BOLT SPECIFICATIONS

What are Industrial Bolts?

These are precision-engineered threaded fasteners designed to create a secure mechanical joint between components in appliances, industrial machines, and electronic assemblies. As a trusted OEM manufacturer for global leaders like Mitsubishi Electric, we produce a specialized range of industrial bolts from M4 to M12, including hex head bolts, socket head cap screws, hex flange bolts, and specialized weld bolts. We ensure every bolt is manufactured strictly according to JIS and international specifications based on your technical drawings, providing the critical fastening force and structural stability required for high-performance home appliances and industrial automation systems.

Features of Our Quality-Verified Bolts:

Our industrial bolts are characterized by 100% thread accuracy and superior batch-to-batch consistency. By utilizing high-speed optical sorting technology, we ensure every component meets tight dimensional tolerances, effectively preventing costly jams or failures in your automated installation and assembly tools. Additionally, our bolts provide excellent corrosion resistance verified through rigorous salt spray testing, ensuring long-term durability in the high-humidity environments typical of home appliance applications. By combining expert material selection with controlled heat treatment, our components offer the vibration resistance and tensile strength needed for demanding mechanical environments.

Manufacturing Process for Your Bolts:

We follow a rigorous manufacturing flow designed for world-class reliability and total JIS compliance. The process begins with a detailed review of your technical drawings or international standards, followed by high-speed multi-station cold heading to form the bolt head and body. We utilize precision thread rolling to create accurate threads and apply controlled heat treatment to reach specific strength classes, ensuring the bolt can withstand significant mechanical loads. After durable surface treatments such as Zinc Cr3 plus plating, every batch undergoes salt spray verification and 100% optical sorting under Japanese quality management systems to guarantee that only perfect fasteners reach your production line.
