M3 x 30mm + 6mm Male to Female Thread Brass Hexagon Hex Standoff Spacer Pillars - (20 Pcs)

I refurbish a lot of older computers and part of the problem is that the standoffs never quite line up properly with the back side of the case. These, however, do the trick. 12mm is just about the right size to take a motherboard, secure it down, and get it screwed into a backplate or the inside of an older case and have the cards installed in it line up with the expansion slots. No more using M3 nuts to adjust the height of my standoffs!

I use these to attach a dual monitor mount to my curved monitors. Fits perfect and great heavy duty quality

I had metric nuts in hand so these worked fine. I used them as uprights in a 3-level tower for my pi4 with the power supplies and power switch on the bottom, the pi4, and the USB hub on top. I cut sheets of 1/8” opaque smoked lexan and drilled them all identically on the four corners for these posts. Stuck generic silicone feet on the bottom. Worked a treat.

I purchased these to use as spacers on the side panels of my ITX computer build. They work perfectly. Recommend to make sure they fit before purchasing. Great quality. You can tell by the weight.

Is a good standoffs. Will recommend. Accurate

THANKS, BEST SELLER!! VERY BEST RECOMMENDATION

Used this for mount a controller for Xmas lights
