Screw material and finish
Finishes and materials are the characteristics of screws and sometimes determine what the fastener is made for. Some materials allow a screw to manage demanding jobs, while others help to avoid corroding or rusting. When the screw’s material is prone to rust, some finishes can protect it from corrosion. The ideal screw material is steel, but it also experiences decay when exposed to moisture. For some reason, a steel screw needs a plating or coating that helps to protect it from corrosion. The known finishes and coatings include zinc plating and black phosphate. Some finishes, like electro-coated paint, polymer, and ceramic, are available. There are finishes like nickel plating, chrome, and brass features as protection against corrosion. But they are not recommended for outdoor applications. Bright steel screws will not have any corrosion resistance, and it is made for interior applications where moisture is not a problem.

Other crowns like bugle-head and flat head screws are made to rest flush with the workpiece’s surface. There are some self-countersinking screws where it can cut the countersunk hole while you are driving them. Except for the countersunk screw varieties, some non-countersunk screws have round or pan heads that sit on the surface. Some trim-head screws have tiny heads so that you can cover them compared to other fasteners. Some screws have washer heads, truss heads, and wafer heads. It will give a more prominent place of contact underneath the head of the screw compared to other fasteners.

You can remove and install screws with coarse threads other than faster. When the screw has a fine line, it is meant to be used with nuts or for pre-tapped holes. The smaller gaps between every thread give the screws a tighter hold, but removing and installing them will take longer.
