Losi LOS3940 Button Head Screws M4x10mm Steel

This Losi button head screw is machined from strong steel alloy and sized M4 x 10mm, giving it a precise, factory-correct fit on Losi RC cars and trucks. The low-profile button head sits close to the mounting surface, offering good clearance in tight spots around chassis plates, shock towers, and suspension arms where a taller head could interfere with moving parts. Steel alloy construction provides strong tensile strength and resists stripping, camming out, or shearing under the vibration and impact loads RC vehicles encounter on rough terrain, keeping 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 installs straight into stock mounting points without modification. It's also useful for builders refreshing worn, rounded, or lost hardware, since consistent quality across every piece keeps torque specs accurate and assembly reliable. Each package includes 10 screws, enough to service multiple assembly points in one order or keep spares on hand for ongoing repairs and maintenance work.
