Carriage bolts, commonly known as round-head square-neck bolts, are fasteners with a round or semi-circular head and a square neck. They are used with a nut to connect parts with through holes.
Carriage bolts are classified by head size into large semi-circular head carriage bolts and small semi-circular head carriage bolts, and are widely used in electronics manufacturing, machinery equipment, chemical industry, automotive industry, and many other fields.
Hexagon Bolts are threaded bolts characterized by their hexagonal heads. Hexagon bolts come in fully threaded and partially threaded versions and are widely used in applications such as machinery and construction.

High Strength Hexagon Bolts refer to bolts with a strength grade of 8.8 or higher, commonly using strength grades 8.8s and 10.9s, with 10.9s being the most prevalent. High Strength Hexagon Bolts require a large preload and are frequently used for connections in structures such as bridges, rails, and high-voltage and ultra-high-voltage equipment.
U bolts, also known as saddle bolts, are non-standard parts named for their U-shaped shape. They are threaded at both ends for use with nuts and are primarily used to secure tubular or sheet-like objects. Because the way they secure objects resembles a person riding a horse, they are called saddle bolts.
