Manufacturers and Exporters of Quality Threaded Bars from India!

Threaded Rod is simply piece of round bars having threading from start to end either , fully threaded or partially depending on what is the standard it is made for. We can manufacture Threaded Rods as per all most all international standards like ASTM, AISI, DIN, BS, JIS, ISI etc.

This is Nuts Bolts Washers India, a world of Quality threaded Bars in itself fully Integrated company exclusively engaged in manufacturing and exporting quality Threaded Bars from more than a decade. This is not just a fastening firm but also a one door arrangement for all your requirements for Threaded Bars, bolts, Nuts and Washers.

Threaded Bars can be of many type of metals like Carbon Steel to Super Alloys like Monel. Threaded Bars in Carbon Steel are usually being plated eith with zinc or colour coating or even Threaded Bars can be Hot Dipp Galavanized. Hot Dip Galvanized threaded Bars gives the maximum life as it do not gets rusted for years. Carbon Steel Threaded Bars are being used in general or structural uses. Manhufacturing Carbon Steel threaded bars quite easy as compred to other metal Threaded Bars.

Stainless Steel Threaded Bars are High Chromium high Nickel threaded Bars. There is very wide range of Stainless Steel Threaded Bars. 18-8 Stainless Steel Threaded Bars which are nothing other than stainless steel 304 grade threaded bars. This grade is also being called as 18-8 because this grades contains 18 percent Chromium and 8 % Nickel into it and are being used widely in The category of Stainless Steel Threaded Bars. This also covers A2-70 Stainless Threaded Bars and A4-80 Stainless Threaded Bars.

We are manufacturing Threaded Rods from 1 Meter Length to 6 Meter Length.

A-80 Stainless Steel Threaded Bars are of Stainless Steel 316 Grade with some particular physical properties. Nowadays there is one more Stainless material for which demand is incresing and that is being called Duplex Steel threaded Bars. Duplex Steel Threaded Bars also have higher or superior grade being called as Super Duplex Steel. We can manufacture both Duplex Steel Threaded Bars as well as Super Duplex Steel Threaded Bars. We must mention here that to manufacture Super Duplex Steel Threaded Bars is much difficult in comparision to manufacture Super Duplex Threaded Bars. Both Duplex Steel as well as super duplex steel grades are magnetic but anticorrosive in nature.

We are also capable to manufacture threaded bars in super alloys or high performance alloys like Monel 400 Threaded Bars, Hastelloy Threaded Bars or Inconel Threaded Bars as per customer's specific legnth. We are manufacturing Threaded Rods with world class Threads that is as per Go and Not Go Gauge condition as per Metric, BSW, UNC, UNF, BSF etc.

Thread standards of Threaded Bars

There are many systems for specifying the dimensions of screws, but in much of the world the ISO metric screw thread preferred series has displaced the many older systems. Other relatively common systems include the British Standard Whitworth, BA system (British Association), and the SAE Unified Thread Standard.

In addition, the following non-preferred intermediate sizes are specified:
ISO metric thread M14 | M18 | M22 | M27 | M33 | M39 | M45 | M52 | M60 | M68
wrench size (mm) 22 | 27 | 32 | 41 | 50 | 60 | 70 | 80 | 90 | 100

The first person to create a standard (in about 1841) was the English engineer Sir Joseph Whitworth. Whit worth screw sizes are still used, both for repairing old machinery and where a coarser thread than the metric fastener thread is required. Whit worth became British Standard Whit worth, abbreviated to BSW (BS 84:1956) and the British Standard Fine (BSF) thread was introduced in 1908 because the Whit worth thread was a bit coarse for some applications. The thread angle was 55° and a depth and pitch of thread that varied with the diameter of the thread (i.e., the bigger the bolt, the coarser the thread). The spanner size is determined by the size of the bolt, not the distance between the flats.

British Association screw threads (BA)

A later standard established in the United Kingdom was the BA system, named after the British Association for Advancement of Science. Screws were described as "2BA", "4BA" etc., the odd numbers being rarely used, except in equipment made prior to the 1970s for telephone exchanges in the UK. This equipment made extensive use of odd-numbered BA screws, in order—it may be suspected to reduce theft. While not related to ISO metric screws, the sizes were actually defined in metric terms, a 0BA thread having a 1 mm pitch. These are still the most common threads in some niche applications. Certain types of fine machinery, such as moving-coil meters, tend to have BA threads wherever they are manufactured.

Unified Thread Standard

The United States of America has its own system, usually called the Unified Thread Standard, which is also extensively used in Canada and in most other countries around the world. At least 85% of the world's fasteners are dimensioned to Unified thread dimensions, and the biggest selection of fastener sizes and materials are found supplied in this standard.[25] A version of this standard, called SAE for the Society of Automotive Engineers, was used in the American automobile industry. The SAE is still associated with inch-based fasteners by the public, even though the U.S. auto industry (and other heavy industries relying on SAE) have gradually converted to ISO preferred series fasteners for some assemblies from the 1970s onward, because global parts sourcing and product marketing favor international standardization. However, all automobiles sold throughout the world contain both metric (engine assemblies) and Imperial fasteners (for example, spark plugs, oxygen sensors, internal electrical assemblies, body fasteners, lamps, steering, brake and suspension parts).

Machine screws are described as 0-80, 2-56, 3-48, 4-40, 5-40, 6-32, 8-32, 10-32, 10-24, etc. up to size 16. The first number can be translated to a diameter using a formula, the second is the number of threads per inch. There is a coarse thread and a fine thread for each size, the fine thread being preferred in thin materials or when slightly greater strength is desired.

A Unified Miniature screw thread series is defined in ANSI standard B1.10, for fasteners of 0.3 to 1.4 millimeters (0.0118 to 0.0551 inch) diameter. These sizes are intended for watches, instruments, and miniature mechanisms and are interchangeable with threads made to ISO Standard 68.

We can not only manufacture and export Threaded Bars but also we can supply Threaded bars with any world known Third party inspection certifications so as to ensure the world class standard in Threaded Bars like
