| High Light | Heavy Duty Hex Bolt Set HDG ，Complete Bolt Nut Washer Kit ，Carbon Steel Heavy Fastening Set | ||
This is a set of heavy-duty fasteners designed for reliable and durable connections in industrial, building, and outdoor environments. It includes a hexagonal bolt, matching nut, flat washer, and spring washer, all of which have been treated with one of three anti-corrosion coatings. HDG (hot-dip galvanizing) provides thick zinc protection for outdoor or mildly humid environments such as steel frames. Geomet provides durable and environmentally friendly coverage, making it an ideal choice for indoor industrial machinery. Dakro has excellent chemical resistance and weather resistance, making it suitable for chemical plants or coastal structures. Flat washers distribute pressure to prevent surface damage, while spring washers prevent loosening due to vibration. This kit is suitable for tasks that require strong clamping force and anti-corrosion performance, such as structural steel fastening, heavy machinery assembly, and outdoor equipment installation.
