Losi LOS3944 Button Head Screws M4x35mm Steel

This Losi button head screw is machined from strong steel alloy and sized M4 x 35mm, an extended length built to a precise, factory-correct fit for Losi RC cars and trucks. The low-profile button head sits close to the mounting surface while still offering a full hex socket for reliable torque transfer, and the longer shaft suits thicker assemblies such as shock towers, chassis braces, or stacked mounting points that need more thread engagement. Steel alloy construction gives the screw strong tensile strength and resists stripping, camming out, or shearing under the 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 is 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. Each package includes 10 screws, enough for multiple repairs or a full parts-bin restock.
