Losi LOSA6221 4-40 x 5/8" Cap Screws 8ight E 4wd

The Losi LOSA6221 is a pack of cap head screws sized 4-40 x 5/8 inch, built for the 8IGHT E 4wd. Cap head screws use a taller, cylindrical head profile that gives you more surface area for a hex driver, which helps when a mounting point needs to be torqued down securely without the risk of rounding off the head.

This size is used at specific chassis and suspension mounting points on the 8IGHT E 4wd where that added grip matters most. As with any small hardware, these screws are prone to going missing during a teardown or getting stripped from repeated use with a worn-out hex key, so having a dedicated pack of the correct size on hand saves you from substituting the wrong screw mid-rebuild. This genuine Losi pack matches the factory 4-40 x 5/8 inch specification exactly. Stock up to keep your 8IGHT E 4wd's hardware fresh and reliable.
