High-Quality M12 & M20 Nylon Dome Cap Nuts Plastic Acron nuts Custom Black white Nuts

 
Product Description:

Cap nuts are used in the same way as hexagonal nuts. They are characterised by the fact that the main nut does not slide easily, but can only be tightened with a live spanner, a dull spanner, a dual-purpose spanner (open part) or a special square-hole socket spanner.
They are mainly used for rough and simple parts, in tyres and front and rear axles of cars, tricycles, electric cars, etc. They are also used for fixing the bases of road light frames and some mechanical equipments which are often exposed to sunlight and rain.

1, hexagonal nuts?
Hexagonal nuts are mainly used with bolts and screws to connect fasteners. According to the nominal thickness is divided into I type, II type and thin three kinds of nuts, more than 8 levels of nuts are divided into I type and II type two types, I-type nuts are divided into A, B, C three levels.

Applications
Among them, A level and B level nuts are suitable for small surface roughness, high precision requirements of machines, equipment and structures, while C level nuts are used for surface roughness, high precision requirements of machines, equipment or structures; II type hexagonal nuts are thicker, more often used in the occasions that need to be mounted and dismounted.

2, what is a square nut?
Because of its square shape, it is also known as a square nut, also known as a square nut or square nut. Square nut is a kind of welded nut, which is a kind of metal melted by high temperature and then welded in the middle of two products to play the role of fastening.

Applications
The fastening effect of this connection will be very good, will not be easy to loosen, is widely used in road traffic, home building materials and other industries. Almost covers all areas of fastener needs, is one of the common mechanical fasteners.

Applications

Machined Nylon (PA) Properties and Grades

Nylon (PA) is known for its high crystallinity, which produces strong, strain-resistant components. In addition, the use of nylon reduces the need for extensive lubrication, reduces noise and eliminates wear, corrosion and theft problems.

There are two common grades of nylon 6 and nylon 6/6 nylon that are noteworthy for their properties and uses. They can be used interchangeably in a variety of applications with some property differences.

Nylon 6 is commonly produced in two forms: a high-strength type for textile applications and a high-strength type for industrial use. It is usually formed into filament yarns and staple fibres. Most often, this nylon is used for tyre cord, parachutes, ropes or industrial cord. Similar to Nylon 6, Nylon 6/6 has many industrial uses, from thin-walled parts to large, thick-walled bearings. It is also an excellent candidate for metal replacement.

Advantages of nylon: High mechanical strength, good toughness, and high tensile and compressive strength.
Its tensile strength is higher than metal, compressive strength is comparable to metal, but the stiffness is not as good as metal. Tensile strength is close to the yield strength, is more than twice the ABS. Has a strong ability to absorb shock and stress vibration, impact strength is much higher than ordinary plastics, better than acetal resin.

Classification
(1) According to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and free-cutting structural steel three categories, carbon structural steel is divided into engineering construction steel and machine building structural steel two;
(2) According to the smelting method can be divided into flat furnace steel, converter steel;
(3) According to the method of deoxidation can be divided into boiling steel (F), sedentary steel (Z), semi-sedentary steel (b) and special sedentary steel (TZ);
(4) According to the carbon content of carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC ≥ 0.6%);
(5) according to the quality of steel can be divided into ordinary carbon steel (containing phosphorus, sulphur higher), high-quality carbon steel (containing phosphorus, sulphur lower) and high-quality steel (containing phosphorus, sulphur lower) and high-quality steel.

That is, the bolt, nut strength level is the same (bolt 8.8 and nut 8 strength level is the same, because the bolt after the ‘.8’ that is the yield strength is 80% of the tensile strength.)

But consider the use of the situation if the nut is not easy to replace, the bolt is easier to replace, can also be changed to bolt 4.8 nut 5.

There are occasions when the strength of nuts is a little lower than that of bolts, mainly because the failure of bolts is usually not easy to detect, sometimes suddenly, whereas the failure of nuts is easier to detect. The safety aspect is also taken into account. This ensures that when used in conjunction, the life of the screw is longer than the nut, and so that when removing and replacing fasteners, the cost will be cheaper and easier.
