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.
