Triangular self-tapping screws: the first choice for fastening metal parts
The unique triangular cross-section of the triangular self-tapping screws provides an embedded self-tapping and self-locking device. The locking effect can be improved without any spring pad, so the connection is more reliable, and the expensive tapping device and operation are saved, which reduces the direct cost.
Triangular contour for easy thread forming
1, to ensure complete connection; 2, to overcome the increase in friction; 3, reduce the driving torque.
Complete thread projection surface
1. Improve product consistency; 2. Improve connection efficiency.
Reduce connection costs
The key to reducing connection costs is to remove inefficient processes and unnecessary parts. When the triangular self-tapping screws are locked into the object, the appropriate thread is automatically formed, and the expensive automatic tapping equipment and the tapping process are no longer needed.
Eliminate expensive and time-consuming bottom hole tapping processes and facilities
Improve assembly operations
When installing ordinary self-tapping screws, we often need high torque values ​​to overcome the frictional force. The unique cross-sectional shape of the triangular self-tapping screws is used to reduce the friction. A relatively small torque is enough to mount the screw in place. As the triangular screw rotates, a strong, rigid matrix thread is also formed.
Relieve thread wear and chip problems
Reduce interference between threads
Provides uninterrupted plastic flow for improved connection integrity
Alternative
The standard thread series can be used instead of a machine screw.
Designed to allow the removal and replacement of fasteners
Loose connections when blocking vibration
The mechanical and self-locking characteristics of the triangular self-tapping screws greatly improve the loosening ability under vibration. A unique triangular profile allows the material to flow into the buffer zone between the threads during installation, providing a reliable fit and high exit torque.
The thread withdrawal torque reaches the IFI124 and 524 standards.
No additional locking settings such as washers or adhesives can reduce the possibility of looseness in vibration.
Increase (fastener) use occasion
The self-tapping triangular thread can be used in various drilling, punching and core holes of castings, thin iron sheets and hard plastics.
