Import 304 Stainless Steel Blind Rivet Nuts — Buy in Bulk from Supplier in China

These 304 stainless steel blind rivet nuts are threaded mechanical fasteners designed for installation into sheet metal, tubular, or box-section materials where access is limited to one side. The product range from Guangzhou Yinglai Hardware Product Co., Ltd. includes flat head, countersunk head, and small countersunk head profiles, with body styles encompassing plain shank, grooved shank, and hexagonal (including semi-hexagonal) configurations. Thread sizes span metric coarse threads from M3 through M12 and unified imperial threads from 6-32 UNC through 1/2-13 UNC, covering standard sheet metal and structural assembly requirements in both European and North American equipment markets.

Manufactured from austenitic stainless steel grade 304, these rivet nuts offer corrosion resistance suitable for outdoor, marine-adjacent, and food-processing environments where carbon steel or zinc-plated alternatives would fail. The 304 material provides nominal 205 MPa yield strength and 520 MPa tensile strength in the annealed condition, with work hardening during the riveting process increasing local strength. Head styles determine flush or protruding installation, while grooved or hexagonal bodies resist rotation under torque load. Typical grip ranges vary by diameter and body length, though the supplier does not list specific grip dimensions, so buyers should confirm minimum and maximum sheet thickness compatibility for each size.

Applications include enclosure manufacturing, automotive assembly, HVAC ductwork, signage, and marine fittings where removable threaded anchors are needed in thin-walled materials. The blind installation method (access from one side only) reduces assembly labour compared to weld nuts or tapped holes. B2B purchasers should verify thread class (typically 6H metric or 2B UNF/UNC), body diameter, and head diameter against their hole preparation tooling. Guangzhou Yinglai Hardware Product Co., Ltd. also references carbon steel, aluminium, and brass alternatives in their portfolio, suggesting multi-material sourcing capability for buyers with mixed fastener requirements.

Guangzhou Yinglai Hardware Product Co., Ltd. is based in Guangzhou, Guangdong Province, China, within the Pearl River Delta manufacturing corridor. The supplier holds a harbor trust tier on the platform, though its response rate is recorded at 0.00% with no average response time data available. This communication gap means buyers should initiate contact early and allow for potential delays in quotation or sample provision. The company's product focus on blind rivet nuts in multiple materials and head styles suggests specialisation in fastener manufacturing or dedicated trading with established OEM relationships.

The supplier's address in Guangzhou places it near major container ports (Nansha, Shenzhen) with established export logistics for hardware and fastener shipments. No information is provided about factory ownership, ISO 9001 certification, or production capacity, so buyers should request quality system documentation and factory audit reports if planning volume orders. The mention of carbon steel, aluminium, and brass alternatives alongside 304 stainless indicates either in-house multi-material capability or consolidated sourcing from partner factories. Verify with Guangzhou Yinglai Hardware Product Co., Ltd. whether they manufacture 304 rivet nuts directly or source from subcontracted cold-heading and machining facilities.
