Hotop Carbon Steel Threaded Knurled Thumbscrew Screw on Knobs Grips Black Round Clamping Screw, Black (20 Pieces,M4 x 10 mm)

I bought cpu monitor holders used and was missing these . Works great and great quality.

best thing I ever used

For my work in the live production field, these screws I used to attach monitors for my roadcase PC system for LED walls - great quality and the case they come in is re-usable. Love them

The thumbscrew design makes it easy to mount and remove the display from a stand. They also help when you don't have someone around to help. I like this exact size and I keep them on hand for when the screws provided get lost or sometimes they loosen up and fall out. They can be impossible to find. These however are pretty hard to miss. Someone will always notice them. Being a thumbscrew you can check the tightness at any time and give it a slight turn if necessary. A great upgrade if you buy them and keep them handy!

Recently reworked my home office with a quad monitor setup and these made everything so much easier to mount the monitors and set everything up.Good quality, good price, nice grip, will purchase more when I set up a gaming rig for my kids
