This article is related to the difference between nail and screw.
What is Nail?
Nail is the most common fasteners used in the field of construction. Up to the end of the Colonial time frame, all nails utilized in the world were handmade.
Normally, these nails were forged on an anvil from nail rods, which were sold in bundles.
These nail poles were arranged either by folding iron into little bars of a particular thickness or by the significantly more typical act of cutting plate iron into strips by methods for moving shears.
Nail is customized in a wide range of sizes, materials, and shapes, geared to a particular use or purpose Fastening with nail is the fastest and easiest way to connect wood members, requiring no predrilling or preparation, as they are driven into wood members with a hammer or a pneumatic gun.
Nail is frequently made of mild steel yet is accessible in a variety of other metals like aluminum, copper, zinc, brass, or stainless steel.
While the rest of the world measures a nail’s diameter and length in millimeters. In the United State Of America, they are measured in a term called pennies and designated as d.
A 2d nail is one inch (25 mm) long, a 6d nail is two inches (51 mm) long, and a 10d nail is three inches (76 mm) long. The two types most often used in construction are common nail and finish nail.
Common nail has flat heads are utilized in most construction framing and are not intended to be exposed to the environment.
A galvanized nail has a protective zinc coating on it to inhibit rust and corrosion. Finish nail is not meant to be seen; they have a tiny head and are utilized in finish woodwork such as casework and interior detailing.
Some other types of nails are box nails, casing nails, brad nails, roofing nails, cut nails, and concrete nails, each shaped differently in terms of its head, shaft, and point, to suit their particular use.
What is a Screw?
A screw might be characterized as a slanted plane folded over a nail and described by a helical edge.
It is a long metal shaft with threads circling along its length. It also has a turning where a screwdriver can be used to rotate the screw.
A screw normally has a head with a specially formed shape. The shape determines and heads size the size of the tool to be used to turn or drive the screw. Commonly used tools are wrenches and screwdrivers.
The underside part of the head is a shank that can be fully or partially threaded. A screw thread is a structure on a coned or cylindrical shape in the form of a helix.
The top of the ridge is known as a crest and the bottom root. The distance between the crest of one thread to the next one is known as a pitch.
Screws are tightened by rotating the tool anticlockwise or clockwise and are used for joining materials that don’t have existing holes in them.
The most common types of screws used in manufacturing are drywall screws, dowel screws, mirror screws, and concrete screws.
The strength of a screw relies on the width of the thread and the distance between them. However, the more numbers of the threads, the more rotations would be needed to attach the screw.
Also, if the continuous distance thread is wider, more force should be exerted on the tool in the rotations.
Screws are widely used in many applications. From the automobile industry to furniture, from air conditioners to kid’s remote control cars.
