Screw threads can be typically seen in numerous mechanical components. Thread rolling is primarily a cold forming approach carried out at room temperature, but a niche does exist for hot rolling when materials are greater than Rockwell C 45, simply because die life would be seriously compromised. Like centerless grinding, its sister approach, the thread rolling method can be in-feed or thru-feed. Thread rolling is the technique of selection for higher-volume production threading applications. Planetary die roll threaders are capable of forming threads on knurling roller tens of thousands of components per hour. Higher speed vertical or inclined flat die reciprocating machines can also create high production rates, and horizontal cylindrical two die machines can rapidly make thousands of feet of threaded rod.
- The higher top quality steel composition is uniform, cold shearing machine high tonnage, cutting head end face smooth and neat, and shoddy material due to the fact the material is poor, cutting head finish face often have meat, or uneven, and no metallic luster. And due to low and inferior material companies cut head, finish there will be a big handle.

A unique character of a handloom fabric is the irregularities or variations present in the weaving which are inherent to the product and which adds to its uniqueness and worth and must not be regarded as a flaw. Handlooms can offer a modern or standard product for each and every strata of society. It projects a distinctive image of sustainability as it is biodegradable and the production approach is atmosphere friendly. The sector provides employment opportunities to lakhs of workers and their households accounting for 12% of the total cloth created in the country.
