Socket Head Cap Screw
There are many different types of screws used in manufacturing, construction, solar installation and automotive. Each serves a specific purpose and provides a fast, secure connection to other components. However, there are some types of screws that are more suited to certain applications than others. In this article, we’ll explore the differences between cap screws and socket screws so you can better determine which type is best for your next project.
Socket Head Cap Screw
Socket head cap screws (also known as Allen head or Hex socket cap screws) are a preferred choice for applications where bolts and nuts can’t be used. They have a cylindrical, barrel-shaped head with an inset hexagon drive that can be used with hex keys or wrenches. These screws are typically stronger than other screw types, able to withstand a greater compressive load and resist rotational movement.
They are also more resistant to vibration than other fasteners due to their large, flat head with a hex drive. This larger face distributes the force of the hex drive more evenly than other screw heads, making them ideal for low-clearance applications.
They come in a variety of sizes, styles and finishes. You can find a wide variety of options from Parker Fasteners, who uses DFARS-sourced steel to produce these robust fasteners. Their standard inch series caps have a tensile strength of 180,000 psi, while their metric hex socket head screws are rated for 170,000 psi. Socket Head Cap Screw
