Analysis: Reasons for choosing triangular self-tapping screws for metal parts

The triangular self-tapping screw has a unique approximate triangular cross-sectional profile and provides embedded self-tapping and self-locking devices. Without any spring pads, the locking effect when vibration occurs can be improved, so the connection is more reliable, and expensive tapping devices and operations are saved, and direct costs are reduced.

Triangular profile facilitates thread forming

1. Ensure that the connection is complete; 2. Overcome the increase in friction; 3. Reduce the driving torque.

Complete thread projection surface

1. Improve product consistency; 2. Improve connection effect.

Reduce connection costs

The key to reducing connection costs is to remove those inefficient processes and unnecessary parts. When the triangular self-tapping screw is locked into the object, a suitable thread is automatically formed, and those expensive automatic tapping equipment and tapping procedures are no longer needed.

Eliminate expensive and time-consuming bottom hole tapping procedures and facilities

Improve assembly operations

When we install ordinary self-tapping screws, we often need a high torque value to overcome friction. The unique cross-sectional shape of triangular self-tapping screws is used to reduce friction. A relatively small torque is sufficient to install the screws in place. With the rotation of the triangular screw, a strong and rigid female thread is also formed.

Relieve thread wear and chip problems

Reduce the interference between threads

Provides uninterrupted plastic flow and improves connection integrity

Replaceable

The right to use the standard thread series can be replaced by machine screws.

The design allows the removal and replacement of fasteners

Prevent connection loosening during vibration

The mechanical and self-locking characteristics of the triangular self-tapping screw greatly improve the loosening ability under vibration conditions. A unique triangular outer contour allows the material to flow into the buffer zone in the middle of the threads during installation, thereby providing a reliable fit and high exit torque.

Thread withdrawal torque meets IFI124 and 524 standards.

Without additional locking settings such as washer and adhesive, the possibility of loosening under vibration can be reduced.

Increase (fastener) use occasions

The self-tapping triangular thread can be used in all kinds of drilling, punching and core holes of castings, thin iron plates and hard plastics.
