Good Value

Quality is good, but threads were a bit tight initially. Needed a tap to loosen them up slightly.

Sturdy Spacers

These are solid. Used them on my CNC router build and they held up perfectly under vibration.

Perfect Fit

Fit exactly as expected on M4 bolts. No play in the threads and the length was consistent.

Great for DIY

Used for custom computer standoffs. Look nice and the anodized finish prevents scratching.
