Quality-Assured Hexagon Socket Head Cap Screws

Drill holes according to the diameter of the inner hexagon to meet the requirements.

Use a cold heading machine to upset the hexagonal socket screws. A single piece can be punched with a hexagonal punch and hammered out. Similar to countersunk screws, the head of the screw is embedded in the machine and has a high connection strength, but the screw must be installed and removed using a corresponding hexagonal wrench. Generally used on various machine tools and their accessories.
