FREQUENTLY ASKED QUESTIONS (FAQ)

What is a round coupling nut used for?

A coupling nut is used to join and extend threaded rods, studs, or bolts of the same thread dimension. The long internal thread provides extensive thread engagement in both components, resulting in a stable bolted joint.

What does it mean that the coupling nut is made of A4 / AISI 316?

A4 (AISI 316 / 1.4401) is an acid-proof stainless steel alloyed with molybdenum, which provides high resistance to chlorides. The material is suitable for marine environments, coastal installations, and other humid or chemically demanding environments.

What is the difference between a round and a hexagonal coupling nut?

Both serve the same function. The round coupling nut has a cylindrical exterior without corners, whereas the hexagonal variant is easier to tighten with a wrench.
