The H7 Clamping Ring supplied by Zhejiang Invitech Precision Technology Co., Ltd is a ferritic stainless steel adaptor designed for H7 PX26D automotive headlamp assemblies. It is machined from SUS 430 stainless steel and conforms to strict dimensional tolerances of 15 mm outer diameter (±0.1 mm) and 4.5 mm height (±0.2 mm). An eccentricity of 0.8 mm with a tolerance of ±0.06 mm is maintained to ensure centred lamp positioning. The component passes an outgassing test, confirming suitability for sealed lighting housings.
SUS 430 offers good corrosion resistance in automotive environments and is commonly selected for cost‑effective lighting hardware. While the supplier offers custom finishes, the standard product is supplied in a mill‑finished condition that meets typical automotive grade standards. In the metal‑stamping industry, such adaptors are usually produced by precision stamping followed by secondary machining to achieve the required tolerances. Typical industry practice also includes a surface roughness of Ra ≤ 1.6 µm to minimise light scattering.
The ring is used by headlamp manufacturers, OEM parts distributors and aftermarket refurbishers who require reliable lamp retention under temperature extremes. Zhejiang Invitech ships the rings in cartons of 5 000 pieces, facilitating bulk handling for large‑scale production lines. Buyers should confirm the accepted Incoterms, payment schedule and any required certification before placing an order. The supplier’s harbour‑level trust tier indicates a verified business with a documented response record, though the current response rate is zero.

Before placing an order, importers should request the supplier’s material certification for SUS 430 and verify the dimensional tolerance data against their design drawings. Confirm that the outer‑diameter, height and eccentricity values meet your assembly requirements, and ask for a sample if possible. Checking the supplier’s harbour‑level verification status and any available audit reports can further reduce risk.
Logistics for the clamping ring are not detailed in the listing, so buyers need to ask the supplier which Incoterms (FOB, CIF, etc.) are offered and what the expected lead time is for a 5 000‑piece carton. Payment terms such as T/T, L/C or open‑account should be clarified in advance. Because the response rate is currently zero, allow extra time for communication and consider a trial order to gauge responsiveness.
Quality assurance typically includes an outgassing test, but buyers may also request additional inspections such as dimensional verification with a coordinate‑measuring machine and a surface‑roughness check. Specify any required third‑party inspection agencies and request the inspection report before shipment. Obtaining the supplier’s compliance documents, even if only typical, helps ensure the rings meet automotive grade standards.
