The process for manufacturing internal hexagon screws typically involves the following steps:

1. Wire drawing: The raw material (usually steel wire) is drawn through a series of dies to produce a wire with the desired diameter and surface finish.

2. Heading: The wire is cut into blanks of the appropriate length and heated to a suitable temperature. The heated blanks are then placed into a heading machine, which forms the head of the screw by applying pressure and shaping the metal.

3. Thread rolling: The threaded portion of the screw is created by a process called thread rolling. The screw blank is inserted into a machine that uses a set of dies to deform the metal into the desired thread pattern.

4. Heat treatment: The screw is heated to a high temperature and then cooled rapidly to improve its strength and durability. This process, known as quenching, is followed by tempering to reduce brittleness and improve toughness.

5. Surface treatment: The screw may undergo various surface treatments to improve its corrosion resistance, appearance, or other properties. For example, it may be plated with zinc or another metal, coated with a protective layer, or polished to a high shine.
