Bolt types

• Hex head bolts

A hex head bolt is a bolt with a regular hexagonal head. It requires a wrench (such as an open-end wrench, socket wrench, or socket set wrench) to tighten or loosen. It is typically used with a nut or screwed into threaded parts to connect and secure two or more parts with through holes. It is one of the most widely used and common types of bolts.

• Hex socket head cap screws

The standard name for hex socket head cap screws is "cylindrical head socket head cap screw". They are characterized by a cylindrical head with a hexagonal recess (internal hexagonal hole) at the top. An L-shaped hex wrench is needed to tighten them. They are the preferred choice for threaded connections or installations requiring a tight and aesthetically pleasing finish.

• Diagonal head bolts

"Diagonal head bolts" typically refer to bolts with a flat bottom surface, a flat or slightly curved top, and a cylindrical side surface. Their design aims to ensure that, after installation, the head is flush with or slightly recessed into the surface of the part, preventing bulging and ensuring a smooth finish.

• Fully threaded studs

are fasteners with external threads machined along their entire length. They lack a traditional "head," and both ends are usually flat, though one or both ends may have chamfers to facilitate screwing in.

Main production standards: ASME, DIN, GB, etc.
