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.
