This Frame Screw M12x1.75×116.50 is a critical, high-strength fastener engineered for demanding structural applications in automotive and truck chassis, suspension, and frame assembly. Its precise specifications are not arbitrary; each dimension defines its role in ensuring vehicle integrity and safety. The "M12" denotes a 12mm metric thread diameter, a size chosen for its optimal balance of strength and material compatibility in heavy-duty components. The "1.75" indicates a fine thread pitch of 1.75 millimeters between threads. This finer pitch offers superior clamping force distribution, enhanced resistance to vibration-induced loosening, and allows for more precise tensioning during installation compared to standard coarse threads.

The "116.50" specifies the overall screw length of 116.5 millimeters. This exact length is crucial, as it must be sufficient to pass through all assembled components—such as frame rails, brackets, or bushing mounts—while providing adequate thread engagement within the receiving nut or tapped hole to achieve its full rated strength. Typically manufactured from high-grade steel, often a class 10.9 or higher, and frequently featuring a corrosion-resistant zinc or phosphate coating, this screw is built to withstand extreme stress, shock loads, and harsh environmental conditions.

When replacing a frame, suspension, or steering component, using an exact specification replacement fastener like the Frame Screw M12x1.75×116.50 is non-negotiable for maintaining original equipment (OE) safety standards. Never substitute with a fastener of incorrect length, thread pitch, or strength rating, as this can compromise the entire assembly’s integrity. Always torque to the vehicle manufacturer’s specified setting using proper tools to ensure secure, reliable performance for the life of the vehicle.
