As anchor bolt cap, this bolt cap separates a cap to protect an anchor bolt and a nut into an upper cap and a lower cap so that both the caps can be fully sealed to perfectly cover up the inside of the caps and protect an anchor bolt and a nut from corrosion. The cylindrical lower cap and upper cap facing the hexagonal side of a nut hold a thread to be fastened with an anchor bolt, which pressurizes the lower cap onto the floor by fastening with the anchor bolt on the top.
The rubber sealing positioned between the upper cap and the lower cap is installed at the bottom of the lower cap to cover up the lower cap and floor. As anchor bolt cap including sealing means to fully seal the inside of the cap body, a square groove is formed on the top of the upper cap to facilitate maintenance at any time and see whether or not a bolt or a nut is loosened.
The upper stopper may be separated and when it is opened, a square groove appears as shown in the figure to facilitate maintenance at any time.
For the upper/lower rubber sealing, pressurizing the upper cap also pressurizes the upper rubber sealing and lower one to fully keep the inside airtight.
The bolt fastening rubber pressurizes the upper cap and minimizes a space between nut and upper cap as well as vibration to prevent the nut from loosening.
