self drilling screws for steel

Expanding plastic screw anchors, often referred to as wall anchors, are designed to secure objects by expanding as a screw is driven into them. Typically made from durable plastic, these anchors are inserted into a pre-drilled hole in the wall. When a screw is inserted into the anchor, it pulls the anchor wings outward, gripping the surrounding material tightly. This expansion creates a hold strong enough to support various weights, making them ideal for a wide range of applications.

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.
