OEM Custom Hardware Zinc Plated Stainless Steel Flat Head Round Head Deep Hole Semi-tubular Hollow Rivet for Sheet Metal Plastic

Hollow rivets are versatile tubular fastening connectors, customizable in carbon steel, steel, aluminum alloy, stainless steel and brass. Complete standard sizes and non-standard specifications are available as required. Made by precise cold heading forming, these rivets feature smooth surface, uniform wall thickness, easy riveting, simple installation, light weight and good fitting performance. With excellent toughness and stable structure, they stay firmly fastened without loosening, owning great wear resistance and corrosion resistance. They are ideal for connecting thin plates, soft materials and small spare parts, widely used in electronics, leather goods, toys, furniture hardware, nameplate fixing and other fields. We support personalized customization to meet different demands on hardness, anti-rust ability, bearing capacity and appearance, serving as cost-effective hollow tubular fasteners for various industrial assembly.

Solid rivets are one-piece metal rivets with a solid shank and preformed head, classified as high-strength structural rivets. Featuring permanent fastening, vibration resistance, and superior shear strength, they are widely used in heavy-duty applications such as aerospace, automotive, and steel structure projects. Made from premium materials like stainless steel, aluminum alloy, and copper, they undergo precise forging and surface treatment for excellent corrosion resistance, toughness, and stable connections. Available in round, countersunk, and pan head types, they comply with international standards including DIN, AN, and GB. Customization of diameter, length, and surface finish is supported to match varying workpiece thicknesses and load requirements. Installation requires double-sided access; the tail is deformed via rivet gun or press to form an equal-strength double-head joint, ensuring long-term structural safety and stability.

Our customized bicycle bottom bracket nut is designed for high-performance locking and durability. Featuring a serrated flange nut bicycle design, it effectively prevents loosening even under high-intensity vibration during cycling. This crankset locking screw is precision-machined from high-strength steel with professional surface treatments (black oxide or zinc plating) for superior rust resistance. Ideal for universal repairs of center axes and MTB cranksets, it ensures a secure fit and smooth power transfer for your bike.
