Import Bolts — Buy in Bulk from Supplier in China

Ningbo Haitian Hardware & Plastic Co., Ltd manufactures bolts from its facility on Zhongshan Road, Ningbo, Zhejiang Province, China. The product line centres on carbon steel bolts with zinc plated finish for corrosion resistance, positioned for construction, automotive assembly, and machinery fabrication. The source specifies high-grade carbon steel as the base material and multiple dimension options, though exact size ranges and thread configurations are not itemised. The supplier lists both FOB and CIF shipping terms and indicates flexible minimum order quantities without quoting specific numbers.

Carbon steel bolts from the Ningbo region are typically produced from cold-heading quality wire rod, grades such as SWRCH35K or ML40Cr for medium-carbon strength, or 10B21 for alloy bolting. Zinc plating is generally electro-deposited with blue or yellow passivation; typical thickness ranges from 5 to 12 micrometres depending on corrosion class required. The stated high load capacity suggests heat treatment to property classes 8.8 or above, though buyers should verify actual grade and tensile test values. The finish quality, thread rolling precision, and head forming consistency are factors that distinguish Ningbo fastener output within the Chinese manufacturing base.

Buyers include construction firms needing structural connections, automotive tier suppliers requiring consistent torque-tension performance, and machinery builders assembling frames and guards. The zinc plating suits indoor and mild outdoor environments; aggressive atmospheres may need supplemental protection. Because response metrics show zero activity, buyers should confirm current quotation turnaround, whether existing tooling covers their required sizes, and if the supplier holds current ISO registration with scope covering bolt manufacturing.

Ningbo Haitian Hardware & Plastic Co., Ltd is located at Zhongshan Road number 369, Ningbo, Zhejiang, 315040, China. The supplier operates under an imported tier with harbour trust classification. The response rate is recorded at 0.00 percent with zero average response hours, indicating limited or no recent platform engagement. No founding year, employee count, factory floor area, revenue figure, or named clients appear in the source data. The address places it within Ningbo's established hardware manufacturing district, which carries logistical advantages through nearby Beilun Port.

The product focus is industrial-grade bolts for B2B buyers, with emphasis on strength, corrosion resistance, and flexible ordering. ISO certification is mentioned but not substantiated with certificate numbersijverheid numbers or scope details. Buyers should independently verify registration status, audit reports, and whether quality management extends to the bolt production line specifically, as the company name also references plastic products which may indicate diversified manufacturing.
