Expansion Bolt

Expansion bolts consist of the countersunk head bolt, expand sleeve, flat washer, spring washer and hex nut. When in use, as the nut is tightened, the bolt, expansion sleeve, piece to be installed and fixed piece are all expanded into a single unit. This makes them especially useful for securing the pipeline to supports such as hanger brackets, brackets or other equipment on walls or pillars.

As a professional fastener manufacturer, CH has more than 10 years of experience in offering customers expansion bolts in different materials and sizes.
