Losi LOS3938 Button Head Screws M4x16mm Steel

This Losi button head screw is machined from strong steel alloy and sized M4 x 16mm, providing a precise, factory-correct fit for Losi RC cars and trucks. Its low-profile button head sits close to the mounting surface while still offering a full hex socket for reliable torque transfer, making it well suited to chassis plates, shock towers, and suspension arm attachment points where clearance for moving parts matters. Steel alloy construction gives the screw strong tensile strength and resists stripping, camming out, or shearing under the repeated vibration and impact loads RC vehicles see off-road, so the socket keeps a clean grip on the driver bit through repeated maintenance. This screw serves as a direct factory replacement, matching OEM dimensions and thread pitch so it drops straight into stock mounting points without modification. It also works well for builders replacing worn, rounded, or lost hardware, since consistent quality keeps torque specs accurate across a build. Each package includes 10 screws, enough to refresh several assembly points in one order or keep spares on hand for future repairs.
