Frequently Asked Questions
Q1
What grade of steel are HeSen Track Roller Bolts made from?
HeSen Track Roller Bolts are manufactured from premium alloy steel in Grade 10.9 and Grade 8.8, providing exceptional tensile strength and resistance to shearing and deformation under the heavy loads common in excavator and bulldozer operations.
Q2
Which excavator brands are these track roller bolts compatible with?
These bolts are compatible with a wide range of leading heavy machinery brands, including Komatsu, Caterpillar (CAT), Hitachi, Kobelco, Volvo, and Hyundai, among others. They are machined to OEM dimensions for seamless fitment.
Q3
How does the black oxide coating protect the bolts?
The black oxide coating creates a durable surface treatment that significantly reduces oxidation and rust formation. This makes the bolts well-suited for use in muddy, wet, and highly abrasive construction environments where standard fasteners would quickly corrode.
Q4
Why are rolled threads important for track roller bolts?
Rolled threads are formed through a cold-forming process that increases the thread's surface hardness and fatigue resistance. This produces a tighter, more vibration-resistant fit compared to cut threads, significantly reducing the risk of bolts loosening during continuous heavy-duty operation.
Q5
What types of machinery can use these track roller mounting bolts?
These bolts are designed for tracked heavy machinery, including excavators, bulldozers, and crawler cranes. They serve as undercarriage fasteners to secure the bottom rollers on track frames, which are critical components for the machine's mobility and stability.
Q6
What quality testing do HeSen fasteners undergo before shipment?
Every HeSen track roller bolt undergoes rigorous quality control testing, including hardness testing, tensile strength verification, and dimensional accuracy inspection. All products are required to meet international standards before shipment, ensuring consistent safety and performance for your heavy machinery.
