Square and rectangular pipe is a name for square pipe and rectangular pipe, that is, steel pipes with equal and unequal side lengths. It is made of strip steel that has been processed and rolled. Generally, the strip is unpacked, flattened, coiled, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length. The usual delivery length of square and rectangular tubes is 4000mm-12000mm, mostly 6000mm and 12000mm. The square rectangular tube is allowed to deliver short-length and non-fixed-length products not less than 2000mm, and it can also be delivered in the form of an interface tube, but the buyer should cut off the interface tube when using it.

DATIAN (DT) Fastener is famous for producing quality heavy hex nuts. We, one of the professional heavy hex nut manufacturers, have a in house full line heat treatment machine used to improve the hardness and mechanical properties of heavy hexagonal nut in order to serve different high requirement areas. The heavy hex jam nut standard we listed below are most ASTM A194/A563 and ANSI/ASME B18.2.2 heavy hex nuts. Compare to finished hex nuts, the heavy hex nut carry higher grade and slightly wider and thicker diameters to meet the greater length of thread engagement and better resistance to stretching or widening. Contact DT Fastener, a professional nuts and bolts manufacturing company, for more info now! Heavy Hex vs Hex The first thing to declare is that both heavy hex bolt nut and finished hex nuts belong to the hexagon nut classification. Simply put, the difference between them is that heavy hex nuts have larger widths across the flats and heights of the same nominal size. This gives heavy hex nuts higher load retention and tensile strength. This also explains why heavy hex nuts can be heat treated to achieve higher hardness. There are two production processes for Datian Fastener's Heavy hexagon nuts - cold heading and hot heading. The cold heading machine of Datian Fasteners has the ability to form the nut from raw material to finished product at one time. Our cold heading machine integrates the rolling thread machine and the cold heading machine to maximize efficiency, ensure the customer's delivery requirements, and minimize the labor cost, which makes the price of our heavy hexagonal nut competitive all over the world. Hot forming: Generally, hot forming is selected for larger fasteners, and the diameter range are generally 1''~4''~(M30~M100) or even larger. The material used in the hot heading machine is generally round steel, without cold drawing and pickling. The production step is to cut the material first, and then upsetting by the punch. The surface of the semi-finished product of red punching is rougher than that of cold heading. After tapping, the two sides of the nut are chamfered with a CNC machine, and finally it is completed after heat treatment and surface treatment. Cold heading and hot heading are roughly divided into the following steps: Cold heading: wire drawing - cold heading - (heat treatment) - tapping - surface treatment Hot forming: cutting material - red punching - chamfering - turning - (heat treatment) - tapping - surface treatment Or cutting material - upsetting ball - annealing, phosphating - forming - punching - (heat treatment) - tapping - surface treatment. There are many hex nuts suppliers, but we are one of the best choices for you.

The nearly 20 years that DATIAN (DT) Fasteners has specialized in the production of heavy hex bolts. Many customers need to purchase by sets. Our loyal customers usually need to source hex bolts / heavy hex head bolts together with hex nuts. As a professional heavy hex bolt suppliers, DT provides complete heavy hex bolt supply chain services. we are able to produce A307 B heavy hex cap screws, A193 B7 heavy hex bolt, A325 heavy hex screws, etc. Types Of Heavy Hex Head Bolt For Sale Get Heavy Hex Bolt At A Great Price A325 Heavy Hex Bolts A193 B7 Hex Bolt DIN 933 Hex Bolt A307B Heavy Hex Bolts heavy hex bolt heavy hex bolt 1 heavy hex bolt 2 heavy hex bolt 3  Heavy Hex Head Bolt Applications High-strength hexagon bolts are mechanical properties of grade 8.8 or above, and they are all bolts that require heat treatment Bolts made of high-strength steel, or bolts that require a large pre-tightening force, can be called high-strength bolts. High-strength bolts are mostly used for the connection of bridges, rails, high-voltage, and ultra-high-voltage equipment. The fracture of this kind of bolt is a mostly brittle fracture. High-strength bolts applied to ultra-high pressure equipment need to be prestressed to ensure the sealing of the container. Application areas of high-strength bolts: Steel Fabrication, Construction of Railroad Systems, Pumps, and Water treatment, Construction of Modular Buildings, and Renewable and Alternative Energy. Heavy Hex Head Bolt Manufacturing Process Steps Include: Usually, the forming of the bolt head is processed by cold heading. The cold heading forming process includes cutting and forming, single-station single- click, double-click cold heading and multi-station automatic cold heading. An automatic cold heading machine performs multi-station processes such as stamping, heading forging, extrusion and diameter reduction in several forming dies. (1) Use a semi-closed cutting tool to cut the blank, the easiest way is to use a sleeve type cutting tool. (2) During the transfer of short-sized blanks from the previous station to the next forming station, the metal fasteners with complex structures are processed to improve the accuracy of the parts. (3) Each forming station should be equipped with a punch return device, and the die should be equipped with a sleeve-type ejector device. (4) The structure of the main slider guide rail and process components can ensure the positioning accuracy of the punch and the die during the effective use period. (5) The terminal limit switch must be installed on the baffle that controls the material selection, and attention must be paid to the control of the upsetting force. Heat Treatment Of High-Strength Heavy Hex Screw: High-strength nuts and bolts must be quenched and tempered according to technical requirements. The purpose of heat treatment and tempering is to improve the comprehensive mechanical properties of the heavy hex bolt to meet the specified tensile strength value and yield ratio of the product. The heat treatment process has a crucial impact on high-strength fasteners, especially their intrinsic quality. Therefore, in order to produce high-quality heavy hex head bolts, advanced heat treatment technology and equipment must be available. As one of the leading heavy hex bolt manufacturers in China, DT Fastener possesses a complete production line of heavy hex cap screws. Feel free to contact us for more details!
