Tower Bolt Stainless Steel

The head is hexagonal, just like the bolt head. It can be tightened with an open-end wrench, a ring wrench, or a socket. The size of the opposite side of the hexagonal head should be made according to the standard, and the wrench should not loosen or shake when clamped. The plug is generally tightened, and the hexagonal head can withstand greater torque than the inner hexagonal head, making it less prone to twisting.

The light plug does not have a seal and relies on the thread itself for sealing. It is generally used in conjunction with raw material tape or thread sealant, and is suitable for low-pressure water and gas. The ED ring with a sealing ring has an O-ring or combination gasket at the root of the plug. After tightening, the gasket is tightly pressed onto the end face, ensuring reliable sealing and suitable for hydraulic systems. Pre coated with sealant, the threads have already been coated with anti loosening sealant, which can be screwed in and used, saving one coating process. We can provide all three options, and customers can choose according to their usage pressure.
