M30 M33 Heavy Duty Hex Metal Nut HEXAGON THIN MetalNUT SS304 SS316
for High-Strength Applications
Product Description:
Hexagonal nuts and screws, bolts, screws used in conjunction with
each other, to connect the role of fastening machine parts. One of
the most widely used by the 1 type of six nuts, C nuts for surface
roughness, the precision requirements of the machine, equipment or
structure is not high; A and B nuts for the surface is more
polished, the precision requirements of the machine, equipment or
structure. 2 type hexagonal nut thickness M is thicker, more often
used for often need to be mounted and dismounted on the occasion.
Thin hexagonal nuts are thinner in thickness M, and are mostly used
on occasions where the surface space of the connected machine parts
is restricted.
Hexagonal nuts in accordance with the nominal thickness is divided
into I type, II type and thin three kinds of nuts above level 8 is
divided into 1 type and II type two types. I type hexagonal nuts
are the most widely used, 1 type of nut is divided into A, B, C
three levels, of which A and B level nuts are suitable for surface
roughness is small, the precision requirements of the machine,
equipment and structure of the high level, while the C level nuts
are used for the surface of the rougher, the precision requirements
of the machine, equipment or structure; C level nuts for rough
surface, the precision requirements of the high level. The
thickness of type 2 hexagonal nuts is thicker, and they are mostly
used in the occasions that need to be assembled and disassembled
frequently.
The design of hexagonal nuts gives them good torque transmission
capacity and can withstand large axial and radial loads.
1. Construction:In the construction industry, hexagonal nuts are
commonly used in the connection of steel structures, steel frames
and bridges to ensure the stability and safety between structural
components.
2. Mechanical engineering: In the field of mechanical engineering,
hexagonal nuts are used to fix various parts of mechanical
equipment, such as automobiles, ships, aviation and machine tools,
etc., in order to ensure the normal operation and long-term
stability of the equipment.
3.Electronics:Some electronic products use snap screws, which are
actually a special type of hexagonal bolt, to ensure the tightness
and stability of electronic components.
4. Home maintenance:In daily life, hexagon nuts are also often used
in furniture assembly, bicycle repair and other home maintenance
work.
In addition, hexagon nuts have a variety of classifications and
specifications to meet different engineering needs. For example,
category 1 hexagon nuts have single-sided chamfers, while category
3 hexagon nuts have double-sided chamfers. Pocket nuts, which have
screw holes that do not run through their profile, are commonly
used for decorative purposes, especially in applications such as
playground equipment where the unterminated end of the bolt may be
a hazard. Butterfly nuts, on the other hand, are commonly used in
applications where space is limited, such as on automobile wheels.
Applications
The M30 and M33 heavy-duty hex nuts, designed with thin profiles
and made from premium SS304 and SS316 stainless steel, are ideal
for high-strength applications that demand robust, long-lasting
components. These hex nuts are engineered to meet the stringent
requirements of industries where heavy loads and high torque are
frequent, such as construction, manufacturing, and engineering. The
SS304 and SS316 stainless steel materials provide superior
corrosion resistance, making these nuts well-suited for outdoor
environments, extreme weather conditions, or marine and chemical
environments.
The hexagonal shape of the nut allows for easy and efficient
installation with standard wrenches, providing a secure, tight fit
that prevents loosening under vibration or pressure. The thin
design of these nuts offers an advantage when space or weight is a
concern while still maintaining excellent strength and durability.
The SS304 stainless steel offers resistance to oxidation, rust, and
corrosion, making these nuts a reliable choice for environments
where exposure to water, chemicals, or other harsh elements is
common. For even more demanding environments, SS316 provides
enhanced resistance to corrosion, including resistance to chlorides
and acids, making it the go-to choice for marine and industrial
applications.
These heavy-duty hex nuts are widely used in applications like
heavy machinery, equipment, and structural connections, offering
the necessary strength to hold components together under
substantial stress. Their ability to withstand extreme temperatures
and environmental conditions makes them indispensable in ensuring
the safety, performance, and longevity of mechanical systems. When
reliability and strength are essential, the M30 and M33 stainless
steel hex nuts provide a high-performance, cost-effective solution.
