Also, referred as custom fasteners the specialty fasteners are commonly found in applications where the standard fastener cannot provide the required structural integrity of performance. They are designed as per specific function and requirement of the project.

They are different from standard fasteners as they are thoughtfully engineered for unique purpose or application. They are used for critical applications where the safety and reliability is the main concern. They have more robust thread pattern that makes them better for heavy duty applications like welding, stamping, assembly and many more manufacturing process.

They come in various shapes, sizes and materials to meet the demand of the project they will be used for. They are also customized by manufacturers as per customer needs and specifications.
Some of the common examples of specialty fasteners

  1. Shear pins: They are used in safety applications where the component must be disengaged during overloads. They are engineered to fail under specific amount of force, at point where it shears at predetermined point.
  2. Twelve-point socket flange screws: These are threaded fasteners with 12 external or internal points with a flange. They are used as a replacement for regular socket head cap screws.
  3. Lock washers: They are used to prevent a fastener from loosening due to vibration. They are used in high pressure and temperature where standard springs are not suitable.
  4. Star-drive screws: They comprise a cross-shaped head with deep wings and are ideal for plastic, wood and sheet metal use. They are used to secure the objects.
  5. Six-point specialty screws: They are designed to fit in a pre-drilled hole and feature six points on head that help minimize the risk of stripping them when tightened. They are compact and light in weight and are perfect for projects where weight and space is limited.
  6. Tribular screws: They are engineered to provide more torque than standards fasteners, making them ideal for materials like plastic and aluminum. These specialty fasteners are resistant to vibration loosening.
  7. Self-threading screws: They are designed to cut their thread into the material they are being screwed into.
  8. Electronic and automotive fasteners: They are designed to securely hold parts together, provide electrical insulation, absorb shock and vibration and protect against environmental elements like dust, dirt, heat and more. Some of the examples are self-threading nuts, bolts, clips, washers and more.

Why use specialty fasteners for project?
