Our expertise includes manufacturing and supplying custom bolts tailored to meet the unique needs of our customers. As one of Qatar’s top producers of large-diameter bolts and nuts, we specialize in high tensile and stainless steel grades, as well as fasteners used in major projects within the power, renewable energy, wind, and infrastructure sectors throughout Qatar.
A bolt is a fastener with a spiral thread on the outside, designed to be tightened or loosened by twisting. It pairs with a matching nut that has a thread on the inside. Bolts are commonly used to form a strong connection by combining the nut’s clamping force with the bolt’s ability to hold parts securely, preventing sideways movement. Many bolts have a smooth section, called the grip length, which acts like a pin, making the joint even stronger. While this smooth part is often thought to distinguish bolts from screws, it’s more about how they are used rather than a strict difference between the two.
