{"product_id":"losi-los3927-button-head-screws-m4x40mm","title":"Losi LOS3927 Button Head Screws M4x40mm","description":"\u003cp\u003eThis Losi button head screw is machined from strong steel alloy for reliable strength under the repeated vibration and torque loads found throughout RC chassis and driveline assembly points. Sized M4 x 40mm, it functions as a direct factory replacement for original Losi hardware, restoring correct fit and clamping force anywhere the OEM specification calls for this length and thread pitch. The button head profile offers a low, rounded shape that keeps clearance in tight areas while its hex socket drive allows solid torque application during installation without rounding out, a common issue with lower-quality fasteners. Because Losi vehicles rely on hardware kits engineered to exact tolerances, replacing worn, stripped, or lost screws with the correct factory-spec part helps preserve proper alignment and structural integrity in the chassis, suspension, or drivetrain assembly it came from. This is general-purpose Losi RC hardware rather than a part tied to one specific vehicle platform, which makes it a practical item to stock for ongoing maintenance, crash repair, or hop-up builds across the Losi vehicle lineup. The extra length makes it well suited to thicker mounting stacks. The package includes 10 screws, enough for a full hardware refresh or several individual repairs.\u003c\/p\u003e","brand":"Losi","offers":[{"title":"Default Title","offer_id":55906286403906,"sku":"LOS3927","price":10.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5063\/8402\/files\/LOS-3927_A0_I6BXIDZV.jpg?v=1786573533","url":"https:\/\/www.powerhobby.com\/products\/losi-los3927-button-head-screws-m4x40mm","provider":"PowerHobby","version":"1.0","type":"link"}
