Heavy Square Nut

The heavy square nut can be inserted into a square hole or slot to prevent rotation when tightened. It can be used for heavy loads in construction, machinery or agricultural equipment. The extra thickness makes it more durable and suitable for environments where standard nuts can slip or fail.

Product details and parameters

Heavy square nut is usually used in trucks, excavators or heavy machinery, the material is generally selected steel, strong thread, can withstand large pressure. The edge design is square, the nut is not easy to slip when the tool is clamped, suitable for frequent disassembly. For example, installed on the support of the crane, even if the long-term vibration nut is not easy to loose. The surface is usually galvanized or coated with anti-rust layer to prevent rust in the wet environment of the site.

Heavy square nut is often used in mining equipment or building frames, even if there is gravel and sand around, it is not easy to stick the thread. Although the chamfer edge of the nut is not obvious, it can reduce the wear of tools (such as wrenches) and avoid breaking teeth when hard twisting. However, the disadvantage is that the "large", the installation must leave enough space, do not force into the narrow position, otherwise it will be compressed and deformed. After long-term use, the thread may have wear marks, at this time it is recommended to directly replace the heavy square nut.

Maintenance Tips

Heavy square nut is often used in trucks, excavators or construction equipment, and it is easy to wear or loosen under long-term stress. You should check the threads and edges regularly for cracks or chipping. If you find a small problem, do not delay, promptly replace. When cleaning, use a wire brush to scrape off the mud or iron filings on the nut, and do not let the debris get stuck in the thread. If the equipment is in a humid environment (such as a construction site or a dock), the nuts are prone to rust, spray some anti-rust agent and wipe off, and apply a thin layer of oil to prevent moisture.
