Factory Profile

    Our factory excels in end-to-end quality control covering raw materials to finished goods. We adopt premium compliant steel. All raw materials are fully tested with professional equipment for chemical composition, hardness, toughness, mechanical properties and microstructure before warehousing, to ensure 100% compliance and secure quality at source.

Equipped with modern standardized workshops and full automatic forming lines, we produce precision bolts via cold heading, precision turning, thread rolling, heat treatment and surface treatment. The whole process applies intelligent closed-loop control and standard SOPs to guarantee dimensional accuracy, smooth threads and structural strength. Multi-stage inspections detect and fix manufacturing deviations timely, delivering bolts with stable performance and consistent precision.

We support standard and custom bolt orders, with strong capability for large-volume high-quality mass production.

Finished Product Inspection:

Before finished product shipment, our factory implements a strict full-item inspection process for finished products. With the help of professional laboratory equipment for mechanical testing and metallographic analysis, we comprehensively verify the mechanical properties and comprehensive quality of finished bolts such as tensile strength, compression resistance, wear resistance and corrosion resistance, and all unqualified products will be eliminated and reworked. All qualified finished products are uniformly stored in our intelligent warehousing center for intelligent classification, registration and storage management. Relying on a sound warehousing system and mature supply chain system, we can undertake mass orders for conventional standard bolts and non-standard customized bolts. With efficient shipment efficiency and stable supply capacity, we can quickly respond to order demands of global customers and ensure on-time and high-quality order delivery.

Standardized Packaging Process:

    To avoid bolt collision, wear, corrosion, thread damage and other problems during transportation, our factory adopts a professional and standardized finished product packaging process. According to the specifications, models, sizes of bolts and order requirements, we adopt multi-layer protective packaging methods such as anti-static packaging, moisture-proof and rust-proof packaging, hard cartons and pallet reinforcement for classified packaging. All products will undergo a secondary appearance inspection before packaging to clean surface impurities and oil stains, and be sealed only after confirming no defects. The whole packaging process is standardized with clear and complete marks, clearly indicating product specifications, quantity, batch, quality inspection number and other information. It can not only maximize the integrity of products in the whole process of warehousing, transportation and logistics distribution, but also facilitate customers' receiving verification and inventory management, providing one-stop high-quality supporting shipment services for customers.
