A fastener is a hardware device that
mechanically joins or affixes two or more objects together.
Fasteners can also be used to close a
container such as a bag, a box, or an envelope; or they may involve keeping
together the sides of an opening of flexible material, attaching a lid to a
container, etc. There are also special-purpose closing devices, e.g. a bread
clip. Fasteners used in these manners are often temporary, in that they may be
fastened and unfastened repeatedly.
Some types of woodworking joints make use
of separate internal reinforcements, such as dowels or biscuits, which in a
sense can be considered fasteners within the scope of the joint system,
although on their own they are not general purpose fasteners.
Furniture supplied in flat-pack form often
uses cam dowels locked by cam locks, also known as conformat fasteners.
Items like a rope, string, wire (e.g. metal
wire, possibly coated with plastic, or multiple parallel wires kept together by
a plastic strip coating), cable, chain, or plastic wrap may be used to
mechanically join objects; but are not generally categorized as fasteners
because they have additional common uses. Likewise, hinges and springs may join
objects together, but are ordinarily not considered fasteners because their
primary purpose is to allow articulation rather than rigid affixment.
Other alternative methods of joining
materials include: crimping, welding, soldering, brazing, taping, gluing,
cementing, or the use of other adhesives. The use of force may also be used,
such as with magnets, vacuum (like suction cups), or even friction.
Fasteners are used for fastening and
application of a very broad class of mechanical parts. In all kinds of
machinery, equipment, vehicles, ships, railways, bridges, buildings,
structures, tools, equipment, instruments and supplies, such as the above, you
can see a wide variety of fasteners. It is characterized by many different
specifications, performance of different purposes, and standardization,
serialization, GM seed is also very high degree. Therefore, it was also the existing
national standards for a class called fasteners standard fasteners, or simply
standard parts. Fasteners are the most widely used machine parts. With China's
accession to the WTO in 2001 and entered the ranks of the international trading
nation. China's fastener products are exported to countries around the world,
the world's fastener products are constantly influx of Chinese market. As one
of the fasteners import and export volume of larger products, to achieve
international standards, to promote Chinese enterprises to the world of
fasteners, fastener enterprises to promote the full participation of
international cooperation and competition, with all the important practical
significance and strategic significance. Due to the specific requirements of each
specific fastener product specifications, dimensions, tolerances, weight,
performance, surface condition, marking methods, and acceptance inspection,
marking and packaging projects.
We supply big range of such fastener.
