China Flange Nut Manufacturer, Supplier, Factory

Made from premium-grade materials QBH Flange Nut are specifically designed to resist vibration, corrosion, and other forms of wear and tear, ensuring long-lasting performance in harsh environments. The flange design incorporates a wide, flat base with serrated edges, which provides a larger bearing surface and prevents the nut from loosening due to axial or shear loads. The built-in washer eliminates the need for separate washers, reducing the number of parts and assembly time.


Not only do QBH Flange Nut improve joint stability and safety, but they also offer flexibility in installation. They are available in a variety of sizes and shapes, including hexagonal, square, or round, to fit different bolts, studs, or threaded rods. Some models feature self-locking properties, such as nylon inserts or prevailing torque, which eliminate the need for additional locking mechanisms and reduce the risk of over-tightening.


Whether you are building a bridge, repairing a vehicle, or assembling a furniture piece, QBH Flange Nut are an excellent choice for your fastening needs. QBH Flange Nut can be used in combination with other fasteners, such as washers, lock washers, or bolts, to create a secure and durable joint.
