Securing clutch plates (discs) to flywheels is an extremely high-load, high-heat, and high-vibration application. This joint is subjected to massive cyclical torsional forces (from engine pulses and engagement), high axial clamping loads, and intense heat generated during clutch slip and engagement. While the friction material does the primary work, retaining compounds are often used on the bolt threads and/or the register fit to ensure the absolute rigidity of the assembly, preventing micro-shift and bolt loosening, which can lead to clutch chatter and failure. Note: For the retention of components like clutch pressure plates or the primary friction plate assembly to the flywheel (often using bolts and a precision register), a high-strength retaining compound is sometimes used on the register fit to prevent fretting corrosion. Since the primary retention is by bolts, the function of the compound is to eliminate radial play and enhance bolt security. However, since the primary need for this critical bolted assembly is often threadlocking (on the bolt threads themselves, often with high-strength red threadlocker), and for register retention, the highest strength retaining compound is selected.
