Steel Zinc Phillips Slotted Pan Head Screw

 

Steel zinc Phillips slotted pan head screws are made of high-quality carbon steel. The 11-slot pan head screws with color galvanized treatment achieve a perfect balance between cost and performance. The unique 11-slot design provides excellent torque transmission efficiency while maintaining a beautiful color appearance.

Material and processing technology:
Steel zinc Phillips slotted pan head screws are made of carbon steel (such as 1022A, 10B21, etc.). The surface hardness reaches HRC53 or above after carburizing heat treatment, and the core hardness is HRC32-40, which meets the requirements of national and American standards. The surface adopts environmentally friendly color zinc coating, which meets the EU RoHS standard, does not contain heavy metals and other harmful substances, and the anti-corrosion grade is Australian standard C4.

Multilayer electroplating process:
Base layer: 5-8μm zinc layer (salt spray test for 72 hours)
Surface layer: Color passivation film (blue and white/color zinc optional)
Sealing treatment: chromate sealing (enhanced corrosion resistance by 30%)
Innovative slot design:
Compared with the traditional cross slot, the eleven-shaped slot (Pozidriv):
The contact area is increased by 40%.
The anti-slip ability is improved by 60%
Applicable torque range: 0.8-4.5N·m (depending on the specification)
Professional use suggestions
