BCT® stands for Bulge Control Technology. The idea behind this is a new construction of rivet nuts that better fit where you need them. BCT® has four cross holes on the shank, so it can control where the bulge starts to form. This allows for the best fitting into irregular holes.

The BCT®* Multigrip is a type of BCT® rivet nut. The Multigrip gives you a grip range that is much better than standard rivet nuts. In fact, the grip range is almost three times of a standard rivet nut. This allows one rivet nut to cover different grip ranges.

The importance of that lies with the cost savings and flexibility. The BCT® Multigrip can be used in applications where you would normally need several rivet nut sizes because of different material thicknesses. With the BCT® Multigrip, you don’t need all those other sizes; you can have a reduced rivet nut inventory which is more cost-effective for you. You can also have more design flexibility with the BCT® Multigrip because you won’t be forced into one thickness.

What is the best kind of application to use BCT® Multigrip? Well, these rivet nuts have controlled deformation of the bulge, so they can be used in many materials. They are ideal for application on thin materials or brittle and soft materials like plastic, rubber and composites.

When choosing a fastener, it is important to look at the material of the fastener as well as what you are trying to fasten. This is important because you have to consider factors like the material strength, brittleness, and corrosion resistance.

Sometimes the strongest products seem small and simple, but they will do the job in the best way possible. The BCT®* rivet nut is a fastener that can be simple, but it does the job it needs to do and it is stronger than the competition. BCT® thrives in tough situations.

BCT stands for Bulge Control Technology and this technology gives you a high performance fastener solution. BCT® has four cross holes on the shank, which determines where the rivet nut will collapse allowing it to be installed in many non-conventional blind applications. The BCT® provides a strong thread compared to other rivet nuts.

BCT® is also easily assembled into hard to access structures. They can be assembled in virtually any material, like ultra-high strength steel, which is what makes them so impressive. They are blind rivet nuts of a high-grade material which makes them able to withstand a lot. If you are unsure of the material thickness or the material thickness varies, that is also a good reason to use the BCT® because it covers a very wide grip range.

With Bossard Proven Productivity, we ensure that your BCT® blind rivet nut will be safe and reliable, just like our other products. We would love to hear from you! Contact us at ProvenProductivity@bossard.com with inquiries and comments about our quality products.

When you are looking for fasteners, you are trying to evaluate the situation and pick the best way to put materials together. Fastening one or more pieces of light, medium, or heavy gauge sheet metal together may require the use of adhesives, riveting, or self-tapping screws. If an application requires access or several layers, tapping screws may be the best option.

First, what is a self-tapping screw? Tapping screws eliminate the need for drilled holes, as they are designed to cut their own hole as it is screwed into the materials. This creates a good snug fit between the mating threads and allows the parts to be reassembled if necessary.

The three basic types of tapping screws are Self-Tapping, Self-Drilling, and Self-Piercing.

Self-Tapping: Cuts its own thread while being driven into the mating material. The thread cutting screw makes a small hole while entering the material which creates a tight friction fit between the threads. This helps fight vibration loosening and allows the parts to be taken apart if needed. Mostly used in 1-2-layer thin gauge sheet metal applications.

Self-Drilling: Like self-tapping, this type of screw has a drill point which allows it to cut through thick and hard material without having to drill a pilot hole.

Self-Piercing: This screw can pierce the material at sharp angles between 25 to 30 degrees at high speeds.

Note: The Self-Tapping family of screws may create chips of metal between the mating parts. This limits their use in electrical, food, and other applications.
