Manufacturing Process
The production process ensures both structural reliability and dimensional accuracy:
Raw Steel Rods
We begin with high-quality 40Cr steel rods, inspected for internal integrity and dimensional accuracy.
Hot Forging & Head Shaping
Using heat treatment and forging machines, the rod ends are shaped into heads (hex or custom).
Pre-Thread Machining
After head shaping, each bolt undergoes pre-machining to prepare for threading, with critical dimension control.
Inspection & Final Packaging
Finished bolts, nuts, and washers are measured, tested, and packaged in customizable sets.
Applications & Fitment
Customized bolts and nuts are widely used for:
- Bucket teeth and adapters
- Undercarriage assemblies (track shoes, rollers, sprockets)
- Cylinder mounting
- Counterweight attachments
- Structural joints and reinforcements
No matter how demanding your equipment or working condition, we can match or exceed OEM specifications.
