M.S. FASTENERS AND S.S. FASTENERS
[EIRI/EDPR/1609] J.C. 410
INTRODUCTION
Nuts and Bolts are most commonly used items in the family of industrial fasteners and their demand is fast increasing due to expansion of industries in the country. Bolt is a piece of metal rod whose one end is upset and at the other end threading is done. Nut is a device which rolls on bolt threads. In nuts, internal threading is done while bolts bear external thread. Screw, demonstrate their true merit in the movements, assembly etc, of wooden components. Screws are most popular as fasteners which assemble, or join parts together to be made into a complete unit.
Nuts and Bolts are available in various sizes and shapes. The kind of the classification of bolts and nuts may broadly be those made by the cold and hot process plant (i.e. cold formed & not formed fasteners). Bolts are manufactured by forging (upsetting) and extrusion methods mainly.
Nuts and Bolts are used by the existing industries, repair workshops etc. The sale of these items is increasing day-by-day. As such there is a very good scope for establishment of a few small scale units for the manufacture of nuts and bolts. Nuts are plain, square or hexagonal in shape with flat chambered, or washer crowned top. Like bolts, nuts may be finished or unfinished and may be regular or heavy type. Nuts for special purposes includes, jam nuts, used as locking devices to keep regular nuts from loosening, castellated and slotted nuts, having a square or round bottom slot to accommodate a cotter pin or safety wire which holds them in place, used in automotive and allied fields on operating machinery wing and knurled nuts, designed for use. Where the nut is tightened or loosened with finger pressure only and nuts for use on track bolts, stove bolts and machine bolts.
