Import All Metal Hexagonal Lock Nut — Buy in wholesale FOB from Supplier in China

Hebei Bentley Technology Co.,ltd manufactures all-metal hexagonal lock nuts using automated and self-developed production equipment at its facility in Hengshui City, Hebei Province, China. The lock nut design relies on a deformed or compressed thread section (typically the top threads) to create prevailing torque against loosening from vibration, without auxiliary locking inserts. Standard thread classes for precision fasteners in this category are 6H (internal) mating with 6g (external), though the supplier does not specify exact thread tolerances in the source data. Hexagonal geometry conforms to ISO 4035 or DIN 439 thin-series dimensions for spanner sizing, with the all-metal construction offering temperature resistance beyond nylon-insert alternatives.

Material specification for all-metal lock nuts typically encompasses carbon steel grades such as Class 8 or Class 10 per ISO 898-2, with surface treatments including zinc plating (blue or yellow passivated), hot-dip galvanising, or mechanical zinc for corrosion protection. Stainless steel variants use A2-70 or A4-80 grades for marine or chemical environments. The prevailing torque mechanism depends on controlled interference between nut threads and bolt threads; typical installation torque is 1.5-2 times the standard nut torque for the same size, and reuse is limited because the locking feature degrades with each cycle. Hebei Bentley's source description mentions imported and self-invented equipment with intelligent process management, but does not publish specific material grades, coating thicknesses, or salt-spray test hours.

Applications for all-metal hexagonal lock nuts include railway rolling stock, agricultural machinery, construction equipment, and automotive assemblies where vibration-induced loosening is critical and nylon inserts would fail at elevated temperatures. Buyers in European, Middle Eastern, and Southeast Asian markets import Chinese fasteners under FOB Tianjin or Qingdao terms, with standard export packaging of bulk polythene bags or small cartons on wooden pallets. Payment structures typically involve 30% deposit with balance against copy of BL, though this must be confirmed with Hebei Bentley Technology Co.,ltd directly. The supplier's description states that price depends on size and material, directing buyers to consult for specifics.

Hebei Bentley Technology Co.,ltd is located at Jinghua Building, Shengli Road Newspaper Street, Taocheng District, Hengshui City, Hebei Province 053200, China. The supplier holds a harbour trust tier on the platform, with a 0.00% response rate and zero average response hours recorded. The company profile describes a professional manufacturing system incorporating imported and self-developed equipment, automated production processes, intelligent process management, and large-scale production methods. No founding year, registered capital, employee count, factory floor area, revenue figure, or client list is provided in the source data.

The source description emphasises equipment and production scale but provides no specific certifications (ISO 9001, IATF 16949, or equivalent), no patent numbers for the self-invented equipment, and no detailed product catalogue with dimension tables. The supplier explicitly states that price, material, and dimensions require direct consultation. Buyers should therefore treat initial enquiries as technical qualification discussions rather than expecting immediate quotations. Verification steps should include requesting a factory audit report, equipment list, quality control plan, and sample parts with material certificates before committing to volume orders.
