Import Brass Insert Nut — Buy in wholesale FOB from Supplier in China

Brass insert nuts from Suzhou Hogreat Metal Product Co., Ltd. are precision-engineered threaded fasteners manufactured from brass CW614N (CuZn39Pb3), also known as CZ121 free-cutting brass, a leaded brass alloy containing approximately 57-59% copper, 2.5-3.5% lead, remainder zinc. These components feature internal threads produced via automatic lathe processing with subsequent tapping, designed for press-fit or moulded-in insertion into plastic, wood, or soft substrates to create wear-resistant metal threads. The factory produces these to customer drawings or samples, with hardness testing machines, projectors, slide calipers, micrometers, and thread gauges used for dimensional verification.

The CW614N / CZ121 material grade offers excellent machinability due to its lead content, enabling precise thread forms and consistent knurled or smooth cylindrical outer surfaces for secure retention in host materials. Standard surface treatment is cleaning, leaving a bare brass finish suitable for visible applications or further plating if specified. Typical outer geometries include straight, diamond, or helical knurl patterns to resist rotational and pull-out forces when embedded. Thread standards follow customer drawings or samples rather than fixed catalogues, allowing metric or imperial thread forms depending on end-use requirements.

Primary applications span furniture assembly (hinge and panel connections), automotive interior trim and dashboard components, electronics enclosures and handheld device housings, plus general industrial equipment where repeated fastening cycles are expected. Buyers are typically OEMs in plastics moulding, contract furniture manufacturers, and automotive tier suppliers requiring reliable thread inserts for assembly. The supplier indicates capability for custom specifications and ODM/OEM orders, with 100% inspection before shipment under ISO9001 and ZDHY certification frameworks. Buyers should confirm exact MOQ, lead times, Incoterms, and whether tooling costs apply for non-standard geometries.

Suzhou Hogreat Metal Product Co., Ltd. operates from No. 3, Shitian Road, Yangcheng Lake Town, Xiangcheng District, Suzhou City, Jiangsu Province, China, postal code 215138. The company's product portfolio extends beyond brass insert nuts to encompass nuts, turning parts, CNC machined components, and fittings, indicating a focus on precision metalworking rather than commodity hardware. The trust tier is classified as harbour, and the response rate shows 0.00 with zero average response hours, which suggests the listing may lack active response data or recent enquiry activity.
