Bolts are generally specified for high temperature or high pressure applications, particularly where bolt heads will bear against flanges. larger than a finished hex bolt of the same diameter. The formula for determining hex size is one-and-a-half times the diameter plus 1/8".

Bolts are widely appreciated for their durability, sturdy construction, corrosion resistant features, and application specific designs. BOLT is used in many types of machines, as these are available in different finishes to meet the varied industrial requirements.


We produce premium quality Bolts from Nickel Alloys, Stainless Steels, Super Alloys, Duplex steels & Super Duplex, Copper & Copper Alloys, with ASTM/ASME/DIN Standards & Specifications. We produce different types of hot forged cold formed bolts in almost all shapes & sizes.

We also provide passivation, quality coating further processing as per client's requirement. Our Manufacturing Size ranges from M6 to M150 with varied length.
