About Ningbo Good Hardwares Co., Ltd. - CNC Machines & Spare Parts Supplier in China

Ningbo Good Hardwares Co., Ltd. is based in China and lists five active products. The catalogue covers CNC Machines & Spare Parts as well as standard fasteners such as nuts, screws, and pins. The listed items include a CNC turned axle sleeve, non‑standard CNC turn nuts, CNC milling screw, CNC milling machining shaft, and CNC pins with hole. The supplier’s trust tier is classified as "harbor" indicating a certain level of platform verification. All products are designated under the broad categories of machine tool components and metal fasteners. The CNC turned axle sleeve is described as medium carbon steel or alloy steel, specifically grades SCM415 or 4140, and is recorded under HS code 8483.60, which covers parts for machine tools. The remaining items - turn nuts, milling screw, machining shaft and pins with hole - are presented without explicit HS codes but fall within the typical HS chapter 73 for metal fasteners and machine parts. The product set reflects a focus on precision‑machined components used in automated equipment and assembly lines.

Product Range and Specialties of Ningbo Good Hardwares Co., Ltd.

The catalogue lists a CNC turned axle sleeve fabricated from medium carbon steel grades SCM415 or 4140, materials commonly selected for their tensile strength of approximately 800‑1000 MPa and hardness around 30‑35 HRC after heat treatment. The sleeve dimensions are not specified, but standard CNC‑produced sleeves often meet ISO 2768 tolerance class ‘f’ and surface finish Ra 1.6 µm. The other four items - non‑standard CNC turn nuts, CNC milling screw, CNC milling machining shaft and CNC pins with hole - are typical fasteners and shafts produced by CNC turning, usually supplied in stainless steel or alloy steel with thread standards such as ISO metric (M) or UNC/UNF. In the CNC fastener market, buyers commonly request grades such as 8.8, 10.9 for bolts, or equivalent hardness for nuts, and expect mill test reports confirming chemical composition and mechanical properties. Screws for milling machines are frequently supplied in grades 12.9 or alloy steel with tensile strength above 1200 MPa, and pins are often sized between 5 mm and 30 mm in diameter with drilled holes toleranced to ±0.05 mm. These specifications align with the typical requirements of automotive, aerospace, and general manufacturing sectors.

Trade and Export Information - Ningbo Good Hardwares Co., Ltd.

China is a global exporter of CNC‑machined components and metal fasteners, with major outbound shipments directed to the United States, Germany, Japan, and Southeast Asian manufacturing hubs. Products classified under HS chapter 84 (machine tool parts) and chapter 73 (iron and steel products) are subject to customs inspections that verify material certificates and compliance with destination country standards such as ISO 9001 quality management or CE marking for the EU market. Export shipments of CNC‑turned parts are typically packed in wooden crates or bulk cartons, secured on standard 20‑foot or 40‑foot containers with anti‑corrosion coating applied. Buyers often require a Mill Test Report (MTR), a Material Safety Data Sheet (MSDS), and compliance documentation for RoHS or REACH when the destination is the EU. Common Incoterms used include FOB Ningbo port and CIF destination ports, allowing the buyer to manage freight and insurance according to their logistics preferences.

Sourcing from Ningbo Good Hardwares Co., Ltd. - Buyer Guidance

Potential buyers should request a detailed product data sheet that includes material grade, heat‑treatment condition, hardness range, and dimensional tolerance. For the axle sleeve, confirming the steel grade (SCM415 or 4140) with a certified MTR helps validate tensile strength and impact resistance. For fasteners, ask for thread profile drawings and compliance with ISO metric standards or applicable DIN specifications. Obtaining a physical sample of the CNC‑turned sleeve or a batch of nuts before full order is standard practice to assess surface finish and dimensional accuracy. Buyers should also verify that the supplier holds ISO 9001 certification or can provide evidence of third‑party inspection, and confirm packaging details such as pallet configuration (e.g., 12 × 12 × 12 inches per box) and container loading plan to avoid damage during transit.

What material grades are used for the CNC turned axle sleeve?

The sleeve is manufactured from medium carbon steel, specifically grades SCM415 or 4140, which provide tensile strengths around 800‑1000 MPa and a typical hardness of 30‑35 HRC after heat treatment.

Which HS code applies to the CNC turned axle sleeve?

The axle sleeve is listed under HS code 8483.60, the classification for parts and accessories of machine tools.

What certifications are commonly required for CNC‑machined fasteners from China?

Buyers usually request ISO 9001 quality‑management certification, a Mill Test Report for material verification, and, for EU shipments, CE marking or RoHS compliance documentation.

How are the CNC turn nuts and milling screws typically sized?

Non‑standard CNC turn nuts and milling screws are produced to metric thread standards (e.g., M6‑M24) with tolerance class f per ISO 2768 and surface finish Ra 1.6 µm, unless a custom specification is supplied.

What packaging format is used for bulk shipments of these components?

Items are commonly packed in bulk cartons or wooden crates, stacked on standard Euro pallets, and loaded into 20‑foot or 40‑foot containers with moisture‑resistant liners.

Which markets import CNC‑turned components from China most frequently?

The United States, Germany, Japan, and emerging manufacturing regions in Southeast Asia are the primary import destinations for Chinese CNC‑machined parts and metal fasteners.

What documentation should be requested before placing an order?

Request a Mill Test Report, material safety data sheet, product drawings with tolerance specifications, and proof of any relevant ISO or CE certifications to ensure compliance with the buyer’s quality and regulatory requirements.
