A screw refers to parts for construction machinery. It is a kind of small cylindrical or conical metal rod with a threaded part with a sharp end like a nail. It has a slotted or dimpled head and is used alone.

Casing Nail.

A near relation of the finishing nail, the casing nail is slightly larger and has increased holding power. It is most often used for attaching moldings such as window and door casings where added strength is required.
The parts of the nail are the head, shank or shaft, point, and the gripper marks – slight grooves incised into the shank near the head of most (but not all) varieties of nails.
The nail functions by displacing wood fibers when it is pounded into the workpiece, and the pressure exerted against the shaft by the displaced wood provides the holding power.
Nails are sometimes referred to by casing nails length in inches, but more often the traditional terminology of the penny is used. Dating from the days when nails cost a lot more than they do today, the term penny identifies the size of a nail. In an earlier era, one hundred nails of a certain size cost three pennies; hence the name “threepenny nail.” One hundred nails of the next size cost four pennies, and so on. The pricing structure has long since been abandoned (today, nails are sold by the pound), but the nomenclature of the penny survives.

Application: Casing Nails Do for Interior & Exterior Decoration

Galvanized casing nails are similar to finishing nails but more robust and heavier with conical heads and thicker shanks for providing more holding powers.
The heads of casing nails allow the nails to be set flush with or just underneath the wood surface, as well as covered with putty or wood filler to make the nail unseen. Thereby, the nails are used where there is a strict demand of aesthetic effect.
With superior zinc plating, the casing nails perform excellently whether interior trimmings or exterior applications, for example:
Cabinet work and finish work.
Attach mouldings including window and door casing, etc.
Exterior casing such as cornices.
Interior trimmings such as crown moulding and wall niches.
