Use Cases

For threaded component fastening

Pan head machine screws are used to fasten parts into pre-tapped holes or with matching nuts. They are suited to assembly, maintenance, repair, fabrication, equipment work, metalworking, and construction assembly.

How to Choose

Match the mating thread first

Confirm whether the assembly requires an inch thread, such as 1/4-20 or 5/16-18, or a metric thread, such as M3 x 0.5, M4 x 0.7, M5 x 0.8, or M6 x 1.0. Then select the required length, drive, material, and listed finish.

Applications

Support common assembly tasks

The range includes compact metric screws for component assembly, longer options for applications needing additional reach, and inch-size machine screws for compatible tapped holes and nuts.
