Uxcell 4-Pack Knurled Thumb Nuts – 1/4-20 X 20mm Aluminum Alloy, Diamond Texture, Pass-Through Hole For Tripods, 3D Printers (Dark Red)

About This Product

These knurled thumb nuts are small parts that come in handy for all sorts of adjustments—tripods, 3D printers, camera rigs, and more.

Each one is 1/4-20 thread, 20mm long, with a 10mm outer diameter.
They're made from aluminum alloy, so they're lightweight, corrosion-resistant, and durable.
The diamond knurled texture gives you a solid grip even with sweaty or oily fingers, so you can tighten or loosen them by hand without tools.

The pass-through hole design means you can use them with longer bolts or threaded rods, and the low-profile shape sits flush against your workpiece.

They come in a dark red anodized finish that looks sharp and won't fade.

Great for machinery, automotive, electronics, or furniture assembly.

Simple hand-tighten installation—just thread them on and turn.

A practical little set that keeps things snug.
