Phil Pan Head Machine Screw — Metric Sizes
What Is a Phil Pan Head Machine Screw?
A Phil pan head machine screw is a fully threaded fastener with a low, rounded head that has a wide, flat underside and a Phil cross recess drive. The pan shape sits close to the surface while still leaving enough height for a firm driver bite, and the broad bearing face spreads the clamp load so the screw seats cleanly without digging in. The Phil recess self centers the bit, which keeps driving quick and square and makes it a strong fit for powered assembly. These screws show up everywhere from electronics and enclosures to brackets, panels, and general machine work, and are offered in plated steel and A2/A4 stainless.
Key Features and Benefits
- Low Rounded Pan Head: The low profile keeps the head close to the surface while the rounded top gives a clean, finished look.
- Wide Bearing Face: The broad flat underside spreads clamp load for a secure seat without marking the surface.
- Phil Cross Recess: The cross recess self centers the driver for fast, square driving by hand or power tool.
- Full Thread Engagement: Threaded to the head for a strong hold in tapped holes, inserts, and nuts.
- Steel and Stainless Options: Plated steel for general use and A2/A4 stainless for corrosion resistant service.

Frequently Asked Questions (FAQs)
1. What is a Phil pan head machine screw used for?
It is used for general assembly work such as electronics, enclosures, brackets, panels, and machine parts where a low rounded head and a fast centering cross recess drive are wanted.
2. What does pan head mean?
A pan head is a low, rounded head with a wide flat underside. It sits close to the surface and spreads the clamp load over a broad area for a clean, secure seat.
3. Why choose a Phil recess drive?
The Phil cross recess self centers the bit, which keeps the driver square and makes driving fast, especially with power tools. It is a good all round choice for volume assembly.
4. Are these screws available in stainless steel?
Yes. We stock them in A2 and A4 stainless, along with zinc plated steel and brass, for general, indoor, and corrosion resistant applications.
5. What thread type do these screws use?
They use standard metric coarse thread and mate with tapped holes, threaded inserts, or nuts of the same specification.
6. Can I drive these with a power tool?
Yes. The self centering cross recess suits powered driving. Match the bit size to the recess and keep steady downward pressure to avoid cam out.
7. What is the difference between pan head and round head?
A pan head is lower and flatter on top with a wider bearing face, while a round head is taller and more domed. The pan head gives a lower profile and a broader seat.
8. What sizes do you stock for Phil pan head screws?
We stock M2 through M8 in metric coarse thread, in plated carbon steel, brass, and A2/A4 stainless steel.
