We are enlisted as top company involved in offering a wide range of HSFG Bolt. We manufactured these using plain carbon steel as well as alloyed steel through controlled heating. Offered bolts are available in different sizes and sizes as per the customers needs. http://www.bigboltnut.com/

BS EN 14399-4 and DIN 6914 is to use
thinner nuts and shorter thread lengths to
obtain the required ductility by plastic
deformation of the threads within the nut.
In Germany, the HV bolt assembly is used
in both preloaded and non-preloaded
applications and it can be argued that in
the event of failure by thread plastic
deformation the assembly still acts as a
non-preloaded assembly.
These assemblies are more sensitive to over-tightening during preloading and
therefore require more site control. If severely over tightened during
preloading the mode of failure by plastic deformation of the engaged thread
of the bolt assembly offers little indication of impending failure.

Hex nuts (also referred to as finished hex
nuts) are available in ASTM A563-A and
compatible with low carbon steel bolts
such as ASTM A307, ASTM F1554 grade
36, SAE grade 2, and AASHTO M183. SAE
grade 5 and grade 8 nuts are also available
in a finished pattern. Since hot-dip
galvanizing typically adds 2.2 to 5 mils of
thickness to the threaded portion of a
fastener, galvanized hex nuts are tapped
oversize to compensate for the corrosion
resistant coating on the bolts.
We manufacture complete range of Stainless steel hex bolts and screws in the
following grades, stocks are readily available and we are manufacturing bolts
diameter from M-12 to M-72 diameter.

A nut designed specifically to thread on to small diameter machine screws.
They are typically thinner than regular nuts with a finished side for butting
up against the surface that does not need a washer.

Stainless Steel Fasteners
A Stainless Steel Fastener is recognized by a helical ridge, known as a male thread or
thread just wrapped around a cylinder. A bolt or screw is kind of fastener. Some screw
threads are known as female thread as they are designed to mate with a
complementary thread, some times in the form of a nut or an object which has an
internal thread formed into it. Because other screw threads are designed to cut a
helical groove in a softer material as the screw is inserted.
