Manufacturing Process
The production process ensures both structural reliability and dimensional accuracy:
Raw Steel Rods
High-quality 40Cr steel rods are selected and precision cut to length before hot forging.
Hot Forging & Head Shaping
Using red-hot steel billets, the bolt heads are formed through controlled press forging, ensuring structural consistency and mechanical strength.
Pre-Thread Machining
After head shaping, each bolt undergoes pre-machining to prepare for threading, with critical dimension control.
Inspection & Final Packaging
All bolts, nuts, and washers are dimensionally inspected, surface-treated, and packed as kits.
