The T301JIS spiral groove metric coarse thread series is a specialized type of threaded fastener designed for applications requiring efficient chip evacuation, reduced friction, and enhanced performance in demanding environments. This thread series is particularly well-suited for use in materials that generate significant amounts of chips or debris during machining or assembly processes, such as metals, plastics, and composites.The defining feature of the T301JIS series is its spiral groove design, which is integrated into the thread profile. This groove runs along the length of the fastener, creating a helical path that facilitates the removal of chips and debris from the threading area. This design not only prevents clogging and binding but also reduces the risk of thread damage, ensuring smoother operation and longer tool life. The spiral groove also helps to lower heat generation by reducing friction between the fastener and the material, which is particularly beneficial in high-speed or high-torque applications.The metric coarse thread designation indicates that the T301JIS series adheres to the ISO metric thread standard, with a larger pitch compared to fine threads. This makes it ideal for applications where rapid assembly or disassembly is required, as the coarse threads allow for quicker engagement and reduced threading time. The metric system ensures compatibility with a wide range of industrial equipment and components, making the T301JIS series a versatile choice for global applications.The T301JIS spiral groove metric coarse thread series is engineered for durability and precision. The threads are typically manufactured from high-strength materials, such as alloy steel or stainless steel, to withstand high loads and resist wear and corrosion. The precise machining of the spiral groove ensures consistent performance and reliability, even in challenging conditions.Applications for the T301JIS series are diverse, ranging from automotive and aerospace industries to construction and manufacturing. It is commonly used in drilling, tapping, and threading operations, where efficient chip evacuation and reduced friction are critical. Additionally, its design makes it suitable for use in blind holes or deep cavities, where debris accumulation can be a significant issue.In summary, the T301JIS spiral groove metric coarse thread series is a highly effective solution for applications requiring robust performance, efficient chip removal, and compatibility with metric standards. Its innovative design, combined with high-quality materials and precision engineering, makes it a reliable choice for professionals seeking optimal results in their threading operations.
