Frequently Asked Questions

Most frequent questions and answers

What are coupling nuts used for?

Coupling nuts, commonly referred to as extension nuts, are internally threaded nuts that are extended and used to combine two male threads. When extending threaded rods or fastening related objects, coupling nuts are frequently used to link threaded rods or hanger bolts.

Coupling nuts are what grade?

Standard coupling nuts are made from hexagonal or circular bars of ASTM A108 grade 12L14 with a minimum yield strength of 50 Ksi.

What shape does a coupling nut take?

To connect two externally threaded items of the same size and thread pitch, coupling nuts are long hex nuts with chamfers (bevels) at either end. To increase the length, they can unite dissimilar components—such as a hanger bolt and a threaded rod—or join similar components—such as two threaded rods.

How should a coupling nut be measured?

A coupling nut measurement technique A coupling nut’s internal threads (X), the distance between its hexagonal flats (B), and profile height may all be determined (A).

How is a stuck water supply coupling nut removed?

On the base of the toilet tank, look for the connecting nut. Put the bucket in its empty state below the water supply line. Just release the coupling nut using a pair of pliers. Then use your fingers to finish removing the nut.

Is there such a thing as a bolt extender?

In comparison to repairing the footing or installing new epoxy anchor bolts, using a Thread Extender is both quicker and less costly. The Thread Extenders from Light Pole Systems are made to extend anchor bolts that are physically solid but too short to attach a light pole effectively.
