What are the advantages & disadvantages of SS 321 fasteners?
Stainless Steel 321 Fasteners are used in applications involving extreme temperatures. These fasteners exhibit high toughness at low temperatures and at higher temperatures. Unlike other alloys that experience intergranular corrosion, these fasteners are not sensitive to corrosion within 425°C – 850 °C (the carbide precipitation range). Another advantage is its possibility to change its chemistry to increase its strength at elevated temperatures.
The disadvantage of SS 321 fasteners is their inability to resist corrosion in applications involving sulfuric acid or chlorine solutions, even in smaller concentrations.

What is the difference between SS 321 hex head nuts and UNS S32100 square nuts?
UNS S32100 square nuts are preferred in high-vibration processes. Compared to a head hex nut, they have greater surface contact with the equipment they are being fastened to. Hence, they prevent the loosening of an assembly in a process with high vibrations.

321 stainless steel hex bolts thread length
For bolts that are under 6 inches, the thread length will be twice its diameter with an extra ¼ inch. If a bolt is more than 6 inches in length, the calculated thread length is twice the diameter plus ½ inch.

SS 321 socket cap screw vs deck screw
The construction of a socket cap screw or an Allen bolt is with a cylindrical head and hexagonal drive hole. These threaded fasteners are a part of heavy-duty, high-temperature applications needing permanent assembly. Unlike a socket cap screw, deck screws have a bugle head construction (for a screwdriver). This design permits fastening the screw to the wooden surface without breaking it.
