Bolts Except High Tensile

Abstract

(a) Industrial fasteners comprise a very wide range of items like bolts, nuts, washers, studs, wire, nails, etc. Bolts constitute a fairly large part of it. Bolts upto 12mm (upto 15mm in special cases) are made by cold forging process, but bigger sizes need to be made by bolt forging process. Although bolts arc used alongwith nuts, manufacture of bolts only is done by majority of units.
