Our range is offered in multiple specifications and in most down to earth prices.

The Acme thread form has a 29° thread angle with a thread height half of the pitch; the peak and crest are flat. The tooth shape also has a wider base which means it is stronger (thus, the screw can carry a greater load) than a similarly sized square thread. This thread form also allows for the use of a split nut, which can compensate for nut wear.[9]
Long-length Acme threads are used for controlled movements on machine tools, testing machines, jacks, aircraft flaps, and conveyors. Short-length threads are used on valve stems, hose connectors, bonnets on pressure cylinders, steering mechanisms, and camera lens movement

Clients can avail the range in industry leading prices.

Both NPT and NPTF have the same threads-per-inch, pitch diameters, and taper-per-inch. The differences come in the major and minor diameters, the root and crest of the threads.
The NPTF thread crests fall with in the parameters of the NPT requirements, but have a smaller range than the NPT.
The NPTF thread roots are different than the NPT thread roots. NPTF thread roots are designed to interfere with the crest of the mating thread with the intention of creating a mechanical seal through thread form deformation at assembly.
NPTF Threads are used where pressure tight sealing is required on threads without using any sealing compound. (Hence also called as the Dry Seal Type).

British Standard Cycle (BSC) or (BSCy) is a British Imperial screw thread standard. Unlike other major British imperial thread standards (British Standard Whitworth and British Standard Fine) the thread runs at a 60 degrees rather than a 55 degrees angle. It generally comes as 26 threads per inch (tpi) and is similar to 1 mm ISO threads which are equivalent of 25.4 threads per inch and also run at a 60 degrees angle. It was originally used with both bicycles and motorcycles.

Thread Depth Measuring Plug Gauge depths for internal threads have often tolerances which though, usually coarse, need to be measured nevertheless. Here one gauge is usually sufficient to measure depth ranging in a tolerance.

Wherever it is expected that the component having multiple coaxial bores should be concentric to the Threading there such type of plug gauges come in handy.

In critical applications, gauges must be quickly cross-verified for their coŕrectness. Since everytime, calibration is not a quickly viable solution and this is where a check plug comes in handy. Its Go end must enter the GO Ring and Nogo end must not  enter the Nogo ring.
