ribbed stainless steel screws with wafer head

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.

The terms 3% and 4% often relate to the percentage of the anchor bolt’s yield strength in relation to the concrete’s compressive strength. For example, a 3% concrete anchor bolt means that the bolt can withstand loads up to 3% of the concrete's yield strength, while a 4% bolt can handle loads up to 4%. This distinction is vital for engineers and contractors, as it influences load calculations, safety factors, and the overall design of the structure.

A full thread stud bolt is essentially a long, cylindrical rod with threads on both ends, designed to be screwed into tapped holes or nuts. The 'full thread' terminology refers to the fact that the entire shaft of the bolt is covered in threads, leaving no unthreaded portion in the middle. This feature makes them highly versatile and adaptable to a wide range of industrial uses where high tensile strength and secure fastening are critical.
