Sur Inc. are manufacturers and exporters of Spring Channel Nuts in India. Spring channel nuts, also known as spring nuts or strut channel nuts, are specialized fastening components designed for use in metal framing systems like strut channels, providing a secure threaded connection point for bolts and fittings. These nuts feature a rectangular shape with a threaded hole and serrated grooves that grip the channel edges, ensuring firm locking and preventing loosening due to vibration.

Spring channel nuts are available in different types such as long spring, short spring, and top spring variations to suit various channel depths and applications, while materials like zinc-plated steel, stainless steel, and hot-dip galvanized finishes provide corrosion resistance and durability.

Spring channel nuts are available in a wide range of thread sizes such as M6, M8, M10, M12, and M14, making them suitable for different strut channel systems and load requirements, while standard dimensions typically include widths of 10–40 mm, lengths of 15–50 mm, and heights of 10–30 mm depending on the design and application.
