Fasteners in Stainless, Duplex Steel and Nickel Alloys
Nuts and Bolts Washers India, a world in itself, fully Integrated company exclusively engaged in manufacturing and exporting quality fasteners like nuts Bolts, Washers, Stud Bolts from more than a decade. This is not just a fastening firm but also a one door arrangement for all your bolts, Nuts, Threaded Bars and Washers requirement.
Our Specialty in Fasteners
“We are specialized in manufacturing and exporting special grade fasteners like Super Duplex Steel, Duplex Steel, Hastelloy, Monel, Inconel, Alloy-20 etc.”
Quality is prime concern
“We belive in delivering world class quality complying to desired International Standards being asked by our valuable Customer.”
An example of an ordered list:
- Super Duplex Steel Stud bolts, Nuts & Washers.
- Monel Alloy ® Stud bolts, Nuts & Washers.
- Stainless Steel Threaded Bars.
Types of Threaded Bars
- Threaded Bars are simple a piece of longer round bars having threading
from start to end fully threaded depending on what is the standard
it is made for.
We are specialized in Stainless Steel ASTM A193 B8 Class 2 Threaded Bars/rods and ASTM A193 B8M Class 2 Threaded Bars/rods
Metals of Bolts

Nickel Alloy Bolts
- There are two type of manufacturing process for Bolts first is
cold forming which recommended for small size fasteners because
of it is economical and other is Hot forging or forming Bolts. As
far as cold formimg is concerned that is vaible and possibble only
in stainless steel regular or very regular grades and not for rare
grades. Here we would like to specify or clear the term regular
and very regular. Regular grades are like AISI 304/304L, 316/316L
only. But there are hundreds of grades in stainless steel fasteners
itself which covers all type of bolts. Not only this but cold forming
is also restricted to some perticular type of Bolts like Hex bolts,
Hex Screws, Socket Head Bolts as per DIN 931, DIN 933 etc. But there
are many shapes and designs in Bolts which are not so regular or
not demanded in bulk quantity like heavy hex bolts, square head
bolts etc.
These kind of Stainless steel fasteners are being manufactured through hot forming process. Hot forming process is not easy and as good as what the first one. This process is legnthy as well and that is why the production is very low in comparision to the first one. But this process is very well recomended for Super Alloys Bolts like Alloy 400, Alloy K-500, Alloy 617, Alloy C-276 etc. Because these metals are very hard in character and that impacts directly to tooling. To manufacture Monel Alloy 400 Bolts or Monel Alloy K -500 is not so hard as far as hardness is concerned in comparision to Inconel Alloy 600 Bolts or Inconel Alloy 617 Bolts or even Inconel Alloy 625 Bolts. Here matter gets more crticial when we come accross to manufacture Haslelloy Alloy C-276 bolts or Hastelloy Alloy C Bolts.
Types of Nuts
- There are three kind of nature of nuts i.e. cold Forging, Hot Forging and Machined Nuts.
Cold forging or cold work nuts are being manufactured by automated process. In India there are several manufacturing plants for manufacturing Alloy 400, Alloy k-500 nuts including us.
Nuts in various Metals available with us like Stainless nuts, duplex steel hex nuts, super duplex heavy hex nuts, nickel alloy hex nuts like monel hex nuts, inconel hex nuts, hastelloy heavy hex nuts, incoloy heavy hex nuts etc.
Types of Washers
- Flat Washers, Spring washers, Square Washers, Machined Washers,
Punched Washers…
We do manufacture and supply washers in all grades of stainless steel like 304/304L, 316/316L, 321, 347, 317L, 904L etc. We do manufacture these washers in Duplex Steel and Super Duplex Steel washers grades like UNS 31803 UNS 2205, UNS 32750, UNS 32760 etc.
We are manufacturing these washers as per customers design and specifications also.
