Fastener

Fasteners are made from a variety of materials chosen for their strength, resistance to corrosion and specific application needs. You’ll often find carbon steel used for general purposes while stainless steel grades like 304 and 316 are popular for their corrosion resistance and sleek appearance. For high temperature or high pressure situations alloy steels such as ASTM A193 B7, B16 or A194 2H come into play. In more demanding environments like offshore platforms, petrochemical facilities or thermal plants specialized metals like Inconel, Monel or Hastelloy are utilized to guarantee durability and mechanical reliability.

Our fasteners are built to meet the highest global standards guaranteeing you consistent quality and reliable performance. We manufacture according to ASTM standards including A193 for bolts and studs A194 for nuts and A320 for low temperature applications. We also follow DIN and ISO standards for precise dimensions and thread profiles such as DIN 933 DIN 934 ISO 4014 and ISO 898. For petrochemical flange connections we adhere to British standards like BS 4882 while IS 1367 outlines the general mechanical properties. Every batch we produce is rigorously tested to ensure it fully complies with the necessary specifications and traceability requirements.

Yes these fasteners are specifically designed to perform reliably in outdoor and corrosive environments. We use stainless steel grades like 304 and 316 known for their resistance to rust moisture and salt exposure. For extreme conditions such as chemical plants offshore platforms or marine structures we manufacture fasteners from advanced materials like Inconel Monel and Hastelloy. In addition we apply protective surface finishes including PTFE coating hot dip galvanizing black oxide and zinc plating. These combinations ensure long term durability mechanical strength and resistance to harsh weather or chemical exposure.
