It is crucial to couple these nuts with the correct-sized screws, since any mismatch could lead to structural failure. To install the nut, first drill a hole larger than the barrel of the nut. Then, push the projections against the substance to maintain their position. Now, an externally threaded bolt may be used to secure the nut. It is composed of stainless steel, carbon steel, and alloy steel to withstand more abrasion and corrosion.
