Built for Real Farm Work
Ford New Holland 40 Series tractors including models 5640, 6640, 7740, 7840, 8240, and 8340 spend long hours in all kinds of conditions. Whether you’re running a compact 5640 for utility work or pushing a big 8340 through heavy tillage, that rear window takes a beating from vibration, temperature changes, and the occasional tree branch. These screws are engineered to handle the stress and keep your window secure season after season.
Made to Last
This isn’t just any hardware store screw – it’s manufactured to the exact specifications needed for cab window mounting. The threads are cut precisely to match the window frame, and the head design distributes clamping force evenly to prevent glass stress. The finish resists corrosion from moisture and chemicals you encounter around the farm.
Installation Notes
Installing window hardware takes patience but isn’t complicated. Start by cleaning out the window channel completely – old gasket pieces and dirt need to go. Work the new gasket into the channel bit by bit, making sure it’s seated properly all the way around. Don’t over-tighten these screws – snug is good enough. Overtightening can crack the glass or distort the frame, creating more problems than you started with.
