Frequently Asked Questions
Q
What grade of steel are HeSen Track Roller Bolts made from?
HeSen Track Roller Bolts are manufactured from premium alloy steel, available in Grade 10.9 and Grade 8.8, providing high tensile strength to resist shearing and deformation under heavy operational loads.
Q
Which excavator and machinery brands are these bolts compatible with?
These track roller bolts are compatible with a wide range of leading brands including Komatsu, Caterpillar (CAT), Hitachi, Kobelco, Volvo, and Hyundai, as well as other major excavator, bulldozer, and crawler crane manufacturers.
Q
How does the black oxide coating protect the bolts?
The black oxide coating forms a durable protective layer on the bolt surface, significantly improving resistance to rust and corrosion. This makes the bolts reliable in demanding environments including muddy, wet, and highly abrasive construction sites.
Q
Why are rolled threads important for track roller bolts?
Rolled threads create a stronger thread form compared to cut threads and provide a tighter, more vibration-resistant engagement. This prevents the bolts from loosening during the intense vibrations and impacts typical of excavator and bulldozer operations.
Q
What quality testing do HeSen Track Roller Bolts undergo?
Every HeSen track roller bolt is subject to rigorous quality control testing, including hardness testing, tensile strength verification, and dimensional accuracy inspection, ensuring full compliance with international standards for heavy machinery fasteners.
Q
Are these bolts direct OEM replacements?
Yes. HeSen Track Roller Bolts are machined to exact OEM specifications and strict dimensional tolerances, ensuring a seamless drop-in fit for track rollers and idlers without requiring any modification during installation.
