Import Brass Rivet Nuts/ Insert Nuts — Buy in Bulk from Supplier in China

Guangzhou Yinglai Hardware Product Co., Ltd. supplies brass rivet nuts and insert nuts in three head profiles: flat head, countersunk head, and small countersunk head. The threaded inserts cover metric sizes M3 through M12, with UNC thread pitches including 6-32, 8-32, 10-32, 1/4-20, 5/16-18, 3/8-16, and 1/2-13. The body configurations include plain shank, grooved, and hexagonal (or semi-hexagonal) columns for anti-rotation in the host material. The supplier lists carbon steel, aluminium, stainless steel, and brass as available base materials, with this specific offering being brass construction.

Brass rivet nuts provide inherent corrosion resistance and moderate strength suitable for non-structural fastening in electrical enclosures, marine hardware, and decorative metalwork. The alloy typically contains 60-70% copper with zinc balance, offering good machinability and thread-forming characteristics. Head style selection depends on flush-mount requirements: flat heads suit general applications, countersunk heads achieve flush surfaces in thinner panels, and small countersunk heads minimise protrusion in space-constrained assemblies. The grooved or hexagonal shank variants resist torque-out under clamp load, while plain shank suits softer substrates where thread engagement alone suffices.

These insert nuts serve manufacturers of sheet metal fabrications, automotive aftermarket parts, electronics chassis, and furniture hardware. Buyers typically specify thread size, grip range, head style, and shank type to match their panel thickness and installation tooling. Brass construction suits applications where magnetic interference must be avoided or where atmospheric corrosion resistance exceeds carbon steel capabilities. The supplier offers multiple thread standards and imperial/metric coverage, suggesting capacity for mixed-volume production. Confirm material certification, exact grip range per size, and whether installation mandrels are supplied or sourced separately.

Guangzhou Yinglai Hardware Product Co., Ltd. operates from Guangdong Province in Guangzhou, China, a region with dense metalworking and fastener manufacturing infrastructure. The supplier holds a Harbor trust tier on the platform, though the response rate shows 0.00% with zero recorded average response hours. This indicates no active engagement data is available through the platform messaging system. The company lists a diversified product range spanning carbon steel, aluminium, stainless steel, and brass fasteners, suggesting a trading or multi-material manufacturing model rather than single-material specialisation.

The available profile lacks detail on years in operation, factory certification, export licence status, or specific quality management systems. No stated MOQ, price band, or sample policy appears in the source data. Buyers should verify directly whether the supplier manufactures brass rivet nuts in-house or sources from subcontracted workshops, and whether they offer material test certificates or dimensional inspection reports. The broad thread size coverage and multi-material capability suggest either substantial inventory or flexible production scheduling.
