Countersunk head/Raised countersunk head/bugle head/pan head/round head washer/flat round head drywall screws

Countersunk, raised-countersunk, trumpet, pan head, round head washer and oval head drywall screws are commonly used fasteners in the fields of construction, decoration and industry. They have a variety of specifications and materials, suitable for installation needs in different scenarios. These nails are widely used in gypsum board, woodworking, light steel keel, wall decoration and other purposes according to the different head shapes.
The head design of the countersunk nail allows it to be completely embedded in the material's surface without leaving any protruding parts, which is suitable for occasions that require a flat surface, such as furniture manufacturing and interior decoration. Raised-countersunk nails partially expose the surface, which is convenient for subsequent processing or installation of other parts. Trumpet head nails can provide higher fixing strength due to their unique double-thread design, and are suitable for scenes with heavy loads, such as heavy partition board fixing.
The head of the pan head nail is round or hexagonal, which is easy to install with a wrench. It is often used in metal structures or connections that require higher strength. Round head washers and oval head nails are suitable for specific assembly needs due to their head shape, such as furniture assembly or mechanical equipment fixing.
These nails are usually made of high-strength steel and undergo surface treatment processes such as galvanizing and phosphating to improve corrosion resistance and service life.
