About this item

  • Complete size combinations to meet various needs: This kit includes three commonly used sizes (3/8 inch, 3/4 inch, 1 inch) of # 10 screws, totaling 180 components. Each size of screw, nut, lock washer, and flat washer is matched equally, making it convenient for you to handle various DIY repair and assembly projects without the need to purchase large quantities of packaging for a single size
  • Made of 304 stainless steel material for sturdy and durable quality: All screws, nuts, and washers are made of high-quality 304 stainless steel, which has excellent rust and corrosion resistance, and can easily cope with humid environments (such as bathrooms, kitchens) and outdoor use. Its high strength and durability ensure the firmness and long-term reliability of the connection
  • Locking and anti loosening design ensures safe and stable connection: The locking washer (spring washer) included in the kit can effectively prevent nuts and screws from becoming loose under equipment vibration or dynamic loads, providing you with additional safety protection. Used in conjunction with flat washers, it can disperse pressure and protect the surface of the fixed object
  • Round head cross design for easy installation and disassembly: The screw adopts a round head design and a Phillips groove, which not only provides a neat and beautiful appearance, but also allows you to use a common Phillips screwdriver for quick and effortless tightening and dismantling operations, greatly improving work efficiency
  • Classified storage and packaging for easy organization: All 180 components are packaged in transparent compartments by type and size, allowing you to easily find the parts you need at a glance. This is convenient for daily use and retrieval, and more conducive to storage and management, keeping the workbench clean and orderly
