M12 x 50mm Window Back Frame Screw for Tractor Cab Windows SKU: QT409693

When your tractor cab window rattles or won't stay properly secured, a missing or worn back frame screw is often the culprit. This M12 x 50mm replacement screw restores the solid mounting connection your window hardware needs to keep glass panels secure during rough field conditions and transport.

Why This Fastener Matters

• Precise M12 thread pitch and 50mm length ensures proper fit without guesswork
• Eliminates window rattling that leads to frame damage and operator fatigue
• Prevents glass movement that can stress seals and cause costly leaks
• Simple replacement restores factory-spec stability to window assemblies

Don't let a simple fastener compromise your cab's comfort and protection. Start threads by hand to prevent cross-threading and tighten evenly for best results. S&H Parts has the right hardware to keep your equipment running since 1969.
