Product Description

Oil drain bolt plays a vital role in mechanical equipment, its role is mainly reflected in the following aspects:

Enhanced sealing: as the oil has strong permeability, oil drain bolt can effectively prevent oil leakage, to ensure that the oil will not be lost without reason.
Auxiliary oil preheating: oil drain bolt also helps to preheat oil, this function can significantly reduce engine wear in cold start, extend engine life.
Adsorption of metal impurities: The strong magnetic drain bolts can absorb metal powder in the oil and large iron scraps caused by abnormal wear, prevent these metal impurities from being sucked into the oil pump, thereby avoiding damage to other parts of the engine.
