Phillips Pan Head Self Tapping Screw

The phillips pan head self tapping screw features a sharp point and specially designed threads that cut or form mating threads directly into materials such as sheet metal, plastic, or wood without pre-tapping. This capability eliminates a production step, speeding up assembly in automotive body panels, motorcycle plastic trim, electrical enclosures, and light-gauge structures. Using a Phillips pan head self-tapping screw simplifies processes, reduces equipment requirements, and lowers overall assembly costs in high-volume manufacturing.

Self-tapping screws are divided into two main categories: thread-cutting screws (e.g., AB, BP types) with chip-clearing grooves for thicker metals, and thread-forming screws (e.g., TA, TB types) that displace material for a tighter seal in thin sheets. The phillips pan head self tapping screw typically has a 60° thread angle with an optimized pitch and height for high retention and vibration resistance. Our products are manufactured to ISO 1478 and ISO 2702 standards for consistent performance.

Common sizes range from ST2.2 to ST8.0. Core products use case-hardened carbon steel with a surface hardness greater than HV450 and a tough core, finished with zinc plating, phosphating, or Dacromet. We also offer A2 stainless steel for corrosive environments. The Phillips pan head provides a broad bearing surface and a compatible drive for standard Phillips screwdrivers or bits, ensuring quick and secure installation.

In automotive wiring harness mounting, motorcycle fender installation, or cabinet assembly, the phillips pan head self tapping screw can improve line efficiency by over 30% by combining drilling and fastening in a single operation. Our screws undergo precise heat treatment to balance point hardness and thread strength, preventing breakage during driving. Choose our Phillips pan head self-tapping screw for consistent thread-forming performance and reliable connections that help control total production costs.
