DIN968 Zinc Treatment Cross Pan Head With Washer Self-tapping Screws

1.Products Details:

PWA cross - recessed pan - head self - tapping screws with washer and teeth are a type of fastener. The "P" in PWA represents the pan - head, "W" represents the washer, and "A" indicates the self - tapping thread. These screws are usually made of carbon steel or stainless steel, and can have surface treatments such as nickel - plating or galvanization. They are designed to be directly screwed into materials like metal, wood, or plastic without pre - drilling holes, forming internal threads by self - tapping, and achieving a firm fixing effect.

2.Key Features:

- Easy to Install:

With a cross - recessed design on the head, they can be easily driven by a cross - head screwdriver or an electric screwdriver, featuring flexible angle adjustment and high installation efficiency.
- Washer Design:

 The built - in washer increases the contact area with the fastened material, which can evenly distribute pressure, prevent the screw head from sinking into the material surface, and enhance the fixing stability.
- Self - Tapping Function:

The thread is sharp and has a self - tapping feature. It can penetrate the material and form threads by itself, simplifying the installation process and being suitable for various non - threaded hole materials.
- Tooth Design:

The teeth on the screw can enhance the gripping force, making the screw more firmly fixed in the material, reducing the possibility of loosening, and improving the mechanical connection strength.
- Good Versatility:

 They can be used in a variety of scenarios, such as furniture manufacturing, construction, and electronic equipment assembly, and are suitable for fixing different materials.
- Corrosion Resistance:

When made of stainless steel or through surface treatments like nickel - plating and galvanization, they have good corrosion resistance, which can be used in different environmental conditions and has a long service life.
