Product details
Product Overview
Our Class 8.8 Hex Bolts are precision-engineered fasteners designed for demanding industrial environments. Manufactured from medium carbon steel and heat-treated for increased strength, they provide reliable performance in mechanical assemblies, structural frameworks, and heavy-duty machinery.

Standards & Material
These bolts conform to ISO (formerly DIN) specifications and are engineered for dimensional accuracy and tensile strength. Class 8.8 designates medium carbon steel with a minimum tensile strength of 800 MPa and yield strength of 640 MPa, making them ideal for dynamic load applications.

Threading Options
Available in coarse (standard), fine, and extra-fine thread configurations. Coarse threads are widely used for general fastening, while fine threads offer superior vibration resistance, especially in high-speed machinery and precision equipment.

Corrosion Protection
Choose between zinc-plated finish for moisture resistance and black corrosion-resistant coating for enhanced chemical and salt spray protection. For optimal performance, use with matching corrosion-resistant nuts and washers.

Applications
Hex bolts are widely used in mechanical, automotive, construction, and equipment manufacturing industries. They are ideal for securing joints, frames, and mechanical components where strength, durability, and compliance are essential.
