What Is a Taptite Screw?
A Taptite screw is a high-performance screw that does not require a female thread. A similar screw is called a tapping screw, but its shape and characteristics are different. A normal screw consists of a bolt, called a male thread, and a nut, called a female thread. Both of these threads are combined to fasten the screw. However, a Taptite screw does not require a female thread. Because of its shape, it can be fastened directly to the mating side by applying a female thread when tightening.
Uses of Taptite Screws
Taptite screws are used in various places because of their high performance. For example, they are used in situations where high workability is required. Since a female screw is not required, the Taptite screw can be used alone for fastening, thereby increasing work efficiency. Also, since the torque is relatively small, the burden of fastening is low. They are used for plastics and thin plates. On the other hand, they are not suitable for cases where removal is required. This is because it is highly effective in preventing loosening, and once fastened, it is difficult to remove the fastener.
Principle of Taptite Screws
Taptite screws have excellent features due to their unique shape.
Like the tapping screw, the Taptite screw has a simple structure, but the shaft part is characterized by a triangle in the shape of a ball. The apex of the triangle pushes the mating side apart to form a female thread. This structure of has several excellent features.
- High Work Efficiency
Features of this screw are its high work efficiency compared to other screws. Since only the apex of the triangle touches the side of the hole, less torque is required. This allows for tightening with little force, thus increasing work efficiency. However, if the bottom hole is too small, the torque will also be too large, so care must be taken. It is necessary to drill an appropriate pre-hole to the extent that the Taptite screws do not loosen. - Difficult to Loosen
Another feature of a Taptite screw is that it is difficult to loosen. When a female thread is processed by pushing and expanding the mating side, the material expands and contracts, generating a resistance force. This force reduces the loosening of the Taptite screws and provides a high loosening resistance effect. It can also be used for products subject to vibration or impact.
