Import Bolt Rivet Nut — Buy in wholesale FOB from Supplier in Taiwan

Top Screw Metal Corp. produces bolt rivet nuts in stainless steel 302/304 (A2/18-8), 316 (A4/18-10), steel, aluminum 5056/6061 and brass C2600, with unified thread 2A/21 per ASME B1.1 and metric 6g/21 per ASME 1.21M. The fastener combines a bolt pre-installed with a blind rivet nut, eliminating the need for separate screw insertion after riveting. Thread specifications cover both UNC and ISO dimensions, with additional UNF fine threads available on request. Grip range varies with parent material density and actual hole size, so trial installations are recommended to determine optimum grip for each application.

The 302/304 stainless steel grade offers general corrosion resistance suitable for most environments, while 316 (A4/18-10) provides enhanced resistance to chlorides and marine atmospheres. Aluminum 5056/6061 delivers a lightweight alternative with good saltwater resistance, and brass C2600 suits applications requiring electrical conductivity or compatibility with copper alloys. Steel variants provide maximum shear and tensile strength for structural assemblies. The pre-combined bolt and rivet nut design ensures the fastener will not loosen from vibrating objects once installed, a critical advantage over conventional threaded assemblies in mobile equipment.

These fasteners are used where welding is impractical or prohibited, including sheet metal enclosures, vehicle bodies, railway carriages, and aircraft interior panels. The high torque capacity and strong threads suit combination applications needing rigid binding support. Typical buyers include OEMs in automotive, electronics, HVAC, and aerospace sectors, plus metal fabrication shops serving these industries. Packaging and minimum order quantities should be confirmed directly with Top Screw Metal Corp., as should lead times for non-standard materials or fine thread variants.
