Hex Head bolt: Stainless Steel, A2, NL-19, M8-1.25, Coarse, 20 mm lg, Globally Sourced

The head of a hex bolt has a hexagonal shape, allowing it to be gripped and turned by a wrench or socket.

This design provides good torque transfer, making it easy to tighten or loosen the bolt.

The shaft of a hex bolt has external threads along its entire length.

These threads allow the bolt to be screwed into a pre-tapped hole or secured with a nut.

Hex bolts are typically made from steel, stainless steel, or other corrosion-resistant metals.

They are available in a range of strength grades, from low-strength "common" bolts to high-strength "structural" bolts.

Hex bolts are widely used in construction, machinery, automotive, and a variety of other industries.

They are commonly used to secure two or more components together, such as plates, beams, or flanges.

The hexagonal head allows for easy installation and removal using standard wrenches or sockets.

Hex bolts come in different lengths, diameters, and thread pitches to suit various applications.

They may also have additional features like washers, lock washers, or specialty coatings.
