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.

Self-drilling screws, as the name implies, eliminate the need for a separate drilling step, as they have a cutting tip designed to pierce through material without requiring a pilot hole. This not only saves time but also reduces the risk of material damage that can occur with traditional drilling methods. The 1 1 4 self-drilling screws refer to a specific size, which typically signifies a 1/4-inch diameter and a 4-thread pitch. The numbers '1' and '20' often represent the diameter in imperial measurements, while '4' indicates the number of threads per inch.
