phillips recess pan head self tapping screw

Pan head self-tapping screws are used wherever a reliable and convenient fastening solution is needed. Unlike self-drilling screws, which can be used through metal, self-tapping fasteners are suitable for use with softer materials such as wood, and only need an appropriate driver to use. Self Tapping Pan Head Metal Screws do not need a pilot hole drilled to operate effectively. As Ss Pan Head Self Tapping Screw are made of stainless steel, they are suitable for specialist environments such as food and catering industries. Ss Pan Head Self Tapping Screw

SS304 and SS316 stainless steel Pan Head Tapping Screws are commonly used in various applications due to their superior corrosion resistance and strength. Here is a description of these screws:

1. Material: SS304 and SS316 stainless steel are both austenitic grades of stainless steel. SS304 is made up of 18% chromium and 8% nickel, while SS316 contains 16% chromium, 10% nickel, and 2% molybdenum. This composition enhances their resistance to corrosion, making them suitable for use in harsh environments, including marine and chemical applications.

2. Head Style: These screws feature a pan head design, which is rounded and slightly flattened, resembling the shape of a pan. The large diameter and low profile of the head provide a wide bearing surface, distributing the load evenly and reducing the risk of surface damage.

3. Tapping Capability: Pan head tapping screws are specifically designed for creating threads in pre-drilled or punched holes in various materials, including metal, plastic, and wood. They have a sharp, self-tapping point that enables easy insertion and secure fastening without the need for a pre-tapped hole.

4. Thread Type: These screws typically have a coarse thread pitch, allowing for quick installation and high pull-out strength. The thread extends along the entire length of the screw, ensuring a secure hold and preventing loosening over time.

5. Size Range: SS304 and SS316 stainless steel pan head tapping screws are available in various sizes and lengths, allowing for versatility in different applications. The size is usually specified by the diameter and length of the screw, such as #8-32 x 1" or M4 x 20mm.

6. Applications: Due to their corrosion resistance and durability, SS304 and SS316 stainless steel pan head tapping screws are commonly used in outdoor and marine environments, as well as in industries such as construction, automotive, and electronics. They are ideal for fastening metal sheets, brackets, hinges, and other components that require a secure and long-lasting connection.

Overall, SS304 and SS316 stainless steel pan head tapping screws are reliable fasteners that provide excellent corrosion resistance, strength, and versatility in various applications.
