The terms 3% and 4% often relate to the percentage of the anchor bolt’s yield strength in relation to the concrete’s compressive strength. For example, a 3% concrete anchor bolt means that the bolt can withstand loads up to 3% of the concrete's yield strength, while a 4% bolt can handle loads up to 4%. This distinction is vital for engineers and contractors, as it influences load calculations, safety factors, and the overall design of the structure.

In addition to their sealing capabilities, neoprene washers also provide vibration and shock absorption. When used in conjunction with self-tapping screws, they help to mitigate the impact of vibrations that can loosen fasteners over time. This is particularly crucial in automotive and machinery applications where constant movement and vibration are present. The resilient nature of neoprene ensures that the screws remain securely fastened, reducing the risk of mechanical failure.
