Import Aluminum Blind Rivet Nuts/Insert Nuts M6 — Buy in Bulk from Supplier in China

Guangzhou Yinglai Hardware Product Co., Ltd. manufactures aluminum blind rivet nuts in M6 size with multiple head and body configurations for sheet metal assembly. The source confirms flat head, countersunk head, and small countersunk head options, with column types including plain (park rod), grooved, and hexagonal (semi-hexagonal) designs. M6 corresponds to a nominal 6 mm internal thread diameter, though the source does not state pitch (standard coarse pitch is 1.0 mm for M6). Buyers should confirm thread class and pitch, as fine pitch variants (M6x0.75) exist for specific applications requiring finer adjustment or greater thread engagement depth.

Material options extend beyond aluminum to carbon steel and stainless steel for the small countersunk head insert variant, per the source data. Aluminum rivet nuts typically use 5052, 5056, or 6061 alloy for balance of corrosion resistance, strength, and mandrel pull-out performance during installation. The source does not specify alloy grade, so buyers should request confirmation. Head types determine surface flushness: flat heads leave a visible flange, countersunk heads sit flush in chamfered holes, and small countersunk heads reduce footprint for tight spaces. Grooved and hexagonal bodies resist rotation in the host material better than plain cylindrical designs.

These fasteners suit applications in automotive body panels, HVAC equipment, electronics enclosures, and general sheet metal fabrication where access is limited to one side of the workpiece. The M6 size supports moderate load requirements in aluminum, though steel or stainless variants handle higher shear and tensile loads. The source lists additional metric sizes (M3 through M12) and imperial threads (6-32 through 1/2-13), indicating broader manufacturing capability. No MOQ, pricing, or lead time is provided, so buyers must confirm these directly with Guangzhou Yinglai along with any required thread locking features or specialty coatings.

Guangzhou Yinglai Hardware Product Co., Ltd. is located in Guangdong Province, Guangzhou, China, with the specific district or industrial zone not stated in the available profile. The supplier carries a 'harbor' trust tier classification with a 0.00 percent response rate and zero average response hours recorded, indicating limited or no recent buyer engagement data through this channel. The company name suggests specialization in hardware products, and the listing focuses on blind rivet nuts across multiple materials, sizes, and head configurations, though no founding year, facility size, or employee count is disclosed.

The source description presents Guangzhou Yinglai as a manufacturer offering aluminum, carbon steel, and stainless steel variants with comprehensive size coverage in both metric and imperial threads. There is no mention of specific certifications (such as ISO 9001, IATF 16949 for automotive, or RoHS/REACH compliance), major client references, or export market experience. Buyers should verify whether Guangzhou Yinglai operates its own production facility or functions as a trading company, request factory audit reports if possible, and confirm quality control procedures for thread forming and dimensional inspection.
