What Are Specialty Fasteners?

Fasteners play an integral part in many different industries. They are used to hold two objects together.

The most common types of fasteners are nuts, screws, and bolts. But there are also specialty fasteners used for a specific purpose or application.

Specialty fasteners, sometimes referred to as custom fasteners, are commonly found in applications where the standard fastener cannot provide the required structural integrity or performance. They are designed according to a specific function. That’s why learning about specialty fasteners can help you choose the right one for your next project.

Many manufacturers produce proprietary specialty fasteners that can’t be easily duplicated. This helps the designer protect their IP and bring profits to the company when a user needs to buy a replacement specialty fastener.

What Are Specialty Fasteners?

Specialty fasteners are fastening systems that are different from your typical fasteners because they are designed for a unique purpose or application. They are often used for critical applications where safety and reliability is the primary concern. 

Specialty fasteners have a more robust thread pattern, which makes them better for heavier-duty applications, such as welding, molding, stamping, assembly, and many more manufacturing processes.

Custom fasteners come in various shapes, sizes, and materials to meet the demands of the application it will be used for. Manufacturers can also customize them according to customer requirements and specifications.

Common Examples of Specialty Fasteners

These specialty fastening systems come in different types and are manufactured for specific engineering designs and demands. Furthermore, these types of components are always in demand and are used to secure specific products that attach metals, plastics, or composite materials. Some of the most common examples of specialty fasteners include:

Shear pins

Shear pins are designed to fail under a specific amount of force, which is when it shears at a predetermined point. They are used primarily in safety applications where a component must be disengaged during overloads.

Twelve-point socket flange screws

These are threaded fasteners with 12 external or internal points with a flange that looks like a washer. Their features make them suitable as replacements for regular socket head cap screws.

Lock washers

Lock washers are used to prevent a fastener from loosening due to vibration. These are commonly used in high-temperature and high-pressure applications where standard springs are unsuitable.

Star drive screws

This fastener comprises a cross-shaped head with deep wings and is ideal for plastic, wood, or sheet metal use. They can secure objects together without the need for nuts or bolts. 

6-point specialty screws 

These screws are designed to fit snugly in a pre-drilled hole and feature six points on the head that help reduce the risk of stripping them when tightened. They are perfect for projects where space or weight is limited, as they’re compact and lightweight. 

Trilobular screws

Trilobular screws are a type of specialty fastener that are designed to provide more torque than regular fasteners, making them ideal for materials like plastic and aluminum. These specialty fasteners are also resistant to vibrational loosening. 

Self-threading screws

Self-threading screws are designed to cut their thread into the material they’re being screwed into. This makes them a convenient option when you don’t have access to a tap or die set and need to create a threaded hole in a material that would otherwise be difficult to thread. 

Electronic and automotive fasteners

Common examples of electronic and automotive fasteners include self-threading screws, nuts, bolts, rivets, clips, posts, and washers. These fasteners are designed to securely hold parts together, absorb shock and vibration, provide electrical insulation, protect against environmental elements such as moisture, dust, dirt, and heat, and create a tight seal for airtight applications.

Nuts are one of the most common fasteners and come in various shapes and sizes. They can be made from different materials, such as brass, stainless steel, aluminum, or plastic. Most nuts have an internal thread that screws onto mating parts that have an external thread. 

Materials for Specialty Fasteners

Specialty fasteners are made out of a variety of materials. They have qualities that make them ideal for a particular application or purpose. These materials include:

  • Stainless steel
  • Aluminum
  • Copper
  • Monel
  • Inconel
  • Carbon steel
  • Brass
  • Bronze
  • Nickel alloy
  • Titanium
  • Exotic Metals

For instance, stainless steel fasteners are ideal for applications where the material is exposed to outside elements as it’s highly resistant to corrosion. On the other hand, titanium is a popular choice for projects where the strength-to-weight ratio is a huge consideration.

Why Use Specialty Fasteners for Your Project?

Using specialty fasteners offers many advantages that can help you save time and money on your next project. Here are some benefits to consider:

  • No need to use additional fastening tools: Specialty fasteners prevent you from using different standard fasteners that can affect the integrity of your project.
  • Customizable: Specialty fasteners can be customized according to your exact specifications, which allows you to get a unique fit for your project. It helps ensure that all parts fit securely into place.
