Neoprene washers, on the other hand, add an extra layer of functionality to this equation. Made from synthetic rubber, they provide an excellent seal against water, air, and even chemicals. These washers not only prevent leakage but also act as a buffer, distributing the load exerted by the screw uniformly, thereby preventing damage to the surface beneath. Their flexibility and resilience make them suitable for use in dynamic or vibrating environments, such as automotive, plumbing, and electrical installations.

There are primarily two types of resin anchors polyester and epoxy. Polyester resin anchors are typically used for medium loads and general applications, while epoxy resin anchors are designed for heavy-duty applications requiring enhanced strength and bond performance. The choice between these two types depends on various factors, including load requirements, environmental conditions, and the type of concrete. Additionally, some resin anchors are designed to be used with certain types of rebar or meshwork, providing further versatility for construction professionals.
