Hello, Mine Owners and Maintenance Chiefs! I am the supplier who specializes in solving problems like "tracks falling off," "idlers shifting," and "bottom rollers wandering." Today, I’m recommending a "part that seems common but must never be compromised"—the Heavy-Duty Track Bolt for Construction Machinery (Bolt, Part No. 2310076842, Spec M20×80).
Anyone in mining knows our equipment is huge, powerful, and vibrates like crazy. If the bolts on the undercarriage are soft or break, it's not just about losing a part; it means the entire boom, counterweight, or even the cab could fall off! Many cheap bolts on the market look shiny but are made of recycled steel or produced via thread cutting. The threads are shallow, strength is low, they strip under torque, and snap under vibration. Our bolt is specifically engineered for "powerhouses" like mining drills and excavators. It doesn't just tighten; it withstands vibration and resists rust. Choose us to equip your equipment with "bulletproof vests" for every connection point, ensuring stability and peace of mind while working.
High-Strength Alloy Steel: No "Cutting Corners":
Bolts are the lifeline of equipment; material quality is non-negotiable.
Material: We use high-strength alloy steel (e.g., 45# steel, 40Cr alloy steel). This is the same material used for main shafts and gears, offering extreme tensile strength. Don't compare it to ordinary 4.8-grade iron screws; they aren't even in the same league.
Process: Threads are formed using the thread rolling process. They aren't cut away by a lathe but extruded by rolling dies. This preserves the metal flow lines, increasing strength by over 30% compared to cutting, with full, sharp threads that never strip.
Black Oxide Finish: Ignores Mining "Harshness":
Mine environments are brutal—acid rain, mud, urea water—everything attacks metal.
Surface Treatment: The surface undergoes black oxide treatment. This oxide layer acts like an "invisible raincoat" for the bolt, providing strong anti-corrosion ability. Even in damp underground environments or areas frequently exposed to water, they won't rust for years. During disassembly, a wrench removes them easily without seizing or stripping.
Appearance: Dark and glossy, making your equipment look sharp, essential for refurbishments.
Precision Dimensions: Hassle-Free Installation:
Many screws won't fit because of large thread tolerances.
Precision: Our bolt thread tolerances are strictly controlled. Installation is smooth and seamless, without binding or misalignment. When paired with the recommended torque, every tightening is reliable.
Specification: M20×80. This is one of the most common and critical sizes for the undercarriage. Specifically designed to handle connection points requiring massive shear and tensile strength.
Undercarriage Specific: Cures "Loosening, Leaking, Shifting":
Application: Specifically used for fastening bottom rollers, idlers, rock guards, and other major undercarriage components. These areas endure the highest stress and most violent vibrations. Only our high-strength bolts can keep them in check.
Stability: Ensures the undercarriage structure does not shift under heavy impact loads, protecting your travel system's safety.

Exact Match, Ready to Ship: Just provide Part No. 2310076842 or specification M20×80, and we ship immediately. No need to measure threads; hassle-free.
Hardness That Lasts, No Snaps: We guarantee our bolts have sufficient strength. Under torque, they will not strip or snap. If one breaks, come to us for compensation!
Value for Money: We don't sell the cheapest, because they fail, and one snapped bolt can destroy an entire machine. We sell the safest. Do the math: using our bolts means zero breakages per year, saving you repair costs and downtime losses that far exceed the price.
A Quick Tip for the Mechanics:
Brothers, tightening bolts is skilled work and potentially dangerous.
Clean the Threads. Before tightening, thoroughly clean rust and mud from the bolt holes. Otherwise, it might seem tight but isn't seated properly, resulting in insufficient clamping force.
Apply Lubricant. Before tightening, put a bit of engine oil on the threads. This reduces friction, allowing you to achieve the standard preload. Never dry tighten; it looks tight but isn't.
Use a Torque Wrench. For critical locations (bottom rollers, idlers), always use a torque wrench. Don't tighten by feel; too tight causes snapping, too loose causes loosening.
Tighten Diagonally. When installing flanges or covers, always tighten diagonally in stages. Don't pull one side tight first; that causes uneven stress, leading to leaks or deformation. Safe travels home are what matter most!
