5. Improved Alignment Accurate alignment of formwork is critical for achieving the desired dimensions and flat surfaces in concrete structures. Wedge bolts help to maintain this alignment, providing a straight and stable framework for the concrete. This is essential for ensuring the quality and aesthetics of the finished concrete surfaces.

1. Improved Sealing The primary advantage of using rubber washers is their ability to create a watertight seal. This is invaluable in plumbing, roofing, and any situation where fluid containment is critical. By preventing leaks, these fasteners help protect materials and structures from water damage and corrosion.
