Bolts are one of the most crucial mechanical fasteners in the industrial world. Engineered for joining materials with precision and strength, bolts are designed to handle everything from high-pressure environments to everyday mechanical assemblies. Available in various sizes, shapes, and materials, bolts provide a secure and removable connection that makes them a preferred choice across multiple sectors—construction, automotive, oil & gas, marine, and manufacturing.

A bolt is a type of threaded fastener that requires a nut for proper installation. It typically features a head on one end and threads on the other, enabling torque to be applied for tightening. Unlike screws, which are generally used without a nut, bolts offer greater clamping force and reliability. They are manufactured in a wide range of specifications to meet diverse operational demands and are frequently paired with washers to ensure load distribution.
One major advantage of bolts is their reusability. Components can be disassembled and reassembled multiple times without compromising the integrity of the bolt. They also offer superior load-bearing capacity and precision in alignment, especially when compared to welding or riveted joints. Their ability to maintain joint strength under dynamic loads makes bolts an ideal choice for heavy-duty and high-performance applications.
