Nuts are used alongside bolts to secure components together. The nut’s internal threads allow it to fit onto the bolt’s shaft, creating a tight connection when tightened. There are several types of nuts, including hex nuts, lock nuts, and wing nuts. Lock nuts are designed to resist loosening under vibration, making them well-suited for applications in dynamic environments. Wing nuts, with their unique design, can be easily tightened or loosened by hand, making them useful in situations where frequent adjustments are necessary.

2. Pilot Considerations Although these screws do not require pre-drilling, it can be beneficial in harder materials to create a pilot hole to guide the screw and reduce pressure.

When using self-drilling screws galvanized, it's important to follow the manufacturer's guidelines for installation to ensure the best results. This includes using the correct size drill bit and setting the drill to the appropriate speed and torque for the type of material you are working with. Proper installation will help ensure that the screws hold securely and provide long-lasting performance.

Rivets are permanent fasteners that join materials by means of a mechanical interlock. They consist of a cylindrical shaft with a head at one end and are installed by deforming the unheaded end after insertion. Rivets are commonly used in structural applications such as bridges and aircraft, where a high level of strength is critical. There are different types of rivets, including solid rivets, blind rivets, and tubular rivets. Blind rivets, also known as pop rivets, can be installed from one side of the workpiece, making them ideal for applications where access to both sides is limited.
