The Phillips pan head self tapping screws is a type of threaded fastener with a flat circular head and a Cross recess on the top. The rod part has Tapping thread. The pitch is relatively large and the tooth profile is deep. The tail part is conical or pointed.When inserting prefabricated holes or thin plates made of metals, plastics, woods, etc., it can rely on its own threads to squeeze or cut out the corresponding internal threads in the holes, without the need for pre-tapping or using matching nuts.The pan head design provides a large pressure-bearing surface.

The structure of this Phillips pan head self tapping screws can be divided into five functional areas: the head, the driving groove, the shaft, the thread, and the tail.
1.Pan Head
The head is in the shape of a low, cylindrical form, with the top surface being flat or slightly curved, and the edges being right angles or slightly chamfered.
The pan head provides a large pressure-bearing surface, which can evenly distribute the axial force during tightening to the surface of the fixed material, preventing the thin plate from deforming or crushing.
2.Cross Recess / Phillips
The slot is shaped like a cross, with a cone‑shaped bottom in the middle. The two slots run perpendicular to each other and open outward.
This cross design helps the screwdriver tip line up by itself while you’re tightening the Phillips pan head self tapping screws, so it doesn’t slip as easily. Compared to the flat slot, it can withstand higher tightening torque and is suitable for high-speed assembly with electric screwdrivers.
3.Tapping Thread
The helical tooth profile angle is mostly 60°, but the tooth tip is relatively sharp while the tooth base has a smooth arc transition.
4.Cone Point
The tail is conical in shape, with a cone angle of approximately 30° to 45°.

The inner bag is made of PE plastic bag and anti-rust paper. The outer box is a double-walled corrugated cardboard box. Each box has a net weight of 25 kg. It is fixed with pallet wrapping film and packing straps.
Sure. We’ve got 1 kg, 2 kg, and 5 kg plastic bags. Also boxes with 100, 200, or 500 pieces.
We really don’t recommend putting different sizes together in one box. But if you have to, we can pack them in plastic boxes with separate compartments or put each size in its own small bag. And we’ll clearly mark the sizes on each.
