Screw Description

^{A fastener or fastening is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components.Welding is an example of creating permanent joints. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel.}

^{What are the types of fasteners?}

^{Specific types of Fasteners and its uses:}

^{· These are supposed to be threaded lengths made of steel rods with heads on single end.}

^{· Bolts are generally used along with nuts at other end and every so often with a washer too.}

^{· Bolts are of four types including carriage bolt, Cap screw, hex bolts and Plow bolts.}

^{What is screw fastening?}

^{An externally threaded fastener that has thread form which prohibits assembly with a nut having a straight thread of multiple pitch length is a screw. (Example: woodscrews, tapping screws.)}

^{What are the different steel fastening products?}

^{Fasteners are often made of steel, but there are many different types of steel. Here are the steels most commonly used for fasteners: Alloy steels: Steels alloyed with molybdenum, nickel, and chromium (AISI 4037, 4130, 8630) are best if strength is required.}

^{Is a bolt a fastener?}

^{A bolt is a form of threaded fastener with an external male thread. Bolts are closely related to screws.}

^{Why are fasteners coated?}

^{Zinc is one of the most common coatings for most fasteners mainly due to the fact that it's cheap and protective. It is mainly used to protect the fasteners from oxidative damage, such as rusting of susceptible metals.}

^{What are special fasteners?}

^{Special fasteners are a bolt used under industrial circumstances to hold pieces heavy weight industrial components together under extreme pressure. These screws are made out of materials highly resistant to corrosion.}

^{What are the types of screws?}

^{There are two basic types of sheet metal screws, self-tapping screws and self-drillingscrews}

^{What do screws screw into?}

^{Screws are one kind of simple machines. ... The head is specially shaped to allow a screwdriver or wrench to grip the screw when driving it in. The most common uses ofscrews are to hold objects together — such as wood — and to position objects. Oftenscrews have a head on one end of the screw that allows it to be turned.}

^{What are the different types of screws?}

^{Screw Head Types}

^{Screws come with different types of heads, including the flat head (-) and Phillips head (+), as well as hex head (shaped like a hexagon), and Torx head (shaped like a six-pointed star)}

^{What are metal fasteners?}

^{Metal Fasteners. Metal fasteners are of two kinds—those producing a permanent bond and those requiring either a releasable or a sliding bond. Screws, nuts and bolts, rivets, retaining rings and clamps are examples from the first category.}

^{Are nails fasteners?}

^{Nails are most commonly used to fasten pieces of wood together, but they are also used with plastic, drywall, masonry, and concrete. Nails are usually made of steel but can also be made of stainless steel, iron, copper, aluminum, or bronze.}

^{What is difference between bolt and screw?}

^{Screws are generally turned into an object, like a piece of wood, so the head needs to be bigger than the surface. ... The shafts of bolts are not tapered, whereas manyscrews are tapered. The main difference between a bolt and a screw is that a typicalscrew can work on its own and a bolt requires a nut to secure it}

^{Why are washers coated with zinc?}

^{Zinc coatings prevent corrosion of the protected metal by forming a barrier, and by acting as a sacrificial anode if this barrier is damaged. When exposed to the atmosphere, zinc reacts with oxygen to form zinc oxide, which further reacts with water molecules in the air to form zinc hydroxide.}

^{What is the most common screw size?}

^{What's The Most Common Size? A screw's diameter is called its gauge. The most common gauges are between 2 and 16 in diameter. An 8-gauge screw is a good general-purpose size.}

^{Why are there different types of screw heads?}

^{Torque and stripping}

^{Although slotted head and Phillips head screw drives are common and effective, they both suffer from slipping and stripping. ... They are also much less likely to strip, which is a problem for Phillips screw drives. There are so many screw head typesthat we could spend all day talking about them.}

^{What are mechanical fasteners?}

^{A mechanical fastener is a device that is used to mechanically join (or fasten) two or more objects together. There are many different types of mechanical fasteners, but, in general, fasteners can be divided into two main categories; non-permanent and permanent fasteners}

^{Is zinc coating the same as galvanized?}

^{When used on bolts, due to the thickness of the zinc coating, all galvanized nuts must be tapped oversize. Zinc plating or electroplating is a process where zinc is applied by using a current of electricity. It is a thinner coating than hot dip galvanizing making it unsuitable for outdoor applications.}
