It is commonly known that every industry has its own class clowns, and the fastener industry is no different. In fact, it has a special type of fastener referred to as the "class clown" or irregular part. These unique fasteners are distinct from the typical fasteners we are accustomed to and possess exceptional qualities. Even the most experienced master of the trade would not claim to know every aspect of these special fasteners. Let it be known that diversity and innovation are present in every corner of our diverse world.
Locking nut
The shape of the cardan nut is quite special. The square box contains a square nut. The square nut not only has a through hole, but also has a thread, which is suitable for guide rails and on-site assembly.
Top-to-top wave spring
Yes, as the name suggests, its appearance is like a wave, similar to the shape of a common cylindrical helical spring, and the wavy flat wire spirals from crest to crest.
Slotted anti-theft screw
These screws are similar to carriage screws, but they are different. There is a groove on the top, the vertical part is a cutting thread, and the end is pointed or conical. It is often used for the installation of metal, stone slabs, and plastic bench thin plates. Pin
Elastic cylindrical pin
Also known as a spring pin, it is generally a headless hollow cylinder with a serrated groove at the axis. Due to its good elasticity and shear resistance, it is mainly used for fixing, connecting, and fixing between parts.
Grommet nut
Washer nut is usually a threaded nut with a blind hole inside. It is usually used as interior parts for automobiles, ships, elevators, etc. to connect plates.
Precautions for using special fasteners
01 Pay attention to material details
For example, the first "gas stove" fastener - the card nut, its material is generally carbon steel and stainless steel. These two materials have their own advantages and disadvantages. They should be selected according to specific usage scenarios, budgets, etc., and making the best use of them is the first choice for connecting life!
02 Size is very important
Before installing special fasteners, be sure to clarify the size of the plate and the part to be fastened, and do not "mix and match"! Otherwise, seemingly minor problems such as loose bolts and broken bolts may trigger a series of butterfly effects and even safety accidents.
03 Master the installation method
Of course, the installation method of special fasteners is quite special, and special tools are often required for installation. This is when the professional quality and patience of the installer are tested. After the prefabricated holes are drilled, it is best to ensure that the surface of the special fasteners remains smooth and burr-free.
