 5 fasteners. They boast a tensile strength of 800 MPa, approximately 118,000 psi, which is similar to SAE Grade 5 standards. The head of these bolts is marked with an "8.8" to denote their class, and they are constructed from medium carbon steel.
