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.

Concrete form wedge bolts are specialized bolts designed for use in concrete formwork systems. They typically feature a tapered design that allows for easy insertion and a secure grip once fitted. The wedge shape creates a locking mechanism that holds the formwork in place, preventing it from moving during the pouring process. These bolts are often made from high-strength steel to withstand the pressures and forces exerted by wet concrete, making them reliable for various construction applications.
