These uxcell square nuts are perfect for when you need more bearing surface than regular hex nuts provide. The M4 size with 0.7mm pitch coarse thread works great with square-headed bolts and many machine screws too. Each nut measures 7mm square by 2mm thick, giving you that wider surface area that really helps prevent loosening from vibration. Made from carbon steel with white zinc plating, they're corrosion-resistant and durable for both indoor and outdoor use. The 25-piece pack gives you plenty for current projects and extras for your hardware collection. They're super versatile - use them in furniture assembly, equipment repair, construction projects, electrical work, or industrial machinery. The square design means you can hold them in place with a wrench while tightening the screw, which is way easier than trying to keep a regular nut from spinning. Whether you're building IKEA furniture, fixing appliances, or working on DIY projects, having these square nuts on hand makes assembly so much smoother. They're one of those basic hardware items that every toolbox should have!
