White Head Screws Coloured Top Painted Head Phillips Pan Switch Machine Screws

White head screws are the screws with white or the other color powder painted. Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for the coating of metals, such as household appliances, aluminum extrusions, drum hardware, and automobile and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods. Ever Hardware provides custom-made fasteners and customizable packaging.
Advantages of Powder Coating instead of other coatings
1：Powder coatings emit near zero volatile organic compounds (VOC).
2：Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
3：Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid coated items.
4：The wide range of specialty effects is easily accomplished using powder coatings that would be impossible to achieve with other coating processes.

Phillips drive bits are often designated by the letters “PH”, plus a size code 0000, 000, 00, 0, 1, 2, 3, or 4 (by order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers.
