What could happen if aluminum bolts are not lubricated properly?

Proper lubrication of aluminum bolts is crucial for achieving the required torque during installation. When bolts are not lubricated adequately, the friction between the bolt threads and the mating surface increases. This increased friction can prevent the bolts from being tightened to their specified torque levels, which could lead to a weak joint that may not hold under operational stresses.

Additionally, inadequate lubrication can cause the bolt to seize, making it difficult to achieve the desired tightness. This situation not only impacts the performance of the joint but may also interfere with the function of the assembly in which the aluminum bolts are installed. Proper lubrication helps to ensure that the forces are distributed evenly and that the mechanical properties of the bolts are utilized effectively.
