Frequently Asked Questions
What grade are HeSen Track Roller Bolts manufactured to?
HeSen Track Roller Bolts are manufactured to Grade 10.9 and Grade 8.8 standards using premium alloy steel. This ensures high tensile strength and resistance to shearing or deformation even under the extreme loads typical in excavator and bulldozer undercarriage systems.
Which excavator brands are these track roller bolts compatible with?
These bolts are compatible with a wide range of leading heavy equipment brands, including Komatsu, Caterpillar (CAT), Hitachi, Kobelco, Volvo, and Hyundai, among others. They are machined to OEM dimensions to ensure a seamless fit across different models.
How does the black oxide coating protect the bolts?
The black oxide coating provides a durable surface treatment that significantly reduces the risk of rust and corrosion. This is especially important for undercarriage components that are constantly exposed to mud, water, and abrasive materials on construction sites and mining operations.
Do these bolts loosen under heavy vibration?
No. HeSen Track Roller Bolts feature precision rolled threads that are specifically designed to create a tight, vibration-resistant connection. This prevents loosening during continuous heavy-duty operation, reducing the need for frequent re-torquing and maintenance downtime.
What quality testing do HeSen fasteners go through?
Every HeSen fastener undergoes rigorous quality control testing that covers hardness verification, tensile strength measurement, and dimensional accuracy inspection. All bolts are required to meet international standards before leaving the factory, ensuring they deliver the safety and longevity that heavy machinery applications demand.
Can these bolts be used on crawler cranes as well as excavators?
Yes. In addition to excavators and bulldozers, HeSen Track Roller Bolts are suitable for use on crawler cranes and other tracked heavy machinery. Their OEM-matched dimensions and high-grade alloy steel construction make them a reliable choice for any undercarriage fastening application requiring maximum strength and durability.
