What size square tubing and hardware threads are these plugs compatible with?

These plugs fit standard square tubing with a wall thickness of about 1.5mm to 2.5mm. They feature integrated metric ISO coarse threads in M5, M6, or M8 sizes. Make sure to match your tube's outer dimensions and your desired bolt size before ordering.

Why do these square pipe plugs have a threaded nut hole in the center?

The integrated nut hole lets you easily attach leveling feet, casters, or other threaded hardware to your tubing. It transforms a standard square tube into an adjustable leg or mounting point. This makes them perfect for custom office furniture, shelving, and retail displays.

How do I install these end caps, and do I need any special tools?

You can install these caps quickly using a simple press-fit or snap-in method. They slide into the tube end and stay secure through friction, so you do not need adhesives. A soft mallet can help tap them firmly into place if the fit is tight.
