An Allen wrench is also included. This screw assortment is designed to meet daily maintenance, repair, and assembly needs across a wide range of metric fastening tasks
  • 【12.9 Grade Alloy Steel & Black Zinc Plating】The M4 screws assortment kit is made from 12.9 grade alloy steel, which provides high tensile strength, hardness, and wear resistance. The black zinc plated finish of the M4 socket head cap screws , hex bolts and other assorted accessories feature resists rust and corrosion. These fasteners may be used in indoor and light outdoor environments.
  • 【Hex Socket Head, Allen Drive & Spring Washer Design】The recessed hex socket (Allen) drive allows for secure torque transmission and tightening even in confined or recessed spaces. Each M4 socket head screw features clean, burr‑free metric threads (M4 x 0.7) that help ensure smooth engagement with nuts and tapped holes, helping minimize cross‑threading. The M4 spring (lock) washers are designed to provide axial tension when compressed, which helps resist loosening caused by vibration – complementing the flat washers for more secure assemblies.
  • 【Wide Applications】This M4 hardware kit is suitable for a broad range of applications, including 3D printers, CNC machinery, electronics enclosures, RC models and drones, furniture assembly (chairs, small hardware), bicycle repairs, and general DIY projects. Having a complete assortment of metric M4 screws, washers, bolts, and nuts on hand simplifies repairs.
  • 【Organized Storage Box】The M4 bolt kit comes in a sturdy, compartmentalized plastic storage case with dedicated sections for each M4 hex screw size, as well as separate compartments for nuts, flat washers, and spring washers. All pieces remain neatly sorted, clearly separated, and easily accessible, reducing time spent searching for the right fastener. The compact and portable design of the M4 assortment fits easily into tool bags, drawers, or shelves.

Do I need to register my drone with the FAA?

Registration requirements depend on the drone’s weight, equipment, and intended use. Certain drones operated in the United States must be registered and may need to comply with Remote ID requirements. Review current information at the official FAA website before flying.
