1.Product Description

?

A coupling nut also known as extension nut?long hex nut ,is a threaded fastener for joining two male threads, most commonly a threaded rod, but also pipes. The outside of the fastener is usually a hex so a wrench can hold it.Long hex nuts.Are cold or Nuts. these long hex nuts are protected using high-grade raw materials. We are among the most prominent manufacturers, suppliers and exporters of long hex Nuts. we make these long hex nuts available in M6 dia. Till M64 dia.

Hex nut according to the nominal thickness is divided into I type, II type and three kinds of thin. The nut is divided into type 1 and type two and type 8 II.
Type I of the hexagonal nut is the most widely used, type 1 nut is divided into a, B, C three, which the class A and class B nut for smaller surface roughness, of high precision machinery, equipment and structure, and C level nut is used for rough surface of high precision machinery, equipment or structure; hexagon nuts, style 2 thickness is relatively thick, often need to dismantle the occasion.
Type 1 nut refers to the nominal height of more than 0.8D m nut six ordinary nut, the type size shall comply with the provisions of GB/T6170;
The height of the type 2 nut is higher than that of the type 1 nut, and the type size should be in accordance with GB/T6175. There are two purposes to increase the type 2 nut: first, by increasing the height of the nut, the nut can be obtained without heat treatment.
Because the D = M16 8 level 1 nuts without heat treatment, the 8 level nut, only D>M16~39 specifications only 2 nuts,
It is clear that the mechanical properties of the 9 type nut without heat treatment can not reach the 1 grade nut. Another purpose of the specified type 2 nut to obtain a better toughness of the 12 grade nut. Due to the increase of the height of the nut, the stress index can be guaranteed under the lower quenching and tempering hardness, thus increasing the toughness of the nut.
According to the classification of tooth distance: standard teeth, regular teeth, fine teeth, very fine teeth and.
According to the material classification: stainless steel six angle and carbon steel six angle nut, copper six angle nut, iron six angle nut.
According to thickness: six angle thick nuts and six angle thin nut.
According to the classification of the use of the method: hot melt copper nut, hot pressed copper nut, embedded copper nut and ultrasonic brass nut GB/T6191

# Coupling nuts are similar to hex nuts with extreme height measurements giving it length
# Used with threaded rod, the coupling nut joins two pieces of threaded rod

A long nut used to connect pieces of threaded rod or other male threaded fasteners
