Pan head SEMS screws offer a broad, rounded head profile for excellent bearing surface and a clean appearance in finished assemblies. They are the most common SEMS machine screw type.
The integrated captive washer—whether flat, lock, or star-type, etc enhances load distribution and helps resist loosening during use.
Popular in electronics, appliance assembly, and general manufacturing, these screws are designed for efficient, repeatable fastening in both manual and automated setups.
