8102-A-0440 | فواصل سداسية أماتوم #4-40 × 1/4 بوصة | ألومنيوم (100 / عبوة)

Got these for a small PCB project and they spaced the board perfectly. The #4-40 threads are clean and the aluminum feels solid enough for the price. A hundred in the bag means I'll have plenty for future builds too.

The hex shape on these made alignment during assembly much easier than with round standoffs. I used them to mount a panel in a tight spot and the 1/4 inch length was perfect for the gap I needed to bridge. Clean threads and consistent quality across the whole pack.

I needed a few standoffs for a prototype board and these aluminum ones fit perfectly. The threading was clean and they screwed in without any binding.
