Clinch Bolts for Thin Sheet Metal and Mechanical Assembly
Clinch bolts provide a permanent, mechanical connection for thin sheet metal components where traditional bolts and nuts cannot be used. Because the bolt embeds into the sheet during installation, the joint becomes strong and vibration-resistant. This makes clinch bolts suitable for automotive panels, electronic housings, appliance manufacturing, and a wide range of industrial assemblies. With a secure fit and clean appearance, clinch bolts offer a practical fastening method for lightweight structures.
Material Options and Surface Finishes
Our clinch bolts come in stainless steel, carbon steel, and alloy steel. These materials deliver high tensile strength and excellent durability. Additionally, several finishes such as plain and zinc-plated coatings help protect the fasteners from moisture and corrosion. As a result, the bolts maintain stable performance even in demanding environments. Because the fasteners lock into the sheet without extra hardware, they help reduce assembly time and simplify production processes.
OEM Customization for Industrial Applications
To meet global industrial requirements, we offer OEM customization for diameter, length, coating, and surface treatment. You may select metric sizes such as M3 to M8 or request special specifications. Furthermore, we provide custom packaging including small cartons and branded bags. Since many customers require multiple deliveries throughout the year, we also support free warehouse storage to ensure stable supply.
