Hex Bolts: Applications and Advantages
Hex bolts are widely used across various industries and products
due to their simple design, high strength, and ease of
installation. Below are some key applications and advantages of hex
bolts:
Industries and Products That Use Hex Bolts
1. Construction Industry
- Hex bolts are commonly used in structural steel connections, such
as bridges, building frameworks, and scaffolding. Their ability to
handle heavy loads and external forces like wind ensures stability
and durability in construction projects.
2. Machinery Manufacturing
- In machinery and equipment assembly, hex bolts are essential for
fastening mechanical parts in machinery such as lathes, heavy-duty
equipment, and assembly lines. Their high strength and durability
make them suitable for machines operating under vibration and heavy
loads.
3. Automotive and Transportation
- Hex bolts are widely used in the automotive industry for securing
critical parts like chassis, engines, and transmission systems.
Their strength and reliability help maintain the vehicle's
integrity under high-speed and heavy-duty conditions.
4. Home Appliances and Electronics
- Hex bolts are used to assemble and secure parts in appliances
such as air conditioners, washing machines, and televisions. They
provide reliable connections and ensure the overall stability of
the products.
5. Energy and Petrochemical Industry
- Hex bolts are crucial in wind turbines, nuclear power plants, and
petrochemical plants, where they are used in securing large
equipment and pipeline systems. Their corrosion resistance and
strength allow them to perform in harsh environments.
6. Marine and Offshore Engineering
- In shipbuilding and offshore platforms, hex bolts are used to
secure deck fittings, hulls, and equipment. Stainless steel hex
bolts, in particular, resist corrosion from seawater, ensuring the
longevity of marine structures.
7. Furniture Manufacturing
-Hex bolts are frequently used in the assembly of furniture such as
beds, tables, chairs, and cabinets. Their easy installation and
firm fastening provide stability and long-term durability to
household and office furniture.
Applications:
Hot plating and electroplating are two different metal surface
treatment technologies, the main differences are as follows:
Hot Plating:
Process: Zinc-iron alloy plating is formed by immersing metallic
zinc in molten state into the surface of the workpiece at a higher
temperature.
Characteristics: Thick plating, strong adhesion, effective
resistance to corrosion and abrasion, good electrical and thermal
conductivity.
Application: Commonly used for industrial products in outdoor
environment, such as bridges and highway guardrails.
Electroplating:
Process: Using the principle of electrolysis, a uniform, dense,
well-bonded metal film is deposited on the metal surface.
Features: precise control of plating thickness, uniform plating,
corrosion resistance, stable process, simple operation.
Application: Widely used in automotive, electronics, aviation and
other fields, it can produce a variety of different metal coatings,
such as galvanised, chromium plated, gold plated and so on.
The production process mainly includes: preparation of the original
plate → pre-plating treatment → hot dip plating → post-plating
treatment → finished product inspection.In accordance with the
customary often according to the different methods of pre-treatment
of hot-dip galvanising process is divided into two categories of
off-line annealing and in-line annealing.Outside the line annealing
is hot-rolled or cold-rolled steel into the hot-dip galvanising
line before the first in the bottom of the annealing furnace or
cover-type annealing furnace for recrystallisation annealing, so
that the galvanising line does not exist annealing process.The
steel sheet must be maintained with a clean, pure iron active
surface free from the presence of oxides and other dirt prior to
hot-dip galvanising.This is achieved by removing the iron oxide
from the annealed surface by pickling, followed by a protective
coating of a solvent consisting of zinc chloride or a mixture of
ammonium chloride and zinc chloride, which prevents the steel sheet
from being re-oxidised.The hot-dip galvanising methods that fall
into this category include: wet hot-dip galvanising, sheet steel
method and Wheeling hot-dip method.The wet process involves hot-dip
galvanising the surface of the steel sheet without drying the
solvent (i.e. the surface is still wet) into a zinc bath covered
with molten solvent.The disadvantages of this method are:
galvanisation can only be carried out in a lead-free state, the
alloy layer of the coating is very thick and the adhesion is very
bad.Generated zinc dross are accumulated in the zinc and lead
liquid interface and can not be deposited on the bottom of the pot
(because the specific gravity of zinc dross is greater than the
zinc liquid and less than the lead liquid), so that the steel plate
because of the zinc layer through the contaminated
surface.Therefore, this method has been basically eliminated.
