Custom Hexagon Socket Head Screw Class 8.8 Blackened High Strength M6M8M12M14M16M20 Socket Screw
An internal hexagon bolt, commonly known as an Allen bolt or Allen screw, is a type of fastener that features a hexagonal socket (also known as an Allen key or hex key) on the head. It is designed to be tightened or loosened using a corresponding hexagonal wrench or key.
Here are some key features and characteristics of internal hexagon bolts:
Head: The head of an internal hexagon bolt is typically cylindrical or slightly rounded, with a recessed hexagonal socket. The socket is used to accommodate the hex key or wrench, providing a secure grip for tightening or loosening the bolt.
Hexagonal Socket: The hexagonal socket on the bolt's head allows for a greater torque application compared to other types of fasteners. It provides a more secure and efficient means of fastening, especially in applications where space is limited.
Threaded Shank: The shank of an internal hexagon bolt is threaded to allow for engagement with a corresponding threaded hole or nut. The threads can be coarse or fine, depending on the specific application requirements.
Materials and Sizes: Internal hexagon bolts are available in various materials, such as steel, stainless steel, or brass, to suit different environmental conditions and application needs. They come in different sizes and lengths, with standard metric and imperial measurements.
