Collection: Class 8.8 Serrated Flange Bolts

Class 8.8 serrated flange bolts are high-strength fasteners designed to provide a secure grip and prevent loosening in applications subject to vibration or dynamic loads. The serrated flange under the bolt head enhances friction and distributes the load evenly, eliminating the need for a separate washer. These bolts are commonly used in automotive, industrial, and structural settings, offering durability and reliability in demanding environments.
