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.
