Premium M12 & M20 Brass Dome Cap Nuts Metal Fastening Offered in Sizes T1 T2 T3
 

 
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.
 
3, what is called flange nut?
It is also called nut with pad, flower tooth nut, hexagonal flange surface nut, flange nut, etc. Its size specification is the same as hexagonal nut, except that its gasket and nut are one piece, and there is non-slip tooth pattern underneath, which also increases the surface area contact between the nut and the workpiece, and the anti-loosening performance is stronger compared to the combination of common nut and washer.
Applications
Mainly used for connecting two pipes or pipes and equipment, because of good sealing performance, mostly used in pipeline connection or need to increase the contact surface of the nut on the workpiece, to ensure that the connection of the firmness and sealing. It can withstand high pressure and high temperature to prevent leakage and loosening.
 
4,What is a T-Nut
A nut that looks like a T and prevents parts from loosening and rotating during installation.T-nuts also come in diamond, square and other shapes. T-nuts without threads are called thin-waisted bolts, which are good for joints subjected to variable forces. There are special high-strength bolts for steel structures, with larger heads and different sizes.

Applications
Installation and unloading is convenient, and easy to install the parts in any position which can greatly improve the productivity of labour This is also the reason that the t-nut can be widely used in various milling machines in the T-slot.

Applications

Brass is an alloy made up of copper and zinc, and was originally known as ‘Ogi’. Brass made up of copper and zinc is called ordinary brass, while a variety of alloys made up of more than two elements is called special brass. Brass has excellent electrical conductivity, thermal conductivity, elasticity and mechanical properties, easy to form, welding, cutting, polishing, heat treatment has superplasticity, suitable for the production of electrical conductivity, thermal conductivity, elasticity components, corrosion-resistant structural components, widely used in sanitary ware, electrical and electrical, equipment manufacturing and other industries.

If it is a variety of alloys composed of more than two elements is called special brass. Such as lead, tin, manganese, nickel, iron, silicon copper alloy. Special brass is also called special brass, which has high strength, hardness and chemical resistance.

Ordinary brass is an alloy of copper and zinc.
When the zinc content is less than 35%, zinc can dissolve in copper to form a single phase α, called single-phase brass, good plasticity, suitable for hot and cold pressurised processing.
When the zinc content of 36% to 46%, there is α single-phase copper-zinc-based β solid solution, called dual-phase brass, β-phase brass plasticity and tensile strength rise, only suitable for hot pressure processing.

Special brass is a multi-alloy made up of other alloying elements added to ordinary brass, which is called special brass. The commonly added elements are lead, tin, aluminium, etc., which can be called lead brass, tin brass, aluminium brass accordingly. The purpose of adding alloying elements. The main purpose is to improve the tensile strength and processability. Code: for ‘H + main plus element symbol (except zinc) + copper mass fraction + main plus element mass fraction + other elements mass fraction’ said. For example: HPb59-1 indicates that the mass fraction of copper is 59%, the mass fraction of lead is 1%, and the remaining amount is zinc lead brass.
