Key Features
Superior Strength: Made from Grade 8.8 steel, these bolts can withstand tensile loads up to 80 kN and yield loads up to 64 kN. This ensures they can handle the intense stress and strain encountered during excavator operations, reducing the risk of breakage and failure.
Corrosion Resistance: The black oxide coating provides an extra layer of protection against corrosion. This is particularly beneficial for equipment used in harsh environments where exposure to moisture, chemicals, and dirt is common. The stainless steel material further enhances the bolt and nut's ability to resist rust and corrosion, prolonging their service life.
Precision Fit: Manufactured to exacting standards, the No. 303 - 9441 Hex Bolt is specifically designed to fit Caterpillar excavator components. Its precise dimensions and threading ensure a secure and reliable connection, minimizing play and wear on connected parts.
