Shenzhen Zhongzhu Technology Co., Ltd supplies CNC Lathe Machining Parts Screw Rods fabricated from Q235 carbon structural steel, an equivalent of the S235JR grade. Each rod is machined to a dimensional tolerance of ±0.01 mm and is offered with a free surface finish as listed in the source description. The supplier states a minimum order quantity of 3 200 pieces, with sizes produced according to the customer’s detailed drawing.
Q235 steel is a standard low‑alloy structural material widely used for fasteners, providing a typical tensile strength of 370 MPa and a Brinell hardness around 121 HB. In CNC‑lathe screw rod production, a common surface roughness target is Ra 0.8 µm, although the listed finish is “free”, meaning the part meets the basic machining tolerance without additional coating. Standard heat‑treatment for this grade involves normalising to improve grain structure, which is typical for components that require good machinability and moderate strength. The rods are processed through CNC turning, followed by cleaning and inspection, matching the supplier’s documented process route.
These screw rods are integral to CNC lathe transmission systems, providing linear motion and power transfer in automotive, aerospace and general machinery assemblies. Importers usually arrange bulk freight from the Port of Shenzhen, and the supplier can accommodate FOB or CIF terms upon request. While the listing does not disclose lead time or payment conditions, buyers should ask the supplier to confirm production schedule, packaging details and acceptable payment methods. Verifying the material certification and dimensional inspection report before shipment will help ensure compliance with downstream equipment requirements.

Before placing an order, importers should confirm Shenzhen Zhongzhu Technology’s business licence and request any relevant material certifications, such as a mill test certificate for the Q235 steel. A third‑party factory audit or on‑site visit can provide confidence in the company’s production capability and quality management practices. Obtain a detailed technical data sheet that lists dimensions, tolerance, surface finish and heat‑treatment specifics to ensure the parts meet your engineering requirements.
Bulk shipments are usually dispatched from the Port of Shenzhen, but exact lead times depend on order size and the supplier’s production schedule. Typical lead time for a batch of 3 200 rods ranges from two to four weeks after order confirmation; however, buyers should ask the supplier for a firm delivery date. Common Incoterms offered include FOB Shenzhen and CIF Shanghai; discuss which term best fits your logistics network and negotiate payment terms such as TT or LC that align with your cash‑flow strategy.
Arrange a pre‑shipment inspection to verify that each rod conforms to the ±0.01 mm tolerance and the agreed surface finish. Request the final inspection report, along with the material test certificate and any heat‑treatment documentation, to accompany the commercial invoice, packing list and bill of lading. Keeping these documents on file will facilitate customs clearance and provide a reference point for any post‑delivery quality claims.
