🔩 M4 Phillips Pan Head Machine Screws – A2 Stainless Steel, Fully Threaded (4mm–100mm Lengths)

You’re assembling an electronic enclosure, mounting a hinge, or repairing a piece of outdoor furniture – and you need a reliable, corrosion‑proof M4 screw. These Phillips pan head machine screws are made from A2 stainless steel (304), so they won’t rust indoors or out. The low‑profile pan head provides a wide bearing surface, ideal for plastic, sheet metal, and wood. Phillips drive works with standard crosshead screwdrivers. Choose from lengths 4mm up to 100mm (measured under the head). Fully threaded for maximum grip in shallow holes. Perfect for 3D printers, boat fittings, automotive trim, and everyday DIY.

✨ Key Features – M4 Pan Head Phillips Screws (A2 Stainless)

❓ Frequently Asked Questions – M4 Pan Head Phillips Screws

1. How do I measure the length of a pan head screw?

For pan head screws, the length is measured from the underside of the head (the flat bearing surface) to the tip. The head itself is NOT included. So an “M4 x 10mm” screw has a 10mm long threaded shaft under the head. All lengths in our listing follow this standard.

2. Are these screws fully threaded? What about longer lengths like 100mm?

Yes – all M4 screws up to 100mm length are fully threaded from under the head to the tip. This gives you maximum grip in blind holes or through‑nut applications.

3. Can I use these screws outdoors or in saltwater?

A2 stainless (304) is highly corrosion‑resistant and suitable for outdoor use, including garden furniture, coastal areas, and freshwater marine applications. For continuous saltwater immersion, we recommend A4 (316) stainless, but for most general outdoor use, A2 is excellent and will not rust.

4. What Phillips screwdriver size do I need for M4 screws?

For M4 screws, a #1 or #2 Phillips screwdriver works best. A #2 is more common and provides good engagement. Always use a driver that fits snugly to avoid cam‑out and head damage.

5. Can I use these screws with a nut? What size nut fits M4?

Yes – these are machine screws. Use a standard M4 metric nut (0.7mm pitch). They will also thread into pre‑tapped M4 holes. They are not self‑tapping, so for wood or plastic, drill a pilot hole and use a nut or threaded insert.

6. Do you sell other lengths like 3mm or 110mm? And what about M4 nuts?

Lengths from 4mm to 100mm are available in this listing. For lengths outside this range (e.g., 3mm or 110mm), please contact us – we may be able to supply them. We also sell M4 stainless nuts separately – check our store.
