M3 x 6mm Zinc-Plated Carbon Steel Pan Head Hollow Tubular Rivets with Cap for Leather — OEM/ODM

Semi-hollow rivets (also known as semi-tubular rivets) are lightweight fasteners with a solid head and hollow tail, balancing the strength of solid rivets and the easy installation of hollow rivets. Manufactured by cold heading, they are available in stainless steel, carbon steel, aluminum and copper, with sizes M1.2–M10 compliant with GB/T 873/874/875 standards. The hollow tail deforms easily during riveting for tight filling, ensuring secure fastening with low installation force. Ideal for thin sheets and soft materials in luggage, electronics, furniture and automotive interiors, they support custom head types, dimensions and finishes (zinc plating, anodizing) for diverse applications.

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.

Micro screws, also known as miniature screws, are precision fasteners with a diameter ranging from 0.3mm to 5mm, designed for space-constrained and high-precision assembly scenarios. Our custom micro screws adopt advanced Swiss CNC machining technology, with tight tolerances of ±0.003mm, ensuring stable performance and perfect fit in various delicate equipment. We offer diverse customization options for materials, head types, thread pitches and surface treatments, covering industries such as electronics, medical devices, aerospace and watchmaking. As a professional custom micro screws manufacturer, we adhere to ISO 9001 and ISO 13485 standards, providing high-quality, reliable micro fasteners to global customers.

Made of high-quality carbon steel and stainless steel with precise thread structure, these lock nuts deliver excellent anti-vibration and anti-loosening performance to prevent loosening during equipment operation.
