Import Automatic Nut Tapping Machine — Buy in Bulk from Supplier in China

The automatic nut tapping machine from Hebei Hardwork Machinery Co., Ltd. is built for hexagon nut production across M6 to M20 sizes, with a threading mechanism that can be customised to specific nut geometries. The unit handles bulk output with a focus on repeatability across long production runs, reducing the manual intervention normally associated with tapping operations. Its frame is designed for continuous industrial use, with hardened tooling stations that maintain thread profile accuracy over thousands of cycles.

The machine processes carbon steel, alloy steel and stainless steel blanks, with typical spindle speeds adjusted through a variable frequency drive to match material hardness and tap diameter. Thread pitch accuracy is governed by the relationship between lead screw geometry and spindle rotation, with standard tolerances held to ISO metric coarse and fine thread classes. Tool changers can be configured for multi-start or left-hand threads where the application demands, though buyers should confirm thread form compatibility with their existing gauge systems.

Buyers in automotive fastener supply chains, agricultural machinery assembly and structural bolt manufacturing represent the core market for this equipment. The M6 to M20 range covers the bulk of construction and mechanical engineering nut sizes used in ISO and DIN standard assemblies. For import, confirm whether the control system operates on 380V three-phase supply or requires local voltage adaptation, and clarify whether Hebei Hardwork Machinery supplies tap holders as standard or as optional accessories.

Hebei Hardwork Machinery Co., Ltd. is located on Yuhua Road in Shijiazhuang, Hebei Province, with postal code 050000. The supplier holds an imported tier classification on the platform and is designated under the harbor trust tier, which represents a baseline verification level without additional third-party audit documentation.

The company profile does not disclose factory size, year of establishment, annual revenue, or specific client references. No ISO, CE or other certification numbers are independently verified in the available data, and any claim to such marks should be confirmed directly with the supplier through document request. Buyers should treat the supplier address as the primary contact point and verify whether Hebei Hardwork Machinery operates as a manufacturer, trading company, or hybrid entity before committing to tooling customisation or spare parts agreements.
