PAN head Self-tapping Screws

PAN Head Self-tapping Screws - Efficient Thread Forming for Sheet and Light Metal Assembly

Product Features

• PAN Head Design: Provides a wide bearing surface to distribute clamping force evenly, supporting stable fastening on sheet metal and plastic components.
• Self-tapping Thread Geometry: Engineered to form mating threads directly in pre-drilled or thin materials, reducing the need for pre-threading operations.
• Material and Surface Options: Commonly manufactured from carbon steel or stainless steel, with surface treatments such as zinc plating or black oxide for corrosion management.

Product Description

PAN head self-tapping screws are manufactured in accordance with widely used fastener standards such as DIN and ISO, ensuring dimensional consistency and interchangeability in industrial supply chains. The thread profile is designed to cut or form internal threads during installation, supporting controlled torque application and repeatable fastening results. These screws are widely specified in applications requiring reliable fastening in thin-gauge metal, plastics, and composite materials, where production efficiency and assembly consistency are important considerations.

Applications

This product is commonly used in the following scenarios:

• Sheet metal fastening in electrical enclosures and control cabinets
• Assembly of household appliances and consumer electronics housings
• Light steel framing and HVAC component installation
• Plastic-to-metal or plastic-to-plastic fastening in industrial equipment

FAQ

1. Can PAN head self-tapping screws be used for stainless steel sheet applications?

Yes, when manufactured from appropriate materials and used within recommended thickness limits, PAN head self-tapping screws can be applied to thin stainless steel sheets. Proper pilot hole sizing and controlled installation torque are important to achieve consistent thread forming and reduce the risk of thread damage.

2. How do self-tapping screws reduce assembly time compared to machine screws?

Self-tapping screws eliminate the need for pre-threaded holes or separate tapping operations. By forming threads during installation, they simplify the fastening process, reduce tooling steps, and support faster assembly in high-volume production environments.
