Key Features

High Wear Resistance

The hardened surface effectively resists abrasion caused by dust, gravel, rock, and continuous contact between undercarriage components.

Long Service Life

Optimized material selection and controlled heat treatment help maintain mechanical performance over extended operating periods.

High-strength Fastening

Forged alloy steel construction provides excellent tensile strength, ensuring secure fastening even under heavy mechanical loads.

Precision Thread Performance

Accurate thread geometry promotes smooth installation, stable torque application, and consistent preload.

Excellent Fatigue Resistance

Designed to withstand repeated loading cycles without compromising structural integrity, making these fasteners suitable for long-term heavy-duty use.

Corrosion Protection

A durable surface coating helps prevent rust and oxidation, improving reliability in wet, muddy, and outdoor environments.

Product Advantages

The M16×50 bolt and nut assembly helps improve equipment performance by providing:

• Secure fastening performance

Manufacturing Process

Every M16×50 bolt and nut is produced through advanced manufacturing technologies to ensure consistent quality and reliable field performance.

Premium Alloy Steel

Carefully selected alloy steel provides an excellent balance of strength, hardness, and toughness.

Precision Forging

Hot forging improves internal grain structure and enhances resistance to impact and fatigue.

CNC Machining

Modern machining centers ensure dimensional accuracy and thread consistency.

Thread Rolling Technology

Cold thread rolling produces stronger thread surfaces with improved fatigue performance compared to conventional cutting methods.

Heat Treatment

Controlled quenching and tempering optimize hardness while maintaining impact toughness.

Surface Treatment

Protective coatings improve corrosion resistance and help maintain appearance during long-term service.

Quality Control

Every production batch undergoes comprehensive inspection, including:

• Raw material verification
• Chemical composition analysis
• Tensile strength testing
• Hardness inspection
• Thread accuracy measurement
• Dimensional tolerance verification
• Torque and preload testing
• Surface appearance inspection

What are M16×50 bolts and nuts used for?

They are designed to fasten undercarriage components such as track shoes and track links on excavators and bulldozers, ensuring stable and reliable crawler operation.

Why is thread rolling used instead of thread cutting?

Thread rolling forms the threads without removing material, resulting in higher surface strength, better fatigue resistance, and improved thread durability.

Are these fasteners suitable for replacement applications?

Yes. They are manufactured according to OEM dimensional standards and are suitable for maintenance, repair, and aftermarket replacement.

Can customized products be manufactured?

Yes. We provide OEM and ODM services, including custom sizes, thread specifications, strength grades, coatings, packaging, and private branding.
