Quanzhou Zhongke Autoparts — Reliable Supplier of High-Strength Track Bolts

Product Description

Track bolts, are specially designed fasteners used primarily in heavy-duty vehicles, construction equipment, and machinery, particularly for fastening track shoes to undercarriage systems in excavators, bulldozers, and other crawler-type equipment. These bolts are designed to withstand significant vibration, impact, and heavy loads during continuous operation in tough working conditions.
Our track bolts are made from high-quality materials such as 40Cr and 35# or 45# steel, which provide excellent tensile strength, wear resistance, and durability. Depending on the application, we adopt cold forging or hot forging processes to ensure optimal mechanical properties and structural integrity. Advanced heat treatment techniques are applied to enhance hardness and fatigue resistance, making them ideal for high-stress environments.
To improve corrosion resistance and prolong service life, we offer a variety of surface finishes including zinc plating, phosphating, black oxide, and electrophoresis. These treatments not only provide protection against rust and wear but also ensure compatibility with harsh weather and abrasive field conditions.
Our track bolts are available in multiple diameters and thread pitches, and can be customized according to customer drawings or technical requirements. Each product undergoes a strict quality inspection before delivery, ensuring consistent performance and reliability.

We are committed to offering:
High-strength bolts with certified material and treatment
Competitive pricing and fast delivery
Customized solutions for specific machinery and usage conditions
