About Fasteners

Industrial fasteners are fundamental components in manufacturing and construction, holding together two or more parts. These essential elements, which include screws, bolts, nuts, and rivets, are used to join together materials in a non-permanent fashion, allowing disassembly when necessary. They span a spectrum of sizes, designs, and materials, catering to various applications, from skyscraper construction to intricate electronic devices.


Hex head cap screws are a specific type of fastener characterized by their hexagonal head and machine thread. They are primarily inserted into pre-drilled holes or with a matching nut. The hexagonal shape of the screw head means greater torque can be applied during installation and removal, making these screws ideal for use in heavy-duty applications. Their cap typically covers the threaded portion of the screw, providing a smooth finish and preventing potential injury or snagging that could occur with exposed threads. Hex head cap screws are commonly used in automotive, construction, and various mechanical applications.


Socket screws, sometimes referred to as Allen screws, are a type of fastener used in many applications due to their unique design. Their distinguishing feature is an internal hex drive, which allows for tightening or loosening with an Allen wrench. This characteristic brings several advantages, including a smooth outer surface, which is aesthetically pleasing and less likely to cause injury or snag on materials, and the capacity to withstand high torque. Socket screws are especially useful in assemblies requiring a strong bond or in areas with limited space for a traditional wrench or screwdriver.


Set screws function by securing one object inside another, preventing any relative motion between the two. They work well with shaft collars, pulleys, gear hubs, or similar applications. The screw is inserted into a threaded hole in the outer object and tightened until its end point applies sufficient pressure against the inner object. This force creates enough friction to prevent the internal object, often a rotating shaft, from moving, thus ensuring alignment and precision in various mechanical systems.


A shoulder bolt, sometimes called a stripper bolt, is a machine screw with a unique design. The bolt features a head, a shoulder, and a threaded section. The shoulder is larger in diameter and smoother than the threaded section. When inserted into a hole, the shoulder allows for a rotating or sliding movement of the attached parts while the threaded section secures everything. The head, typically hexagonal or socket-shaped, enables tools for tightening. Shoulder bolts are commonly used in applications that require precise pivoting or movement, such as in machinery linkages and guides.
