Installation involves several steps. First, holes are drilled into the foundation to the exact depth and diameter required for each bolt. The bolts are then inserted, often with a nut and washer attached at the end to maintain position. A chemical grout or concrete is then poured around the bolt to fill the void, creating a strong mechanical connection. Once the concrete has cured, the nuts are tightened, securing the structure to the foundation Once the concrete has cured, the nuts are tightened, securing the structure to the foundation Once the concrete has cured, the nuts are tightened, securing the structure to the foundation Once the concrete has cured, the nuts are tightened, securing the structure to the foundationfoundation bolt fixing.

The rubber washer plays a crucial role in this assembly. Made from durable and resilient materials, such as neoprene or silicone, it offers excellent compression and sealing properties. When tightened, the rubber washer compresses between the screw head and the surface it's fixed to, creating a waterproof and airtight seal. This is particularly beneficial in situations where leakage or environmental elements need to be kept at bay, such as in roofing, plumbing, or automotive applications.
