News - What is the difference between triangular self tapping screws and ordinary screws？

In industrial production, building decoration, and even daily DIY, screws are the most common and indispensable fastening components. However, when faced with a wide variety of screw types, many people are confused: how should they choose? Among them, the triangular self tapping screw, as an efficient special fastener, has significant differences from ordinary screws. Understanding these differences is crucial for improving work efficiency and ensuring connection quality.

Core difference: Philosophical difference between tapping and fastening

The fundamental difference is that ordinary screws are usually used for "assembly", while the core function of triangular self tapping screws is to integrate "tapping" and "fastening".

Ordinary screws, we usually refer to mechanical screws, which need to be screwed into pre drilled threaded holes. Its function is to provide strong clamping force, firmly connecting two or more components with pre-set threads together. If ordinary screws are forcibly screwed into a non threaded substrate, not only will it fail, but it is also highly likely to damage the screws or substrate.

And the triangular self tapping screw is a pioneer. Its uniqueness lies in the triangular cross-section of its threads. When it is screwed into the material, the edges of the triangle will act like a tap, squeezing and cutting matching threads inside the substrate (such as plastic, thin steel plate, wood, etc.). This process achieves one-step "tapping" and "tightening", eliminating the tedious process of pre tapping and greatly improving production efficiency.

Performance advantages: anti loosening, high torque, and applicability

The triangular design of self tapping screws with triangular teeth brings several core advantages. Firstly, it has excellent anti loosening performance. Due to the tight triangular contact surface between the screw thread and the thread formed by compression inside the substrate after screwing in, this structure can generate huge frictional force and mechanical interlocking effect, effectively resisting loosening caused by vibration, especially suitable for occasions with frequent vibration, such as electrical products, automotive parts, etc.

Secondly, it has higher driving torque. The design of the triangular teeth ensures that the screw is subjected to more uniform force during the screwing process, and can withstand greater torque without slipping or damage, ensuring the reliability of the connection.

In contrast, ordinary screws usually require additional accessories such as spring washers and locking nuts for vibration resistance. Its advantage lies in its ability to be disassembled repeatedly. For equipment that requires frequent maintenance and adjustment, using prefabricated threaded holes with ordinary screws is a more suitable choice.

The choice of screw ultimately depends on your application material and requirements. But if you are pursuing ultimate production efficiency and stable and reliable connection effects, then triangular self tapping screws are undoubtedly your ideal partner.

The triangular self tapping screw combines two processes into one, saving you valuable time and labor costs directly, making the production line one step ahead.

Faced with the widely used thin-walled metals and engineering plastics in modern industry, triangular self tapping screws can provide unparalleled fastening force compared to ordinary screws, eliminating the troubles of slipping and loosening.

In summary, although screws are small, they are a crucial factor in determining product quality and production efficiency. Don't let traditional fastening methods limit your imagination and competitiveness anymore! When your project involves materials such as plastic and thin sheets, and you pursue efficiency and vibration resistance, choosing triangular self tapping screws is choosing a smarter and more reliable solution.
