The Allen Bolt, also known as a socket head cap screw, is a threaded fastener with a cylindrical head and an internal hexagonal drive (Allen or hex key) on one end. This design allows for easy and secure tightening or loosening of the bolt using an Allen wrench or hex key.
When the term “Super Duplex Allen Bolt” is used, it typically implies that the bolt is manufactured from Super Duplex stainless steel, offering superior corrosion resistance compared to regular stainless steels. Super Duplex stainless steel is a duplex stainless steel alloy containing a higher content of chromium, molybdenum, and nitrogen, providing enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking.
Super Duplex Allen Bolts are commonly used in applications that require resistance to corrosion, high strength, and reliability. They find applications in industries such as oil and gas, offshore, marine, chemical processing, and other demanding environments where exposure to harsh conditions is expected.
What is the difference between Super Duplex Bolt & Super Duplex Allen Bolt?
The primary difference between a Super Duplex Bolt and a Super Duplex Allen Bolt lies in their head designs & installation methods. A Super Duplex Bolt has a standard hexagonal head, requiring a wrench or socket for tightening. Super Duplex Allen Bolt features a hexagonal socket (Allen) drive in its head, allowing for installation with an Allen wrench.
How do I choose the right size and length of Super Duplex Allen Bolts?
Select the appropriate size and length of Super Duplex Allen Bolts based on the specific application, material thickness, and required load-bearing capacity. Consulting with a knowledgeable supplier or engineer can assist in selecting suitable bolts for your needs.
Can Super Duplex Allen Bolts be used in high-temperature applications?
Yes, Super Duplex Allen Bolts exhibit good resistance to high temperatures, making them suitable for elevated-temperature applications such as heat exchangers & power generation.
