Coupling nuts with inspection holes

A coupling nut with inspection holes makes it easy to check the screw-in depth of the thread ends. For this purpose, the connecting nut has two holes that let you see how far threaded rods or set screws have been screwed in. Other common names for coupling nuts with inspection holes are:

Spacer sleeves with inspection holes
Connecting nuts with inspection holes
Long nuts with inspection holes
Threaded sleeves with inspection holes
Standoffs with inspection holes
Hexagon sockets with inspection holes

By allowing a simple visual check, these fasteners eliminate the need to calculate the screw-in depth.

TITAN’s standard range includes coupling nuts with inspection holes in many standard sizes.

Application and advantages of coupling nuts with inspection holes

To ensure durable and safe connections, it is essential that the connecting parts are screwed into the coupling nut to a sufficient depth. Thanks to the holes on the side of these coupling nuts, this can be checked without the need for any other aids, thus ensuring efficient installation.
