Great value pack

Plenty of washers for multiple projects. Prices are reasonable compared to local hardware stores.

Essential for vibration resistance

Used these on my CNC frame. No loosening after months of use under vibration.

Solid hardware

Steel is hard enough, doesn't strip easily. Wish M10 was included in the set.

Perfect fit for my 3030 profiles

These washers fit perfectly under the T-nuts. Good spring tension and prevents loosening.
