Raw material · Receiving steel bars from steel mills. ↓

Drawing · Adjusting diameter of steel bars by drawing. ↓

Cutting · Cutting drawn steel bars according to lengths of bolts. ↓

· Forming head of bolts after heating steel bars. In this process, shape and Hot forging

dimensions of bolts head are decided. ↓

· Chamfering the end of bolts. Bolts with pointed end can bo easily assembied Pointing

with nuts or tapped hole. ↓

Shot blasting · Removing scales and burrs presented in hot forging or pointing. ↓

Extruding · Reducing diameter of bolts on thread area. ↓

Roiling · Making threads by rolling bolts on rolling dies. ↓

· This process gives bolts their designed mechanical properlies such as tensile Hear treatment

strength and hardness. Heat treatment condltion differs depending on products grades. ↓

Re- Rolling · Removing thread nicks and scales presented in heat treatment. ↓

Packing · Packaging finished bolts.
