Approx. Price: Rs 4,550 / Piece

Product Description:

The comprehensive range of ACME Thread Gauge offered by us is appreciatively evaluated by our clients for cutting edge features displayed in the products. The advanced engineering process and premium components used in the manufacturing process make the product durable, of versatile application capability and resistant to wear and tear and harsh working conditions. 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

Approx. Price: Rs 2,450 / Piece

Product Description:

Our exclusive range of NPTF Thread Gauge- is critically acclaimed by clients for their adaptability and versatility of applications. We offer the range in multiple options and sizes. The accurately engineered range can be obtained in regular and customized options according to the application requirements. Our products have Multi industry application features. 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).
