Phillips Pan Head SEMS Screws.

What are Phillips Pan Head SEMS Screws?

Phillips pan head SEMS screws are advanced integrated fasteners that combine a pan head screw, Phillips drive and one or more captive washers, typically a flat washer, spring washer, or both.

By merging these components into a single unit, these screws simplify assembly, reduce part handling and eliminate the need for loose washers.

This design is particularly beneficial in high-speed manufacturing environments, such as electronics and automotive assembly, where precision, component control and efficient assembly are critical.

How Phillips Pan Head SEMS Screws Work

Phillips pan head SEMS screws function by retaining washers on the screw shaft during production, ensuring they stay in place throughout handling and installation. This eliminates the need for separate washer alignment, streamlining the assembly process.

The pan head offers a broad, low-profile design for load distribution, while the Phillips drive allows for secure torque application with compatible tools. This makes Phillips pan head SEMS screws ideal for automated environments where reliability and efficiency are paramount.

Materials Phillips Pan Head SEMS Screws Are Made From

Accu’s Phillips pan head SEMS screws are manufactured from stainless steel (A2-50), offering high strength and corrosion resistance, perfect for industrial and assembly-line applications. The captive washers are also made from A2 stainless steel, ensuring long-lasting durability and material compatibility.

This material combination guarantees consistent performance in both indoor and outdoor environments, with strong resistance to vibration and corrosion.

For additional resistance against vibrations, this range of screws can be purchased with thread lock patches pre-applied to further reduce assembly steps and reduce chances of loosening.

Sizes and Types of Phillips Pan Head SEMS Screws Available

Accu supplies Phillips pan head SEMS screws in metric thread sizes ranging from M2 (2mm) to M6 (6mm), with lengths between 4mm and 50mm. Each screw features a Phillips drive, allowing for efficient installation using a standard Phillips screwdriver or compatible tools.

FAQs

Q: What makes Phillips pan head SEMS screws different from other SEMS screws?

A: The main difference lies in the combination of the pan head and the Phillips drive. This provides a low-profile head for even load distribution and allows for easy installation with a Phillips screwdriver.

Q: Can Phillips pan head SEMS screws be used in high-vibration environments?

A: Yes, particularly when configured with spring washers. These washers offer added resistance against loosening, making the screws ideal for dynamic or vibration-prone environments.

Q: Are Phillips pan head SEMS screws suitable for automated assembly?

A: Absolutely. Their integrated design reduces component count, streamlines the assembly process and is highly compatible with automated systems.

Q: Can Phillips pan head SEMS screws be reused?

A: Yes, so long as there is no visible damage to the screw or washers. The spring washer may lose tension over time and should be checked for wear before reinstallation.
